What is ZMA Plus by IO Genix?

IO Genix ZMA Plus is an evening capsule that pairs the classic ZMA base with two sleep-related ingredients. One capsule provides 15 mg of zinc, 200 mg of magnesium, 2 mg of vitamin B6, 500 mg of L-tryptophan and 1.9 mg of melatonin. The bottle holds 60 capsules, which is two months at one a day.

The initials ZMA originally stand for a simple combination: zinc, magnesium, vitamin B6. It has been sold in bodybuilding circles for decades, with standardised doses and clear European claims. The "Plus" version adds melatonin and tryptophan, which shifts the product from recovery towards sleep.

The real active ingredient in this formula is melatonin. The 1.9 mg per capsule are not there for show: it is the only ingredient in the bottle whose effect on falling asleep is recognised at European level, and it is also what dictates the precautions set out on this page. The rest of the Spanish brand's range can be browsed in our IO Genix section, and the other products in the category in our ZMA section.

What is in one ZMA Plus capsule?

The 1.9 mg of melatonin are worth pausing on, because that figure is not chosen at random. In France, a melatonin-based food supplement remains within the food category as long as it does not exceed 2 mg per daily intake; beyond that, it becomes a medicine. This dose therefore sits just under the limit, and it comfortably exceeds the 1 mg threshold that unlocks the authorised claim: melatonin contributes to the reduction of time taken to fall asleep. A second claim exists and is also met: melatonin contributes to the alleviation of subjective feelings of jet lag.

The three minerals and vitamins in the ZMA base each carry authorised claims, and we stick to the official wordings. Zinc contributes to the maintenance of normal testosterone levels in the blood, to normal protein synthesis and to the normal function of the immune system. Magnesium contributes to normal muscle function, to the reduction of tiredness and fatigue and to the normal functioning of the nervous system. Vitamin B6 contributes to the regulation of hormonal activity and to normal protein metabolism.

One honest reservation about the magnesium, because it is worth knowing before you buy: the form used here is the oxide. It is the least well absorbed of the magnesiums on the market, the one that offers the most magnesium per gram but the least magnesium actually taken up. It is also the most likely to have a laxative effect. If magnesium is your main goal, this is not the right product: take a look instead at our magnesium section, where the bisglycinate and citrate forms are better tolerated.

L-tryptophan, at 500 mg, is an essential amino acid that acts as a precursor to serotonin and then to melatonin. No claim is authorised in Europe for tryptophan, and that should be said rather than left to be assumed: its presence in the formula follows a logic of composition, not a demonstrated effect at this dose.

Ingredients list

L-tryptophan, magnesium oxide, bulking agent (microcrystalline cellulose), zinc picolinate, anti-caking agent (magnesium stearate), melatonin, vitamin B6 (pyridoxine hydrochloride). Capsule shell: GELATINE and colouring. No added sugar, no sweetener, no preservative, no lactose.

May contain traces of GLUTEN, EGGS, MILK, FISH and SOYA.

How should ZMA Plus be taken?

Dose: 1 capsule. Liquid: a large glass of water. Timing: 30 to 60 minutes before bedtime, on an empty stomach or at least two hours after the last meal. Frequency: one intake a day, in the evening only. Duration: a 6 to 8 week course, then one to two weeks off.

The instruction to take it away from meals is not a nicety. Tryptophan is an amino acid, and it uses the same transporter as several other amino acids to cross the barrier between the blood and the brain. Taken in the middle of a protein-rich meal, it ends up competing with them and no longer gets through. Two hours after dinner, the way is clear.

The 30 to 60 minute window before bed corresponds to the time melatonin needs to be absorbed and take effect. Taking it as you get into bed delays the effect by just as much. Conversely, taking it far too early can send you to sleep in front of the television.

Do not drive or operate machinery after taking this capsule. The manufacturer says so, and rightly: melatonin causes drowsiness, which is precisely what it is there for. Residual drowsiness on waking is possible in some people; if it happens, bring the time of intake forward rather than reducing the dose, as the capsule cannot be split.

The one to two week break after six to eight weeks of use is good practice, and above all it has the merit of forcing you to check whether the product is still of any use to you. Avoid caffeine in the six hours beforehand: it is probably the most effective lever on this whole page, and it is free. A dark, cool bedroom does the rest. For a different approach to the same subject, our GABA section is built on another molecule.

Who is ZMA Plus for, and who is it not for?

It is aimed at an adult who takes a long time to fall asleep, who is dealing with jet lag, or whose training schedule disrupts their sleep pattern.

It is strictly contraindicated for anyone on antidepressant treatment, because of the known interaction between L-tryptophan and those medicines. The manufacturer prints this in capitals on the packaging, and it is the most important warning attached to this product. It is also not recommended for pregnant or breastfeeding women, nor for children and adolescents.

The French national agency for food safety also recommends caution with melatonin for people with inflammatory or autoimmune diseases, epilepsy or asthma, as well as for those on any drug treatment. In all these cases, the question should be put to a doctor before buying. Never combine this capsule with another source of melatonin or tryptophan: the doses add up.

The capsule shell is made of gelatine: the product is suitable for neither vegetarians nor vegans.

What you should not expect from it. Melatonin reduces the time taken to fall asleep — it does not extend the night and it does not prevent waking during it. It does not treat chronic insomnia: if you have not been sleeping for months, it is a doctor you need to see, not a supplement. And ZMA does not build muscle: zinc contributes to the maintenance of normal testosterone levels, which means avoiding a drop caused by a deficiency, not raising a level that is already normal.

ZMA Plus or melatonin on its own?

A common question in the shop, and the answer depends on exactly what you are looking for.

Melatonin on its own does one thing and does it well: it reduces the time taken to fall asleep, from 1 mg upwards. It comes in various doses, as sublingual tablets or as drops, often for a modest budget, and it brings nothing else. If your only problem is taking too long to drop off, that is the most direct choice and our melatonin section answers it.

ZMA Plus makes sense when you wanted a ZMA anyway. An athlete already taking zinc, magnesium and vitamin B6 in the evening gains by bringing it all together in one capsule rather than swallowing three. In that case the melatonin comes on top of a routine that is already in place, and the product is fully justified.

When is neither the answer? If magnesium is your priority. The oxide used here is poorly absorbed, and 200 mg cover only 53 % of the reference value. A dedicated magnesium, in a better form, will give you more. Likewise, if it is zinc alone that interests you, a dedicated product costs less and can be taken at any hour, without causing drowsiness.

Frequently asked questions

How much melatonin per capsule?

1.9 mg, just under the 2 mg threshold above which melatonin is no longer classed as a food supplement in France. That is almost double the 1 mg threshold that gives entitlement to the claim about reducing the time taken to fall asleep, and it is a straightforward dose for this type of product.

Why take it away from meals?

Because of the tryptophan. This amino acid uses the same transporter as other amino acids to reach the brain; taken during a protein meal, it ends up competing with them. The manufacturer therefore asks for it to be taken on an empty stomach or at least two hours after dinner.

Can it be taken with an antidepressant?

No. This is a strict contraindication printed on the packaging, linked to the interaction between L-tryptophan and those treatments. If you are on antidepressant treatment, do not take this product and talk to your doctor about your sleep.

Does it cause drowsiness the next morning?

It is possible in some people, and the manufacturer flags it. If it happens to you, bring the time of intake forward rather than trying to cut the capsule, which cannot be split. Do not drive or operate machinery after the evening dose.

Is magnesium in oxide form a good choice?

It is the least well absorbed form on the market and the most likely to have a laxative effect. It is acceptable here because magnesium is not the formula's main active. If your goal is a magnesium intake, choose a dedicated product in bisglycinate or citrate form.

Does this product increase testosterone?

No. The authorised claim for zinc is that it contributes to the maintenance of normal testosterone levels in the blood. Maintaining is not increasing: zinc prevents a drop caused by an insufficient intake, it does not raise a level that is already normal in someone who is not short of it.

Can it be taken every night without a break?

The manufacturer provides for 6 to 8 week courses followed by one to two weeks off. Beyond that, and especially if the difficulty falling asleep persists after several courses, the right move is not to carry on indefinitely but to speak to a doctor about it.

Where can you buy ZMA Plus by IO Genix?

The 60-capsule bottle can be ordered from this page, and we ship throughout France and Europe. In the Vendargues shop, about ten minutes from Montpellier, the first question we ask about this product concerns current medication: the contraindication with antidepressants is real and many customers are unaware of it. The second concerns the afternoon coffee, which accounts for a good deal of insomnia. The rest of the range can be browsed in our sports nutrition selection, and B vitamin intakes in our vitamin B section.

What is IO Genix ZMA B6?

ZMA is the generic name of a combination that has become a standard in sports nutrition: zinc, magnesium and vitamin B6, taken once in the evening. This version from IO Genix fits into one capsule a day, in a bottle of 60, i.e. two months' worth.

The forms chosen are zinc picolinate and magnesium citrate, two common and well-tolerated salts, completed by vitamin B6 in the form of pyridoxine hydrochloride. The ingredients list is short: those three actives, magnesium stearate as an anti-caking agent, and a gelatine capsule coloured with titanium dioxide.

That last point is worth reading before you buy: as the shell is gelatine, the product is not suitable for vegetarians. It is information few product pages give, and it is decisive for some buyers. The rest of the Spanish range is in our IO Genix section.

What does one capsule contain?

Other components: anti-caking agent (magnesium stearate), capsule (gelatine, colour: titanium dioxide). Negligible energy value, less than 1 kcal per capsule. NRV within the meaning of Regulation 1169/2011: 375 mg for magnesium, 10 mg for zinc, 1.4 mg for vitamin B6. Pack size: 60 capsules.

Let us start with what sets this formula apart from conventional ZMAs, because that is the point that counts at the moment of buying. Most ZMAs on the market are taken as three capsules and provide roughly 30 mg of zinc, 450 mg of magnesium and 10 mg of B6. Here, everything fits into one capsule, with doses divided by two to three. That is not a flaw: it is a choice, and it has its advantages.

The first: 15 mg of zinc stays below the safety benchmark of 25 mg a day set by EFSA, which is not the case for a ZMA at 30 mg taken continuously. The second: 150 mg of magnesium stays well below the 250 mg a day that EFSA takes as the limit for magnesium provided by supplements. This formula is therefore easier to stack with the rest of what you take, and simpler to keep up over time. One capsule instead of three also means one pill fewer to swallow.

On what these three nutrients do, the authorised wordings are precise. Magnesium contributes to a reduction of tiredness and fatigue, to the normal functioning of the nervous system, to normal muscle function, to electrolyte balance and to normal psychological function. Zinc contributes to the maintenance of normal testosterone levels in the blood, to normal protein synthesis, to the normal function of the immune system and to the protection of cells from oxidative stress. Vitamin B6 contributes to the reduction of tiredness and fatigue, to normal protein and glycogen metabolism, and to the regulation of hormonal activity.

One nuance to keep in mind: the testosterone wording speaks of maintenance of normal levels. That concerns someone whose zinc intake is insufficient, not someone whose status is already fine. Our zinc and magnesium sections let you compare the doses product by product.

How do you take ZMA B6?

Dose: 1 capsule. Liquid: a large glass of water. Timing: one hour before bed, on an empty stomach or at least two hours after the last meal. Frequency: one serving a day. Duration: a course of 8 to 12 weeks followed by a 2-week break, or continuous use according to your needs.

The “two hours after the meal” is not an affectation. Dietary calcium — dairy products above all — competes directly with zinc for intestinal absorption. A ZMA swallowed with a bowl of fromage blanc loses part of its point. For the same reason the manufacturer advises avoiding coffee and tea in the two hours before the serving.

Two precautions on combining, and they matter. Leave at least two hours between this and any calcium or iron. And if you are on a course of antibiotics — tetracyclines, quinolones — be aware that these minerals can reduce their absorption: the manufacturer mentions it, and it is a question for your pharmacist rather than for a product page.

If taking it on an empty stomach makes you feel sick, which does happen with zinc, take the capsule during a light meal. You will lose a little on absorption, and you will see the course through — which matters more over twelve weeks.

Who is this ZMA for, and who is it not for?

It is aimed at active adults, and it suits three situations in particular: a prolonged calorie deficit, heavy sweating in training, or simply the wish to cover three micronutrients in one go in the evening. The one-capsule format makes it far easier to keep up than a three-capsule ZMA.

It is not suitable for vegetarians or vegans: the capsule is gelatine. Nor is it suitable for pregnant and breastfeeding women, or for children and adolescents — those are the statements carried by the manufacturer. In case of kidney or liver disease, or any ongoing medical treatment, consult a doctor before use. Traces of GLUTEN, EGG, MILK, FISH and SOYA are possible.

It is less suitable if you are after the doses of a conventional ZMA. At 15 mg of zinc and 150 mg of magnesium, this formula is deliberately measured: if what you need is a magnesium load, you will have to top up elsewhere, and the manufacturer provides for only one capsule a day.

What not to expect from it. It is not a sleeping pill: ZMA's reputation as a sleep aid is a stubborn one, but no claim of that kind is authorised, and “contributing to the normal functioning of the nervous system” does not mean sending you to sleep. If your problem is falling asleep, our melatonin section answers the question better, and a doctor better still if the trouble settles in. Nor is it a hormonal booster: zinc helps maintain a normal level in someone who is short of it, it does not raise it in someone who is fine.

ZMA, or magnesium and zinc separately?

That is the real trade-off, and it comes down to a problem the ZMA format cannot solve.

Zinc and magnesium compete for intestinal absorption. Bringing them together in a single capsule is convenient, but it amounts to sending them to the same transporters at the same moment. Taking a magnesium in the morning and a zinc in the evening removes the problem, and lets you choose the form of each into the bargain — a magnesium bisglycinate if your digestion is delicate, for instance, rather than a citrate.

ZMA wins on everything else, and that is no small matter. One product instead of two, one serving instead of two, one price instead of two. With a supplement taken every evening for three months, simplicity is the first factor in success: the best protocol is the one you actually follow. This one-capsule version takes that logic further than most of its competitors.

The advice we give most often: start with the ZMA. If after two months you want to fine-tune — more magnesium, another form, splitting the dose — you will know why, and you can then move to separate products. Just check that your multivitamin does not already contain zinc, otherwise you would be doubling up without knowing it.

Frequently asked questions

Why a single capsule when most ZMAs call for three?

Because the doses are more measured: 15 mg of zinc and 150 mg of magnesium, against roughly 30 mg and 450 mg in a conventional three-capsule formula. It is a choice with two concrete advantages: staying below EFSA's safety benchmarks, and having only one capsule to swallow each evening.

Does it really have to be taken on an empty stomach?

The manufacturer advises it, on an empty stomach or two hours after the last meal, to avoid dietary calcium competing with zinc absorption. In practice, if 15 mg of zinc on an empty stomach makes you feel sick, take the capsule during a light meal: you will lose a little, and you will see the course through.

Does ZMA help you sleep?

No sleep claim is authorised for these three nutrients, and we will not make one. Magnesium contributes to the normal functioning of the nervous system, which is not the same thing. The evening serving is explained by absorption precautions, not by a demonstrated sedative effect.

Are the capsules suitable for vegetarians?

No. The shell is gelatine, of animal origin, and contains a colour, titanium dioxide. If you are after a formula in a vegetable capsule, several products in our zinc and magnesium sections offer one, to be taken separately.

How long does a bottle last?

Two months, at one capsule a day for 60 capsules. That corresponds almost exactly to the 8 to 12 week course advised by the manufacturer, followed by a two-week break. Allow a bottle and a half to reach the top end of that range.

Can it be combined with other supplements?

Yes, provided you space them out. Calcium and iron should be taken at least two hours apart, and the manufacturer notes that these minerals can reduce the absorption of certain antibiotics. Above all, check that you are not stacking two sources of zinc: beyond 25 mg a day on a lasting basis, the surplus serves no purpose.

Why magnesium citrate rather than a bisglycinate?

Citrate is a well-absorbed salt, cheaper than bisglycinate, with a laxative effect on transit that some people want and others put up with. Bisglycinate is the best tolerated on the shelf, but it weighs more for the same amount of elemental magnesium — hard to fit into a single capsule. That is the trade-off this format accepts. Our vitamin B section rounds out this intake if B6 is your main concern.

Where can you buy IO Genix ZMA B6?

The 60-capsule bottle can be ordered from this page, and we ship throughout France and Europe. Two months of use in a single bottle is one of the best dose-to-duration ratios on the shelf in this category.

At the Vendargues counter, about ten minutes from Montpellier, this is the product where we take the time to compare labels out loud: between a three-capsule ZMA and this one with a single capsule, the difference in dosage is real, and the right choice depends entirely on what you are already taking. The rest of the minerals can be browsed in our sports nutrition section.

What is Sinob Zinc Bisglycinate?

Sinob Zinc Bisglycinate is a zinc supplement in chelated form, in a vegetable capsule. One capsule provides 25 mg of zinc bisglycinate, i.e. 250% of the nutrient reference value. The bottle holds 60 capsules, which comes to two months at one a day.

Bisglycinate is zinc bound to two molecules of glycine, the smallest of the amino acids. That bond is not cosmetic: it changes the way the mineral crosses the intestinal wall, taking the amino acid transport routes rather than the mineral ones. This is what explains its reputation for being easy on digestion.

In practical terms, it is the form that goes down best on an empty stomach. A zinc sulphate or oxide taken on an empty stomach frequently causes nausea; bisglycinate far less so. On a product meant to be taken every morning, that detail often decides whether the bottle is finished or abandoned. The rest of the German range can be browsed in our Sinob section, and the other products in the category in our zinc section.

What does one Zinc Bisglycinate capsule contain?

250% of the reference value is a high dose, and it deserves to be stated plainly rather than sold as a benefit. The upper safe limit set at European level for zinc in adults is 25 mg per day, from all sources combined — food included. This capsule sits exactly on it. Two practical consequences: one capsule a day and never two, and above all do not stack this product with a multivitamin, a ZMA or any other supplement containing zinc. Intakes add up, and with this mineral an excess is not harmless. We look at these thresholds in detail in our article on zinc bisglycinate dosage.

Why the caution? Because zinc competes with copper for intestinal absorption. A high, prolonged intake may therefore, over time, affect copper status. That is why the manufacturer provides for courses rather than permanent use, and it is a point few product pages mention.

Zinc, on the other hand, is one of the minerals best served by authorised claims, and there are a great many of them. Among the most relevant here: zinc contributes to the normal function of the immune system, to the maintenance of normal testosterone levels in the blood, to normal protein synthesis, to the protection of cells from oxidative stress, to the maintenance of normal skin, hair and nails, to normal cognitive function and to normal macronutrient metabolism. These are the official wordings of the European framework.

Be careful how you read the line “maintenance of normal testosterone levels”: maintaining is not increasing. Zinc prevents a fall caused by an insufficient intake; it does not raise a level that is already normal in someone who is not short of it. It is a nuance the bodybuilding aisle is happy to erase, and it changes everything.

A figure to check on the packaging: the label states “25 mg of zinc bisglycinate” with 250% of the reference value, which corresponds to 25 mg of elemental zinc. The wording leaves some ambiguity as to whether the 25 mg refers to the zinc itself or to the whole complex. We report the declared value without interpreting it.

Ingredients list

Zinc bisglycinate (zinc chelated with glycine), vegetable capsule (hydroxypropyl methylcellulose), anti-caking agent (vegetable magnesium stearate).

May contain traces of GLUTEN, EGGS, MILK, FISH and SOYA.

How do you take Zinc Bisglycinate?

Dose: 1 capsule. Liquid: a large glass of water. Timing: in the morning on an empty stomach. Frequency: one dose a day, never more. Duration: a course of 2 to 3 months, followed by a month off.

Taking it on an empty stomach is possible here, and that is the main appeal of this form. Zinc is better absorbed away from meals, but most forms then cause nausea; bisglycinate is far better tolerated. If you still feel some discomfort, take the capsule with a light breakfast: you will lose a little absorption, which is preferable to giving up on the dose altogether.

Leave two hours between this and an iron or calcium supplement. These three minerals compete for the same intestinal transporters and get in each other's way. The same goes for a meal very rich in fibre or phytates — wholemeal bread, pulses — which markedly reduces zinc absorption. Taking it in the morning on an empty stomach settles all of this at a stroke.

The two- to three-month course followed by a month off is not a commercial constraint: it follows directly from the dose. At 25 mg a day, permanent year-round use is not appropriate. The 60-capsule bottle covers exactly two months, that is, one complete short course.

Zinc combines without overlap with vitamin D or vitamin C, two nutrients that do not compete with it. Before buying, on the other hand, check that your multivitamin or your ZMA does not already provide some.

Who is Zinc Bisglycinate for, and who is it not for?

It is aimed at an adult whose diet provides little zinc: vegetarian and vegan diets first and foremost, since the best food sources are oysters, red meat and offal. The phytates in wholegrain cereals and pulses also reduce the absorption of plant-derived zinc, which widens the gap further.

It is not for you if you already take zinc elsewhere. That is the main warning on this page: between a multivitamin, a ZMA and an immunity complex, it is easy to stack three sources without noticing and to go well beyond the safe limit. Do the sums before adding this bottle to your routine.

It is not recommended for pregnant or breastfeeding women without medical advice, nor for children. If you are on medication, ask a healthcare professional for advice: zinc interacts in particular with certain antibiotics.

What not to expect from it. It does not build muscle and it does not raise the testosterone of a man whose level is normal. It does not prevent colds — no claim of that kind exists. You will feel nothing when you take it, and that is normal: a mineral produces no sensation. If you are wondering about a deficiency, a blood test prescribed by a doctor will answer more reliably than a bottle bought at random.

Bisglycinate or another form of zinc?

The zinc aisle offers at least four different forms, and the gap between them is real.

Zinc oxide is the cheapest and the most widespread in entry-level formulas. It contains a lot of zinc per gram, but it is poorly absorbed and often poorly tolerated on an empty stomach. Sulphate and gluconate do better, with digestive tolerance varying from person to person.

Bisglycinate stands out on two counts: absorption and tolerance. Chelated with an amino acid, it takes a different route in from the classic mineral salts and is taken on an empty stomach without difficulty by most people. That is what justifies its higher price, and it is a premium worth paying on a product taken every morning for two months.

When is another form the better choice? If zinc is not your main objective but one element among several, a multivitamin or a ZMA will be more than enough and will cost you less, with a distinctly more moderate dose — which, given the safe limit, is no bad thing. Our magnesium section, as it happens, applies the same chelated-form logic to another mineral.

Frequently asked questions

How much zinc per capsule?

25 mg, that is, 250% of the nutrient reference value. It is a high dose: the upper safe limit set at European level in adults is 25 mg per day, from all sources combined. One capsule a day, never two, and no stacking with another product containing zinc.

Why bisglycinate rather than another zinc?

Because it is chelated with glycine and takes the amino acid transport routes rather than the mineral ones. The result: better absorption and, above all, tolerance on an empty stomach far superior to that of oxide or sulphate, which frequently cause nausea.

Should it be taken on an empty stomach?

Yes, that is what the manufacturer intends, and this form allows it without discomfort for most people. Zinc is better absorbed away from meals, and in particular away from foods rich in fibre and phytates. If it causes any discomfort, taking it with a light breakfast is still preferable to giving up.

Can it be combined with iron or calcium?

Not at the same time. These three minerals compete for the same intestinal transporters: the manufacturer asks for two hours between them. In practice, zinc in the morning on an empty stomach and iron or calcium with the evening meal settles the question without your having to think about it.

Does zinc increase testosterone?

No. The authorised claim says that it contributes to the maintenance of normal testosterone levels in the blood. Maintaining means preventing a fall caused by an insufficient intake, not raising a level that is already normal. It is a distinction the bodybuilding aisle often erases, and it is an essential one.

How long can you take it for?

The manufacturer provides for courses of two to three months followed by a month off. At this dose, permanent use is not appropriate: a high, prolonged zinc intake can affect copper status, since the two minerals compete for absorption.

Are the capsules suitable for vegetarians?

Yes. The shell is a vegetable capsule made from hydroxypropyl methylcellulose, and the anti-caking agent is a magnesium stearate of plant origin. This is in fact the group most concerned by this product, as the best food sources of zinc are of animal origin.

Where can you buy Sinob Zinc Bisglycinate?

The 60-capsule bottle can be ordered from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, the first question we ask about this product is always the same: are you already taking a multivitamin or a ZMA? At 25 mg per capsule, the answer completely changes the advice, and many customers leave with a more modest dose. The rest of the range can be browsed in our sports nutrition selection.

What is IO Genix Zinc Bisglycinate?

IO Genix Zinc Bisglycinate is a zinc supplement in vegetable capsules, dosed at 15 mg of elemental zinc per capsule, alongside 1.4 mg of vitamin B6. A capsule weighs 0.58 g, which makes it a very compact format to swallow.

The form used is Paul Lohmann® zinc bisglycinate. Paul Lohmann is a German manufacturer of mineral salts, and its name on the label tells you where the raw material comes from, not that it has some magical property. Bisglycinate is zinc bound to two glycine molecules. That bond changes the way the mineral crosses the intestinal wall: it takes the amino acid routes rather than those used by free minerals. In plain terms, it is gentler on the stomach than oxide or sulphate, and that is the real reason to choose it. The rest of the Spanish range can be browsed in our IO Genix section.

The capsule is made of hydroxypropyl methylcellulose, so it is of plant origin: this product is suitable for vegetarian and vegan diets, which is not the case for every capsule supplement.

What does one capsule contain?

The 85 g of carbohydrate per 100 g come from the maltodextrin that carries the powder. On the scale of a single capsule, that amounts to half a gram and two calories: no impact whatsoever on your day.

15 mg of zinc is the ceiling, not an average dose. It is one and a half times the European reference value, and it is also the daily limit that ANSES applies to food supplements in France. In other words, there is nothing to gain by going higher, and there is something to lose: above 25 mg per day from all sources combined, zinc competes with copper and ends up degrading copper status. This product is calibrated to take up all the room available, which has a direct consequence: do not stack it with a ZMA or a multivitamin that already contains some. We look at these thresholds in detail in our article on zinc bisglycinate dosage.

At this dose the authorised claims are numerous and deserve to be quoted word for word, because they say exactly what the product can do: zinc contributes to normal protein synthesis, to the normal function of the immune system, to the protection of cells from oxidative stress, to the maintenance of normal skin, hair and nails, and to the maintenance of normal testosterone levels in the blood. Maintaining is not increasing — that distinction determines what you can expect from this bottle.

Vitamin B6 at 1.4 mg covers the reference value exactly. It contributes to normal energy-yielding metabolism, to the normal functioning of the nervous system, to the reduction of tiredness and fatigue, and to the regulation of hormonal activity. Its presence here is not decorative: B6 and zinc are both involved in protein metabolism, and the pairing is a classic in formulas aimed at athletes. If it is vitamin B6 on its own that interests you, our vitamin B section offers it dosed in its own right.

Ingredients list

Maltodextrin, vegetable capsule (hydroxypropyl methylcellulose), PAUL LOHMANN® zinc bisglycinate, anti-caking agents (magnesium salts of fatty acids and silicon dioxide), pyridoxine hydrochloride (vitamin B6). May contain traces of GLUTEN (WHEAT and OATS), NUTS, PEANUTS, EGGS, MILK, SULPHITES, FISH and SOYA.

How should you take IO Genix Zinc Bisglycinate?

Dose: 1 capsule. Liquid: a glass of water, 200 ml is enough. Timing: in the morning on an empty stomach, or between two meals, leaving at least an hour before or after a full meal. Frequency: one serving a day, never two. Duration: the manufacturer recommends a course of two to three months.

The “on an empty stomach” instruction is not an affectation. The phytates in wholegrain cereals and pulses, the calcium in dairy products and the tannins in tea and coffee all reduce zinc absorption. A capsule taken with a bowl of porridge oats and a coffee delivers markedly less than a capsule taken with a glass of water. If an empty stomach makes you feel sick — it happens with zinc, even in chelated form — take it just after a light meal rather than giving up on it.

Also space it out from your magnesium if you take that in the evening: the two minerals do not directly compete at these doses, but two hours apart is enough to put the question to rest. The same goes for an iron supplement, where the competition is real.

One piece of information is missing and we would rather say so: the manufacturer does not publish the number of capsules per bottle in the information available to us. The format shown on the packaging you receive is what counts when working out exactly how long your course will last.

Who is this zinc for, and who is it not for?

It suits anyone whose diet is low in animal products, since the best-absorbed dietary zinc comes from meat, eggs and seafood. It also suits athletes in a prolonged calorie deficit, whose micronutrient intake falls automatically along with portion sizes. And it suits vegans, since the capsule is plant-based.

It is not for you if you already take a multivitamin or a ZMA containing zinc: the combined total would quickly exceed 25 mg a day, which achieves nothing and disrupts copper in the long run. It is not advised for pregnant or breastfeeding women without medical advice, and it calls for the opinion of a healthcare professional if you are on any treatment — zinc interferes in particular with the absorption of certain antibiotics, which need to be spaced several hours apart.

The product is made in a factory that handles gluten, nuts, peanuts, eggs, milk, sulphites, fish and soya. If you have a severe allergy, that point alone is enough to rule the product out.

What not to expect from it: this is not a hormonal stimulant. Zinc helps maintain normal testosterone levels in someone who is short of it; it does not raise them in someone whose status is already fine. You will probably feel nothing when you take it, and that is normal. For any question relating to a blood test or a suspected deficiency, speak to your doctor rather than doubling the dose.

Zinc bisglycinate on its own, or ZMA?

This is the choice most buyers face, and both answers hold up depending on the context.

A ZMA combines zinc, magnesium and vitamin B6 in a single evening serving. It is the better choice if you are also short of magnesium, which is common among athletes who sweat a lot, and if you would rather have one bottle than two. Its drawback is well known: zinc doses in ZMA are often above 15 mg, and magnesium at a high dose slightly hinders zinc absorption when the two arrive together.

Zinc bisglycinate on its own follows a different logic. You dose exactly the mineral you are targeting, you take it at the most favourable moment of the day, and you remain free to place your magnesium in the evening, separately. It is the better choice if your need is specific, if you already have a magnesium supplement on the go, or if you want to control your daily total to the milligram.

One thing worth noting in passing: the previous description of this product claimed absorption “43% higher” than conventional forms. That figure rests on no verifiable source and we have removed it. Bisglycinate is better tolerated and well absorbed, and that is all that can honestly be said about it.

Frequently asked questions

Should it be taken in the morning or in the evening?

The morning on an empty stomach is the most effective slot, because nothing competes with absorption at that point. The evening works too, provided it is well away from dinner. What matters more than the time of day is consistency: one capsule every day is worth more than two every other day.

Why choose a bisglycinate rather than a zinc oxide?

For digestive tolerance above all. Zinc oxide is cheap but causes nausea and cramps in some users, especially on an empty stomach. Bisglycinate, bound to two glycines, uses a different absorption route and makes itself far less noticed. At an equal dose of elemental zinc, that is where the difference lies.

Is 15 mg of zinc too much?

No, it is exactly the daily limit applied in France for food supplements. The problem is not this capsule, it is the sum total: if you are also taking a multivitamin with 10 mg and a ZMA with 25 mg, you are well above anything useful. Add it all up before you stack.

Is this product suitable for vegans?

Yes. The capsule is made of hydroxypropyl methylcellulose, a material of plant origin, and no ingredient in the formula is of animal origin. The point to watch is manufacturing traces, not the composition.

Can it be combined with vitamin C or omega 3?

Without any problem. Neither of those two families competes with zinc for absorption. The only combinations to space out are iron, high-dose calcium and magnesium taken at the same moment.

How long should a course last?

The manufacturer recommends two to three months. That is consistent with the time needed to rebuild zinc status, which is counted in weeks rather than days. Beyond three continuous months, a break or a blood test is more sensible than simply carrying on.

Does zinc raise testosterone?

No, and nobody can honestly write that it does. The only wording authorised in Europe is that zinc contributes to the maintenance of normal testosterone levels in the blood. In a man whose intake is already sufficient, there is nothing to expect on that front; in someone who is deficient, it helps bring things back to normal.

Where to buy IO Genix Zinc Bisglycinate

You can order it from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, the question we always ask before selling a zinc is “what else are you taking?” — because half the customers who come in for one are already taking it without realising, in another formula. The full range of minerals and vitamins can be browsed in our sports nutrition section.

What is Now Foods Zinc Glycinate?

Now Foods Zinc Glycinate is a zinc supplement in softgel form, sold in a bottle of 120 softgels. The mineral is supplied as glycinate — a salt in which zinc is chelated to glycine, an amino acid. It is the best-tolerated form where digestion is concerned, far ahead of the oxide or the sulphate, and it is the whole point of this product.

Its second distinguishing feature is the carrier. The zinc is not dry-compressed into a capsule but suspended in 250 mg of pumpkin seed oil, inside a softgel. This oil is not an active ingredient in the regulatory sense — we will come back to that — but it explains the product's texture and the way it should be taken.

The formula runs to just a few lines: zinc glycinate, pumpkin seed oil, bovine gelatine for the shell, glycerine, water, carob, beeswax and soya lecithin. The American manufacturer states that production is non-GMO. The rest of the range can be found in the Now Foods section.

What does one softgel contain?

The bottle holds 120 softgels, which is four months at one softgel a day.

30 mg of zinc is a high dose, and that should be stated plainly rather than sold as a benefit. The nutrient reference value is 10 mg: you are at 300%. More to the point, EFSA sets 25 mg a day as the upper safe limit for adults, from all sources combined. A single softgel of this product therefore exceeds that limit on its own, before you even count the zinc in your diet. This is a formula designed for the American market, where the ceilings are not the same as in Europe. It is not a dangerous product, it is a product that should not be taken blindly or long-term without a reason — and certainly not on top of a multivitamin that already contains some.

That said, zinc is a mineral with numerous and firmly established claims. We can state, using the exact wording of the European regulation, that zinc contributes to the normal function of the immune system, to normal protein synthesis, to the maintenance of normal testosterone levels in the blood, to the maintenance of normal hair, nails and skin, to the protection of cells from oxidative stress and to normal fertility and reproduction. Few minerals cover as much ground.

The 250 mg of pumpkin seed oil, on the other hand, carries no health claim authorised in Europe. You will therefore read no promises about it here. Its documented role is that of a fat-soluble excipient: it acts as the carrier inside the softgel.

How should Zinc Glycinate be taken?

Dose: 1 softgel a day. Liquid: a glass of water. Timing: with a meal, preferably dinner. Frequency: 1 serving a day. Duration: the manufacturer advises a course of 2 to 3 months, which may be repeated.

Never take it on an empty stomach. Zinc is the mineral most likely to cause nausea when the stomach is empty, and 30 mg in one go is a good illustration of this: the sensation comes on within half an hour and it is decidedly unpleasant. A meal, even a light one, solves the problem.

Dinner is the most practical slot, for a simple reason of organisation rather than physiology: it is the meal at which people take the fewest other supplements. That matters because zinc competes for absorption with several minerals. Leave at least two hours between it and any iron, calcium or magnesium. That is the rule that counts most in this paragraph, and the one most often forgotten.

On duration: a two to three month course, then a break. Zinc has no perceptible day-to-day effect, and the idea of taking 30 mg continuously all year round is far from trivial — prolonged high-dose supplementation can interfere with copper absorption. If your situation warrants a permanent intake, that is a question for a doctor, backed up by a blood test.

Who is this zinc for, and who is it not for?

It is intended for adults, and its dosage points it towards specific situations: a documented deficiency, a diet low in animal products, or a period of prolonged calorie deficit in an athlete. Outside those cases, a more modest dose is amply sufficient.

The softgel shell is made of bovine gelatine. This product is therefore suitable neither for vegetarians nor for vegans — which is a genuine irony, since diets without animal products are precisely the ones most often short of zinc. The beeswax rules it out of a strict vegan diet as well.

It contains SOYA in the form of lecithin, and traces of WHEAT, GLUTEN, MILK, EGG, FISH and CRUSTACEANS are possible. The manufacturer advises against it for pregnant and breastfeeding women without medical advice and recommends consulting a healthcare professional if you are on any treatment or have a health condition.

It is not suitable if you are already taking a multivitamin, a ZMA or any other supplement containing zinc: the combined total would take you well beyond anything useful. Nor is it suitable if you have no particular reason to supplement — 30 mg a day in someone whose diet already meets their needs brings nothing and is not without consequences in the long run.

What not to expect from it: this is not a testosterone booster. The authorised claim says that zinc “contributes to the maintenance of normal testosterone levels in the blood” — maintaining a normal level is not raising it, and the distinction is not merely rhetorical. Nor is it an acne treatment or a performance product.

Zinc on its own or a multivitamin?

The question is worth asking in that order, because most zinc buyers already have a multivitamin in the cupboard without giving it a thought.

A multivitamin is the better choice if your concern is a general one: an irregular diet, skipped meals, uncertainty about your overall micronutrient coverage. It generally supplies 10 to 15 mg of zinc, a sensible baseline dose, alongside the vitamins and the other minerals. In that case you have no reason to add this product: you would double the zinc without gaining anything else.

Zinc on its own is the better choice in the opposite situation: you know why you are taking it, you want to control that one line precisely, and you do not want to swallow anything else. That covers a vegan diet, a deficiency confirmed by a blood test, or a short period of increased need. The glycinate then has a real argument in its favour: it goes down better than the other forms, and with a mineral known for causing nausea, that is no small detail. One last pointer: if zinc interests you for evening sports use, look instead at ZMA products, which combine it with magnesium and vitamin B6 at more measured doses.

Frequently asked questions

Is 30 mg of zinc a day too much?

It is above the safe limit of 25 mg a day set by EFSA for adults, from all sources combined. One softgel a day taken on an occasional basis, during a two to three month course, remains common practice; a permanent intake at that level, on top of other supplements, does not. If in doubt, ask your doctor or pharmacist for advice.

Is the product suitable for vegetarians?

No. The softgel shell is made of bovine gelatine, and the formula also contains beeswax. That is all the more unfortunate given that vegetarian and vegan diets are among those most often short of zinc. Check this point before ordering.

What is the pumpkin seed oil for?

It serves as a fat-soluble carrier inside the softgel: it is the medium in which the zinc glycinate is suspended. As no health claim is authorised in Europe for this oil, we will not attribute any to it, whatever assertions you may read elsewhere.

Why should it not be taken with iron or calcium?

Because those minerals use the same intestinal transporters and get in each other's way. The manufacturer recommends leaving two hours between servings. In practice: iron at breakfast, zinc at dinner. It is the simplest rule, and it is enough.

How long does the bottle of 120 softgels last?

Four months at one softgel a day, which is longer than the two to three month course advised by the manufacturer. In other words, one bottle covers a full course and you will have some left over. Store it out of the reach of children, in a dry place away from light.

Is glycinate better absorbed than zinc oxide?

Above all it is better tolerated: chelation to glycine limits gastric irritation, and that is a real benefit you can verify day to day. On absorption itself, we will not repeat any numerical multiplier: those comparisons circulate widely and are validated by no health authority.

Can it be taken at the same time as a whey protein or a creatine?

Yes, there is no known interaction between zinc and a protein powder or creatine. The only thing to watch is other sources of zinc: multivitamins, ZMA, immunity complexes. Add up the milligrams before drawing any conclusion, keeping the limit of 25 mg a day in mind.

Where can you buy Now Foods Zinc Glycinate?

It can be ordered from this page, and we ship throughout France and Europe.

Zinc is one of the few supplements for which we sometimes advise against buying over the counter at our shop in Vendargues, about ten minutes from Montpellier. Not because the product is poor — it is well formulated — but because at 30 mg the question “are you already taking some elsewhere?” needs to be asked beforehand, not afterwards. The rest of our everyday supplements can be found in the sports nutrition section.

What is Nutriting nuZinc?

Nutriting nuZinc is a zinc supplement in vegetable capsules, providing 15 mg of elemental zinc per capsule, i.e. 150% of the nutrient reference value. The bottle holds 90 capsules, which covers exactly three months at one serving a day.

The form used is zinc bisglycinate TRAACS®, a raw material from the American manufacturer Albion. The principle is the same as for any bisglycinate: the zinc is bound to two glycine molecules, forming a structure that is electrically neutral and stable in the digestive tract. The practical consequence, the one that genuinely counts: this zinc goes down far better than an oxide or a gluconate in people with a sensitive stomach.

What really sets this product apart is how short its ingredients list is: four lines in all, including the capsule shell. No colouring, no titanium dioxide, no pointless bulking agent. The rest of the French range is in our Nutriting section.

What does one nuZinc capsule contain?

The manufacturer publishes no energy values for this product, and the question makes little sense for a capsule of this size: the calorie contribution is nil over the course of a day. Nor does it disclose the exact quantity of magnesium carbonate or olive oil, which are processing aids rather than actives.

15 mg is the French ceiling for a food supplement, not an average dose. ANSES sets that value as the daily intake not to be exceeded in supplements, and EFSA puts the safety limit from all sources combined at 25 mg a day. In other words, this bottle already takes up all the available room. The consequence is direct and worth spelling out in full: if you are also taking a multivitamin or a ZMA containing zinc, you are going over the ceiling without realising it. We look at these thresholds in detail in our article on zinc bisglycinate dosage.

At this dose the authorised claims are numerous, and it is worth quoting them as they stand because they say precisely what the product can do: zinc contributes to the normal function of the immune system, to normal protein synthesis, to the protection of cells from oxidative stress, to the maintenance of normal skin, hair and nails, to normal cognitive function, to normal fertility and reproduction, and to the maintenance of normal testosterone levels in the blood. All of these wordings speak of maintenance and normal function: they concern someone whose intake is insufficient, not an improvement beyond normal.

A word on a figure that gets passed around. The previous description on this page announced absorption “up to 43% better than zinc gluconate”, based on a comparative study by the producer of the raw material. We have removed that figure: it comes from the supplier itself, it cannot be verified independently, and it turns up word for word on products from different brands. What can honestly be said about bisglycinate is that it is well absorbed and markedly better tolerated. That is already a good reason to choose it.

Ingredients list

Magnesium carbonate (anti-caking agent), vegetable capsule (shell: pullulan), zinc bisglycinate (Albion®), organic olive oil. Gluten-free, lactose-free, soya-free, no declared allergen. No titanium dioxide, no colouring, no animal gelatine, no nanoparticles, no GMOs, not irradiated. Suitable for vegetarians and vegans. Made in France.

How do you take nuZinc?

Dose: 1 capsule. Liquid: a glass of water, 200 ml is enough. Timing: away from meals, ideally in the morning or mid-afternoon, at least an hour away from a full meal. Frequency: one serving a day. Duration: the manufacturer recommends a course of at least two to three months, repeatable all year round.

The “away from meals” instruction has a precise reason. The phytates in wholegrain cereals and pulses, along with the calcium in dairy products, bind zinc in the gut and reduce its absorption. A capsule taken with a bowl of wholegrain oats delivers markedly less than a capsule taken with a glass of water. If an empty stomach does not agree with you, shift it to an hour after a light meal rather than dropping the serving altogether.

Two supplements call for genuine spacing: iron and copper. They use the same intestinal transporters as zinc and get in each other's way. If you are taking iron, put it in the morning and the zinc in the afternoon, or the other way round. Magnesium is less of a problem, but two hours apart saves you having to think about it.

A three-month course is not an arbitrary length: rebuilding zinc status takes weeks, and a month is generally not enough to observe anything at all. The 90-capsule bottle is sized for exactly that.

Who is nuZinc for, and who is it not for?

The manufacturer clearly identifies the profiles concerned, and they match what we see over the counter: vegetarians and vegans, whose diet supplies zinc that is less well absorbed because of phytates; athletes, who lose it through sweat and use more of it; older people; and those with chronic digestive disorders.

The capsule is made from pullulan, a material obtained by fermentation of tapioca: the product is therefore suitable for vegetarians and vegans, which is not the case for most conventional capsule supplements. It is also gluten-free, lactose-free, soya-free and free of declared allergens, which makes it one of the simplest formulas on the shelf for anyone with allergies.

It is for adults only. In case of pregnancy, breastfeeding or medical treatment, the advice of a healthcare professional is needed before starting — zinc interferes in particular with the absorption of certain antibiotics, which need to be spaced several hours apart.

What not to expect from it: it is not a hormonal stimulant, and it will not raise the testosterone of someone whose status is normal. Nor is it a product whose effect you feel. You will not feel anything, and that is expected: zinc corrects an intake, it does not produce a sensation. Finally, if you suspect a genuine deficiency, a blood test prescribed by your doctor is worth more than prolonged supplementation in the dark.

nuZinc or a multivitamin?

That is the real trade-off, and it depends on what you already know about your diet.

A multivitamin covers a broad range: B, C, D and E vitamins, plus a series of trace elements including, almost always, zinc. It is the better choice if you have nothing else, if your diet is erratic on several fronts, and if you want a single bottle to open in the morning. Its drawback is that it doses each element modestly in order to fit everything in, and makes any individual adjustment impossible.

nuZinc follows the opposite logic: a single mineral, at the exact amount you want, at the time you choose. It is the better choice if you know why you are taking zinc — a vegan diet, heavy training, the winter season — and if you want to keep control of the daily total. It pairs without difficulty with a vitamin C, which does not compete with it.

The classic trap is taking both without doing the arithmetic: 15 mg on one side, often 10 mg on the other, and there you are at 25 mg a day, every day. That is not dramatic in the short term, but over several months it degrades copper status. If you do stack them, alternate every other day.

Frequently asked questions

How long does a bottle last?

Three months exactly, at one capsule a day, the bottle holding 90 capsules. That is also the course length recommended by the manufacturer, which makes the format coherent: one bottle equals one course, with nothing left over and nothing missing.

Should it be taken on an empty stomach?

Preferably away from meals, yes. The phytates in wholegrain cereals and the calcium in dairy products both reduce zinc absorption. If an empty stomach bothers you, taking it at a distance from a light meal is still far preferable to taking it in the middle of a full meal.

Is this zinc suitable for vegans?

Yes. The shell is made from pullulan, obtained by fermentation of tapioca, and no ingredient in the formula is of animal origin. It is a point that sets this product apart from the many supplements in gelatine capsules, and it is all the more relevant given that vegans are among the profiles most concerned by zinc.

What is the difference between TRAACS® and an ordinary bisglycinate?

TRAACS® is a raw-material brand, not a different molecule. It denotes a bisglycinate produced to a given specification, with control of the chelation ratio. The chemistry is the same as that of any other properly manufactured bisglycinate; what you are buying is the supplier's traceability.

Can it be taken all year round?

The manufacturer says it can. That said, at 15 mg a day without a break, it is reasonable to take stock after six months, and a blood test becomes more useful than an automatic renewal. Zinc is not stored by the body, but a prolonged excess ends up disturbing copper.

Does it need to be spaced from iron?

Yes, and it is the only interaction that really matters. Iron, copper and zinc use the same intestinal absorption pathways and compete directly. If you take both, separate them by at least four hours, or put one in the morning and the other in late afternoon.

Does zinc strengthen immunity?

The authorised wording is that zinc contributes to the normal function of the immune system. The nuance is a real one: it helps a system to function normally when intake is insufficient, it does not make it perform better in someone whose status is already fine. That is the only thing a seller can honestly write.

Where can you buy Nutriting nuZinc?

It can be ordered from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, this is the bottle we bring out when someone is after a short formula, free of additives, and readable in three seconds on the back of the pack. On a mineral, that is often the best criterion there is. The rest of the shelf can be browsed in our sports nutrition section.

Qu'est-ce que le Zinc liposomal d'Osavi ?

C'est le zinc d'Osavi en version liposomale. Une gélule végétale apporte 15 mg de zinc sous forme de citrate de zinc encapsulé dans des liposomes, la matière première brevetée Liposovit®-Zn.

La liste est courte : le complexe Liposovit®-Zn, de l'inuline et l'enveloppe de la gélule. Rien d'autre — ni arôme de synthèse, ni colorant, ni charge inutile.

Le zinc contribue au fonctionnement normal du système immunitaire, à une fonction cognitive normale, au métabolisme normal des macronutriments, à la protection des cellules contre le stress oxydatif et au maintien d'une ossature, d'une peau, de cheveux et d'ongles normaux.

Qu'apporte la forme liposomale ?

Un liposome est une petite vésicule faite des mêmes matériaux que les membranes de nos cellules : des phospholipides, ici issus de la lécithine de tournesol. Le minéral y est enfermé plutôt que simplement mélangé à une poudre.

Osavi utilise une technologie liposomale sèche, ce qui permet de la présenter en gélule plutôt qu'en liquide — un format plus simple à doser et à transporter, sans goût.

C'est la différence avec un zinc classique de notre rayon zinc : non pas la quantité, mais la façon dont le minéral est présenté. À vous de voir si cela correspond à ce que vous cherchez.

Ce qui distingue vraiment cette gamme : le contrôle

C'est l'argument central d'Osavi, et il est vérifiable. Chaque lot de production est envoyé à un laboratoire indépendant — J.S. Hamilton ou GBA — et analysé sur la teneur réelle en substances déclarées à l'étiquette, les métaux lourds et la pureté microbiologique. Un certificat d'analyse est publié pour chaque produit, et c'est le sens du logo « Lab Tested » sur le flacon.

Les procédés de production sont par ailleurs certifiés ISO 9001:2015 et ISO 22000:2018.

Questions fréquentes

Combien de zinc par gélule ?

15 mg de zinc, sous forme de citrate de zinc encapsulé en liposomes (Liposovit®-Zn). Une gélule par jour selon l'indication du fabricant.

Qu'est-ce que le Liposovit®-Zn ?

La matière première liposomale utilisée par Osavi : le citrate de zinc est enfermé dans des liposomes faits de phospholipides de lécithine de tournesol, avec de la maltodextrine et du glycérol comme support. C'est écrit sur l'étiquette.

Quelle différence avec un zinc bisglycinate ou un picolinate ?

Ce sont trois façons différentes d'apporter du zinc. Le bisglycinate et le picolinate sont des formes chélatées ; ici le citrate de zinc est encapsulé en liposomes. Notre rayon zinc permet de comparer les étiquettes.

La gélule est-elle végétale ?

Oui, l'enveloppe est en hydroxypropylméthylcellulose. Les autres ingrédients sont le complexe Liposovit®-Zn et l'inuline.

Que signifie « Lab Tested » sur le flacon ?

Que le lot a été analysé par un laboratoire indépendant sur sa composition et sa pureté, et qu'un certificat d'analyse est publié pour le produit. C'est la marque de fabrique d'Osavi.

Où acheter le Zinc liposomal Osavi ?

Vous pouvez le commander sur cette page, et nous expédions partout en France et en Europe. Toute la gamme est sur notre page Osavi.

Qu'est-ce que le Zinc picolinate d'Osavi ?

C'est le zinc d'Osavi sous forme de picolinate, une forme organique chélatée. Une gélule végétale apporte 100 % des besoins journaliers en zinc, soit 10 mg — la mention « 50 mg » du nom désigne le poids du picolinate de zinc, le composé, et non celui du zinc élémentaire.

La liste d'ingrédients tient en trois éléments : inuline, enveloppe de la gélule, picolinate de zinc. Sans gluten, sans lactose, sans soja, sans OGM, et compatible avec une alimentation végétarienne ou végétalienne.

Le zinc contribue au fonctionnement normal du système immunitaire, à une fonction cognitive normale, au métabolisme normal des macronutriments, à la protection des cellules contre le stress oxydatif et au maintien d'une ossature, d'une peau, de cheveux et d'ongles normaux.

Pourquoi le picolinate ?

Le picolinate est un chélate : le minéral est lié à une molécule organique, l'acide picolinique, plutôt que présenté sous forme de sel minéral comme l'oxyde. C'est l'une des formes de zinc les plus utilisées sur ce segment, aux côtés du bisglycinate et du citrate.

Notre rayon zinc regroupe les différentes formes disponibles : l'écart se lit sur l'étiquette, pas sur la promesse.

Le contrôle, argument central de la marque

C'est ce qui nous a décidés à référencer Osavi. Chaque lot de production part dans un laboratoire indépendant — J.S. Hamilton ou GBA — qui vérifie trois choses : la teneur réelle en substances déclarées à l'étiquette, l'absence de métaux lourds et la pureté microbiologique. Un certificat d'analyse est publié pour chaque produit ; c'est le sens du logo « Lab Tested » sur le flacon.

Les procédés de production sont certifiés ISO 9001:2015 et ISO 22000:2018.

Questions fréquentes

Combien de zinc par gélule ?

Une gélule couvre 100 % des besoins journaliers en zinc, soit 10 mg de zinc élémentaire. Les « 50 mg » du nom correspondent au picolinate de zinc, c'est-à-dire au composé complet.

Peut-on le prendre en continu ?

Le zinc se prend volontiers par cures. Si vous l'associez à d'autres compléments, vérifiez qu'ils n'en contiennent pas déjà : c'est le cumul qui pose question, pas le produit isolé.

La gélule est-elle végétale ?

Oui, l'enveloppe est en hydroxypropylméthylcellulose. Le produit est sans gluten, sans lactose, sans soja et sans OGM.

Que signifie « Lab Tested » sur le flacon ?

Que le lot a été analysé par un laboratoire indépendant — J.S. Hamilton ou GBA — sur sa composition, les métaux lourds et la pureté microbiologique, et qu'un certificat d'analyse est publié pour le produit. C'est la marque de fabrique d'Osavi.

Où acheter le Zinc picolinate Osavi ?

Vous pouvez le commander sur cette page, et nous expédions partout en France et en Europe. Toute la gamme est sur notre page Osavi, et notre rayon zinc permet de comparer les étiquettes.

Pourquoi trois formes plutôt qu'une

C'est l'argument de ce produit, et il mérite d'être lu correctement.

Chaque sel de zinc a sa propre cinétique et sa propre tolérance digestive. Le gluconate est la forme la plus classique ; le picolinate est le zinc lié à l'acide picolinique ; le citrate à l'acide citrique. En répartir un tiers sur chacune, c'est ne pas parier sur une seule.

Le vrai intérêt de l'étiquette OstroVit, c'est qu'elle détaille les 5 mg de zinc élément par forme au lieu d'afficher une somme de sels. C'est la façon honnête de présenter un produit « triple ».

Ce que vaut OstroVit sur ce produit

OstroVit fabrique elle-même ce qu'elle vend, dans ses propres ateliers, depuis 2006. C'est ce qui explique à la fois l'étendue du catalogue — près de 700 références distribuées dans plus de soixante-dix pays — et des tarifs que peu de marques tiennent sur des actifs unitaires.

La production est encadrée par les systèmes HACCP, ISO 22000 et GMP, et la marque annonce plus de 7 500 analyses de laboratoire par an sur ses lots.

L'enveloppe de la gélule est en HPMC d'origine végétale, pas en gélatine : le produit convient donc aux régimes végétariens et végétaliens.

Questions fréquentes

Pourquoi trois formes de zinc ?

Parce que chaque sel a sa propre cinétique et sa propre tolérance digestive. En répartir un tiers sur le gluconate, un tiers sur le picolinate et un tiers sur le citrate évite de parier sur une seule forme.

Combien de zinc réel par gélule ?

15 mg de zinc élément, soit 5 mg apportés par chacune des trois formes. L'étiquette détaille la répartition au lieu d'afficher une somme de sels.

Les gélules conviennent-elles aux végétaliens ?

Oui : l'enveloppe est en HPMC d'origine végétale.

Où acheter le Triple Zinc OstroVit ?

Vous pouvez le commander sur cette page, et nous expédions partout en France et en Europe. Toute la gamme est réunie sur notre page OstroVit, et notre rayon Zinc permet de comparer les étiquettes.

Ces références sont également présentées en rayon dans notre boutique de Vendargues, à une dizaine de minutes de Montpellier.

Les compléments alimentaires s'intègrent dans une alimentation variée et équilibrée et un mode de vie sain.

Le picolinate, et le chiffre à vérifier

Le picolinate est le zinc lié à l'acide picolinique, un dérivé du tryptophane. C'est une forme chélatée, très répandue en complément.

Le piège classique de ce rayon : un flacon qui annonce « 50 mg » peut parler du picolinate entier et non du zinc. Ici, pas d'ambiguïté — les 15 mg sont du zinc élément, et c'est le tableau nutritionnel qui le dit.

Deuxième point, moins souvent regardé : le nombre de comprimés. 150, c'est un format généreux ; ramené à la journée de prise, c'est là que se fait la vraie comparaison entre deux flacons.

Ce que le zinc fait reconnu en Europe

Le zinc contribue notamment au fonctionnement normal du système immunitaire, au maintien d'une peau, d'ongles et de cheveux normaux, au maintien d'un taux normal de testostérone dans le sang, à la fertilité et à la reproduction normales, au métabolisme normal des macronutriments, au maintien d'une vision normale et à la protection des cellules contre le stress oxydatif.

Si vous préférez répartir l'apport sur plusieurs formes, notre Triple Zinc de la même marque associe gluconate, picolinate et citrate.

Pourquoi cette marque sur ce rayon

Ce qu'OstroVit fait de mieux, ce sont les formules courtes : un actif, un dosage, une liste d'ingrédients qui tient en une ligne. Sur un produit unitaire, c'est exactement ce qu'on cherche.

La marque produit dans ses propres usines sous HACCP, ISO 22000 et GMP, avec plus de 7 500 analyses en laboratoire par an — c'est la contrepartie de la production intégrée, et c'est ce qui permet ce niveau de prix.

Questions fréquentes

Les 15 mg sont-ils du zinc ou du picolinate ?

Du zinc élément. C'est la lecture correcte, et c'est ce que donne le tableau nutritionnel — un flacon qui annonce un gros chiffre parle souvent du sel entier.

Qu'est-ce que le picolinate ?

Le zinc lié à l'acide picolinique, un dérivé du tryptophane. C'est une forme chélatée très répandue en complément alimentaire.

Quelle différence avec le Triple Zinc ?

Le Triple Zinc répartit les 15 mg entre trois formes — gluconate, picolinate et citrate. Celui-ci n'utilise que le picolinate, en 150 comprimés au lieu de 90 gélules.

Qu'est-ce que le zinc bisglycinate d'INLEAD ?

Une gélule par jour, 120 gélules : le flacon couvre 120 jours, soit quatre mois. C'est le format le plus long de notre rayon zinc.

25 mg, c'est un dosage haut

C'est un choix de formulation assumé par la marque, et c'est une information à avoir avant d'ajouter un multivitamines ou une autre source de zinc par-dessus. Si vous prenez déjà un produit qui en contient, faites l'addition.

Pourquoi le bisglycinate ?

Le zinc, comme le magnésium, est toujours lié à autre chose. Ici c'est la glycine, un acide aminé — on parle de forme chélatée.

L'intérêt pratique est la tolérance digestive. Le zinc est connu pour peser sur l'estomac, surtout à jeun et surtout sous ses formes les plus brutes comme l'oxyde ; les formes chélatées sont celles que l'on tolère généralement le mieux.

Ce qu'il y a d'autre dans la gélule

Trois lignes qui méritent une explication, parce qu'on ne les cache pas.

L'amidon de maïs est le premier ingrédient de la liste. C'est l'agent de charge : il remplit la gélule, parce que 25 mg de zinc ne suffisent pas à la remplir, même sous forme de bisglycinate. L'ordre de la liste reflète les poids, pas l'importance — le principe actif reste le zinc.

Les sels de magnésium d'acides gras et le dioxyde de silicium sont des agents d'écoulement, présents en quantités très faibles. Ils servent à ce que la poudre s'écoule correctement dans la machine à encapsuler.

L'enveloppe est en HPMC, une cellulose végétale : pas de gélatine dans ce produit.

La marque derrière le produit

INLEAD conçoit ses formules et les fait fabriquer, sous certification IFS Broker — le référentiel de sécurité alimentaire des entreprises qui achètent et font produire, audité par un organisme indépendant et centré sur la traçabilité et le suivi des fournisseurs. Le certificat est consultable.

Son catalogue tient en deux moitiés : les compléments d'un côté, les aliments reformulés de l'autre.

Questions fréquentes

Qu'apporte la forme bisglycinate ?

Le zinc y est lié à de la glycine. Les formes chélatées sont généralement les mieux tolérées sur le plan digestif, le zinc étant réputé peser sur l'estomac à jeun.

Pourquoi l'amidon de maïs est-il en premier dans la liste ?

Parce que la liste suit l'ordre des poids. L'amidon est l'agent de charge qui remplit la gélule ; 25 mg de zinc n'y suffiraient pas. Le principe actif reste le zinc.

Les gélules conviennent-elles aux végétariens et végétaliens ?

L'enveloppe est en hydroxypropylméthylcellulose, une cellulose végétale. Il n'y a pas de gélatine.

Une pastille à laisser fondre, dès 4 ans

Le Sambucus Zinc-C de NOW Foods réunit 150 mg d'extrait concentré de sureau (Sambucus nigra, 10:1), 100 mg de vitamine C et 3 mg de zinc dans une pastille à laisser fondre en bouche, au goût naturel d'açaï. 60 pastilles par flacon.

C'est la seule référence de notre rayon zinc que le fabricant destine aux enfants à partir de 4 ans comme aux adultes, et ce n'est pas un hasard : les dosages sont volontairement modérés, loin des 50 mg de zinc des produits de cure. Sans sucres, édulcoré au xylitol et à la stévia.

Des dosages qui tiennent dans les repères

C'est ce qui distingue ce produit du reste du rayon, et ça mérite d'être dit : aucune des trois teneurs ne s'approche des maxima français.

• Zinc : 3 mg — maximum français adulte : 15 mg ;
• Vitamine C : 100 mg — maximum français adulte : 1 000 mg.

Ce que la vitamine C et le zinc font, officiellement

La vitamine C contribue au fonctionnement normal du système immunitaire, à la formation normale de collagène (os, cartilages, peau, dents, gencives, vaisseaux sanguins), à un métabolisme énergétique normal, à réduire la fatigue, au fonctionnement normal du système nerveux, à des fonctions psychologiques normales, à la protection des cellules contre le stress oxydatif, et augmente l'absorption du fer.

Le zinc contribue au fonctionnement normal du système immunitaire, à la synthèse normale de l'ADN et des protéines, au maintien d'une peau, de cheveux, d'ongles et d'une ossature normaux, au maintien d'une vision et de fonctions cognitives normales, à la protection des cellules contre le stress oxydatif, et joue un rôle dans la division cellulaire.

Questions fréquentes

À partir de quel âge ?

Le fabricant indique 4 ans. C'est la seule référence de notre rayon zinc dans ce cas, les autres étant réservées à l'adulte. Demandez tout de même l'avis de votre médecin avant d'en donner à un enfant.

Quel goût ?

Açaï, arôme naturel, légèrement sucré au xylitol et à la stévia — sans sucres ajoutés. La pastille fond lentement en bouche, elle ne se croque pas.

Le sureau est-il efficace ?

Nous vous disons ce qu'il y a dans la pastille et à quelle concentration ; le reste relève de votre appréciation ou de celle d'un professionnel de santé.

Est-ce végane ?

Oui : xylitol, celluloses, arôme naturel, acide stéarique végétal, stévia. Aucun ingrédient d'origine animale.

Les deux piliers de l'immunité dans une seule gélule

Le C-1000 Zinc Immune de NOW Foods associe 1 000 mg de vitamine C et 15 mg de zinc par gélule végétale. Une prise par jour, au repas. Flacons de 90 ou 180 gélules, soit trois ou six mois.

Le zinc est apporté sous forme de bisglycinate Albion™ (75 mg de bisglycinate pour 15 mg de zinc élémentaire), une forme chélatée réputée douce pour l'estomac — un vrai point pratique, le zinc étant souvent reproché pour les nausées qu'il provoque à jeun.

Un dosage calé sur les repères français

C'est ce qui distingue ce produit du reste du rayon zinc, et c'est agréable à écrire pour une fois : les deux teneurs correspondent exactement aux doses journalières maximales recommandées en France.

• Vitamine C : 1 000 mg — maximum français : 1 000 mg ;
• Zinc : 15 mg — maximum français : 15 mg.

Autrement dit, contrairement à nos zincs dosés à 50 mg, celui-ci peut se prendre au long cours sans dépasser les repères. Une seule chose à vérifier : ne pas y ajouter un autre complément de vitamine C ou de zinc, ni un multivitamines qui en contiendrait, puisqu'une gélule remplit déjà le quota.

Ce que ces deux nutriments font, officiellement

Vitamine C

Contribue au fonctionnement normal du système immunitaire (y compris pendant et après un effort physique intense), à la formation normale de collagène (os, cartilages, peau, dents, gencives, vaisseaux sanguins), à un métabolisme énergétique normal, à la réduction de la fatigue, au fonctionnement normal du système nerveux, à des fonctions psychologiques normales, à la protection des cellules contre le stress oxydatif, et augmente l'absorption du fer.

Zinc

Contribue au fonctionnement normal du système immunitaire, à la synthèse normale de l'ADN et des protéines, au maintien d'une peau, de cheveux, d'ongles et d'une ossature normaux, au maintien d'une vision normale, de fonctions cognitives normales, d'un taux normal de testostérone dans le sang, à la fertilité et à la reproduction normales, au métabolisme normal des macronutriments, des glucides, des acides gras, de la vitamine A et des acides aminés, à un équilibre acido-basique normal, et à la protection des cellules contre le stress oxydatif.

Questions fréquentes

Quelle différence avec le C-1000 Zinc & D-3 ?

Le C-1000 Zinc & D-3 ajoute 50 µg de vitamine D3 à la même base. Si vous prenez déjà de la vitamine D, ou si vous n'en voulez pas, c'est cette version-ci qu'il vous faut. Si au contraire vous cherchez les trois nutriments de l'hiver en une prise, prenez l'autre.

Le bisglycinate de zinc, c'est mieux ?

C'est une forme chélatée, généralement mieux tolérée à l'estomac que l'oxyde ou le sulfate.

Quel format choisir ?

Le 180 gélules si vous êtes installé dans la routine : le prix à la gélule y est nettement plus bas, et six mois de cure se tiennent sans problème sur ce dosage.

Est-ce végane ?

Oui : gélule d'origine végétale (hypromellose), acide ascorbique de synthèse, bisglycinate de zinc, stéarate de magnésium végétal.

Disponible à Vendargues

Ce produit est aussi en rayon à la boutique Kiss Nutrition, 285 Rue des Portes Domitiennes, 34740 Vendargues. Apportez l'étiquette de ce que vous prenez déjà : on vérifiera ensemble qu'il n'y a pas de doublon.

Trois ingrédients, et c'est tout

Le Zinc picolinate 50 mg de NOW Foods apporte 50 mg de zinc élémentaire par gélule, issu de 271 mg de picolinate de zinc. La composition complète tient en trois lignes : le zinc, de la farine de riz, une gélule d'hypromellose. Pas de stéarate, pas de dioxyde de silicium, pas de colorant.

Trois formats : 30, 60 ou 120 gélules végétales.

Ce qu'il faut savoir avant de commander

La dose journalière maximale recommandée en France pour le zinc est de 15 mg chez l'adulte. Cette gélule en contient 50 mg, soit plus de trois fois ce repère.

La raison de ce plafond est concrète : le zinc à dose élevée pris longtemps réduit l'absorption du cuivre. Les deux minéraux partagent les mêmes transporteurs intestinaux, et un excès de zinc installé sur plusieurs mois peut créer un déficit en cuivre, avec des conséquences sur la formation des globules rouges et sur le système nerveux.

C'est pourquoi NOW Foods porte lui-même sur l'étiquette, sans détour :

• « Non destiné à un usage prolongé » ;

Notre conseil : une cure de quelques semaines, pas un complément d'entretien. Si vous voulez du zinc à l'année, prenez une référence dosée autour de 15 mg — il y en a plusieurs dans notre rayon zinc, et c'est leur raison d'être. Le format 30 gélules de ce produit est d'ailleurs le plus cohérent avec un usage en cure.

Ce que le zinc fait, officiellement

• au fonctionnement normal du système immunitaire ;
• à la synthèse normale de l'ADN et des protéines ;
• au maintien d'une peau, de cheveux, d'ongles et d'une ossature normaux ;
• au maintien d'une vision normale et de fonctions cognitives normales ;
• au maintien d'un taux normal de testostérone dans le sang ;
• à la fertilité et à la reproduction normales ;
• au métabolisme normal des macronutriments, des glucides, des acides gras, de la vitamine A et des acides aminés ;
• à un équilibre acido-basique normal ;
• à la protection des cellules contre le stress oxydatif ;
• et joue un rôle dans le processus de division cellulaire.

Et le picolinate, alors ?

Le picolinate est un chélate : le zinc y est lié à l'acide picolinique. C'est une forme réputée bien absorbée, et c'est l'argument commercial de ce produit.

Ce que nous pouvons dire, c'est que c'est bien du picolinate qui est dans la gélule, et que la liste d'ingrédients est l'une des plus courtes du rayon.

Questions fréquentes

Picolinate ou bisglycinate ?

Les deux sont des chélates, les deux sont des sources autorisées de zinc. Le critère le plus concret, à nos yeux, reste la dose et la liste d'ingrédients — et sur ce dernier point celui-ci est très sobre.

Est-ce végane ?

Oui : gélule d'origine végétale (hypromellose), farine de riz, acide stéarique végétal. Aucun ingrédient d'origine animale.

Disponible à Vendargues

Ce produit est aussi en rayon à la boutique Kiss Nutrition, 285 Rue des Portes Domitiennes, 34740 Vendargues. Dites-nous ce que vous cherchez : entre une cure courte à 50 mg et un entretien à 15 mg, ce ne sont pas les mêmes produits, et nous avons les deux.

Trois nutriments de l'immunité dans une seule gélule

C-1000 Zinc & D-3 réunit les trois nutriments les plus demandés dès que les jours raccourcissent : 1 000 mg de vitamine C, 50 µg (2 000 UI) de vitamine D3 et 15 mg de zinc. Une seule gélule par jour, et c'est fait.

Le zinc est apporté sous forme de bisglycinate Albion™ (75 mg de bisglycinate pour 15 mg de zinc élémentaire), une forme chélatée réputée douce pour l'estomac — le zinc est souvent reproché pour les nausées qu'il provoque à jeun.

Une particularité à connaître : les trois plafonds, pile

C'est le point le plus important de cette fiche, alors disons-le franchement. Cette gélule atteint exactement les trois doses journalières maximales recommandées en France :

• Vitamine C : 1 000 mg — maximum français : 1 000 mg ;
• Vitamine D : 50 µg — maximum français : 50 µg ;
• Zinc : 15 mg — maximum français : 15 mg.

Autrement dit : une gélule et vous êtes au plafond sur les trois. C'est très pratique — mais cela veut dire aussi qu'il ne faut pas y ajouter un autre complément de vitamine C, de vitamine D ou de zinc, ni un multivitamines qui en contiendrait. Et jamais deux gélules par jour. Vérifiez l'étiquette de ce que vous prenez déjà.

Ce que ces trois nutriments font, officiellement

Vitamine C

Contribue au fonctionnement normal du système immunitaire (y compris pendant et après un effort physique intense), à la formation normale de collagène (os, cartilages, peau, dents, gencives, vaisseaux sanguins), au métabolisme énergétique normal, à la réduction de la fatigue, au fonctionnement normal du système nerveux, à des fonctions psychologiques normales, à la protection des cellules contre le stress oxydatif, et augmente l'absorption du fer.

Vitamine D

Contribue au fonctionnement normal du système immunitaire, au maintien d'une ossature et d'une dentition normales, au maintien d'une fonction musculaire normale, à l'absorption et à l'utilisation normales du calcium et du phosphore, au maintien d'une calcémie normale, et joue un rôle dans le processus de division cellulaire.

Zinc

Contribue au fonctionnement normal du système immunitaire, à la synthèse normale de l'ADN et des protéines, au maintien d'une peau, de cheveux, d'ongles et d'une ossature normaux, au maintien d'une vision normale, de fonctions cognitives normales, d'un taux normal de testostérone dans le sang, à la fertilité et à la reproduction normales, au métabolisme normal des macronutriments, des glucides, des acides gras, de la vitamine A et des acides aminés, à un équilibre acido-basique normal, et à la protection des cellules contre le stress oxydatif.

Questions fréquentes

Le bisglycinate de zinc, c'est mieux ?

C'est une forme chélatée, généralement mieux tolérée à l'estomac que l'oxyde ou le sulfate.

Est-ce végane ?

Non. La gélule est végétale, mais la vitamine D3 provient de lanoline, c'est-à-dire de laine de mouton. Si vous cherchez une D3 végane, orientez-vous vers une version à base de lichen.

Je prends déjà un multivitamines, est-ce compatible ?

Probablement pas, et c'est le point à vérifier avant tout. Regardez les teneurs en vitamine C, vitamine D et zinc de votre multivitamines : si elles sont significatives, le cumul vous ferait dépasser les plafonds. Dans ce cas, choisissez l'un ou l'autre.

Disponible à Vendargues

Ce produit est aussi en rayon à la boutique Kiss Nutrition, 285 Rue des Portes Domitiennes, 34740 Vendargues. Apportez l'étiquette de ce que vous prenez déjà : on vérifiera ensemble qu'il n'y a pas de doublon.

Trois micronutriments, une formule de référence

ZMA est l'abréviation de zinc, magnésium et aspartate : la combinaison associe du zinc, du magnésium et de la vitamine B6, et c'est l'une des formules les plus anciennes de la nutrition sportive.

Trois gélules végétales apportent 30 mg de zinc, 450 mg de magnésium élémentaire et 15 mg de vitamine B6. Le zinc provient de trois sources — mono-L-méthionine, aspartate et oxyde — et le magnésium de l'aspartate et de l'oxyde.

La formule tient en six ingrédients. Deux formats : 90 gélules (30 doses de trois gélules) et 180 gélules (60 doses).

Composition par 3 gélules végétales

Autres ingrédients : hypromellose (gélule d'origine végétale), acide stéarique d'origine végétale, dioxyde de silicium.

Végétalien. Sans blé, gluten, soja, lait, œuf, poisson, crustacés, fruits à coque ni sésame ajoutés.

Le magnésium contribue à une fonction musculaire normale, à une synthèse protéique normale, à un métabolisme énergétique normal et à réduire la fatigue. Le zinc contribue à un métabolisme acido-basique normal, à une synthèse protéique normale et au maintien d'un taux normal de testostérone dans le sang. La vitamine B6 contribue au métabolisme normal des protéines et du glycogène et à réduire la fatigue.

Questions fréquentes

Que signifie ZMA ?

Zinc, Magnésium et Aspartate — les trois composants historiques de la formule, à laquelle s'ajoute la vitamine B6.

Pourquoi trois sources de zinc ?

NOW Foods combine la mono-L-méthionine, l'aspartate et l'oxyde de zinc. Les deux premières sont des formes chélatées, l'oxyde apportant une concentration élevée en zinc élémentaire.

Pourquoi le prendre le soir ?

C'est l'usage traditionnel de la formule, à distance des repas car le calcium, le fer et les fibres d'un repas réduisent l'absorption du zinc et du magnésium.

Quel format choisir ?

90 gélules pour 30 doses, 180 gélules pour 60 doses à raison de trois gélules par jour.

Les gélules conviennent-elles aux végétaliens ?

Oui. L'enveloppe est en hypromellose, d'origine végétale, et la formule ne contient aucun ingrédient d'origine animale.

Ce qu'il faut savoir avant de commander

La dose journalière maximale recommandée en France pour le zinc est de 15 mg chez l'adulte. Ce comprimé en contient 50 mg, soit plus de trois fois ce repère.

Ce que cela implique concrètement, et c'est documenté : le zinc à dose élevée pris longtemps réduit l'absorption du cuivre. Les deux minéraux empruntent les mêmes transporteurs intestinaux, et un excès de zinc installé sur plusieurs mois peut créer un déficit en cuivre, avec des conséquences sur la formation des globules rouges et sur le système nerveux.

D'où les trois mentions que le fabricant porte lui-même sur l'étiquette, et que nous ne cherchons pas à adoucir :

• « Non destiné à un usage prolongé » ;

Notre conseil : une cure de quelques semaines, pas un complément d'entretien. Si vous cherchez du zinc à prendre toute l'année, prenez une référence dosée autour de 15 mg — nous en avons plusieurs dans le rayon zinc, et elles sont faites pour ça. Ce produit-ci répond à un autre usage.

Ce que le zinc fait, officiellement

• au fonctionnement normal du système immunitaire ;
• à la synthèse normale de l'ADN et des protéines ;
• au maintien d'une peau, de cheveux, d'ongles et d'une ossature normaux ;
• au maintien d'une vision normale et de fonctions cognitives normales ;
• au maintien d'un taux normal de testostérone dans le sang ;
• à la fertilité et à la reproduction normales ;
• au métabolisme normal des macronutriments, des glucides, des acides gras, de la vitamine A et des acides aminés ;
• à un équilibre acido-basique normal ;
• à la protection des cellules contre le stress oxydatif ;
• et joue un rôle dans le processus de division cellulaire.

Questions fréquentes

Gluconate, picolinate, bisglycinate : quelle différence ?

Ce sont des sels ou des chélates différents, tous autorisés comme sources de zinc en Europe. Le gluconate est la forme la plus classique et la plus économique.

Pourquoi au cours d'un repas ?

Parce que le zinc à jeun donne très fréquemment des nausées, parfois dans la demi-heure. Un repas règle le problème dans la plupart des cas.

Disponible à Vendargues

Ce produit est aussi en rayon à la boutique Kiss Nutrition, 285 Rue des Portes Domitiennes, 34740 Vendargues. Sur le zinc, venez nous dire ce que vous cherchez : entre une cure courte à 50 mg et un entretien à 15 mg, ce ne sont pas les mêmes produits.

Qu'est-ce que le Zinc, Magnésium et B6 de Skill Nutrition ?

C'est un complexe en gélules qui réunit trois nutriments qui travaillent ensemble : le magnésium, le zinc et la vitamine B6. Un flacon de 90 gélules, soit 30 portions.

La différence se joue sur les formes retenues, et elles sont toutes les trois annoncées en clair sur l'étiquette. Le reste de la gamme se parcourt dans notre rayon Skill Nutrition.

Ce qu'il y a dans le Zinc, Magnésium et B6

La portion de trois gélules apporte 360 mg de magnésium, 15 mg de zinc et 6 mg de vitamine B6. Trois lignes, trois quantités affichées en clair.

Le magnésium est apporté sous forme de citrate, une forme organique bien tolérée. Le zinc est apporté par l'OptiZinc®, un sulfate de zinc mono-L-méthionine : le minéral y est lié à un acide aminé, la méthionine. Et la vitamine B6 est donnée sous sa forme active, le pyridoxal-5-phosphate, celle que l'organisme utilise directement sans conversion préalable.

Le magnésium et la vitamine B6 contribuent à réduire la fatigue. Le magnésium contribue au fonctionnement normal du système nerveux, à des fonctions psychologiques normales, à une fonction musculaire normale et au maintien d'une ossature normale. Le zinc contribue au maintien d'un taux normal de testostérone dans le sang et, comme la vitamine B6, au fonctionnement normal du système immunitaire.

Le reste de la formule tient en deux lignes : de l'inuline, une fibre qui sert de support, et une enveloppe en hydroxypropylméthylcellulose. Pas d'origine animale : le produit est déclaré adapté aux régimes végétalien, casher et halal.

À qui s'adresse le Zinc, Magnésium et B6 ?

À celui qui s'entraîne dur et qui sent que la récupération traîne. Le magnésium et la vitamine B6 agissent sur la fatigue, le magnésium sur la fonction musculaire, le zinc sur le taux de testostérone : c'est le trio que les pratiquants vont chercher quand les charges montent et que les nuits raccourcissent.

C'est aussi le choix de ceux qui lisent l'étiquette avant d'acheter. Les trois formes sont nommées noir sur blanc : citrate pour le magnésium, OptiZinc® pour le zinc, pyridoxal-5-phosphate pour la vitamine B6, chacune avec sa quantité affichée en clair.

Questions fréquentes

Quels sont les bienfaits du zinc dans l'organisme ?

Le zinc contribue au maintien d'un taux normal de testostérone dans le sang, au fonctionnement normal du système immunitaire, au maintien d'une peau, d'ongles et de cheveux normaux, et à la protection des cellules contre le stress oxydatif.

Est-ce que le magnésium aide à dormir ?

Ce que porte l'étiquette, c'est que le magnésium contribue au fonctionnement normal du système nerveux, à des fonctions psychologiques normales et à la réduction de la fatigue. C'est sur ce terrain-là qu'il est attendu.

Le zinc augmente-t-il la testostérone ?

Il contribue au maintien d'un taux normal de testostérone dans le sang. Autrement dit, il aide à tenir le niveau en place, surtout lorsque les apports alimentaires sont justes.

Peut-on associer la vitamine B6 au zinc ?

Oui, c'est même une association classique : les deux contribuent au fonctionnement normal du système immunitaire, et la vitamine B6 contribue en plus au métabolisme normal des protéines et du glycogène.

Quel aliment empêche l'absorption du zinc ?

Les phytates, très présents dans les céréales complètes et les légumineuses, réduisent l'absorption du zinc. C'est l'une des raisons pour lesquelles une forme chélatée comme l'OptiZinc® est utilisée ici.

Quelle forme de magnésium ce complexe utilise-t-il ?

Du citrate, c'est-à-dire des sels de magnésium de l'acide citrique. La portion de trois gélules en apporte 360 mg de magnésium élément.

Ce complexe convient-il aux végétaliens ?

Oui. L'enveloppe est en hydroxypropylméthylcellulose, une gélule végétale, et la marque déclare le produit adapté aux régimes végétalien, casher et halal.

Où acheter le Zinc, Magnésium et B6 de Skill Nutrition ?

Ici même, chez KISS NUTRITION. Nous expédions dans toute la France et partout en Europe, et la gamme est tenue en rayon dans notre magasin de Vendargues, à dix minutes de Montpellier, où vous pouvez prendre le flacon en main et lire l'étiquette avant de vous décider.
