What is IO Genix Berberine Complex?
IO Genix Berberine Complex is a capsule supplement combining just two ingredients: a Berberis vulgaris root extract standardised to 97% berberine, and chromium in picolinate form. The bottle holds 60 capsules, i.e. a 30-day course at two capsules a day.
Berberine is a plant-derived alkaloid, recognisable by its bright yellow colour, found in the bark and roots of barberry. The plant was long used as a dye before finding a place in traditional herbal medicine, in China as in India. It is now one of the most debated plant extracts in the field of metabolism.
The second ingredient, chromium, is a trace element that the diet supplies in very small amounts, mainly through wholegrain cereals, meat and pulses. The rest of the Spanish range can be found in our IO Genix section, and the other products in the category in our berberine section.
What does a dose of Berberine Complex contain?
| Composition | Per 2 capsules (daily dose) | % NRV |
|---|---|---|
| Berberis vulgaris root extract | Standardised to 97% berberine | Not established |
| Chromium (picolinate) | Amount not published by the manufacturer | Not published |
| Shell | Gelatine capsule, free from titanium dioxide | |
| Pack size | 60 capsules, i.e. 30 daily doses | |
This is better said plainly than glossed over: the manufacturer publishes the standardisation of the extract, but neither the amount of extract nor the amount of chromium per capsule. We are not going to invent them. Standardisation to 97% berberine is a useful quality indicator — it points to a very concentrated extract, where many products settle for 5 or 10% — but a percentage without milligrams does not let you work out the dose you are actually swallowing. The label on the bottle you receive is what counts, and that is where you should look.
That gap has a direct bearing on what we can write about the chromium. The two wordings authorised in Europe for this trace element are “chromium contributes to the maintenance of normal blood glucose levels” and “chromium contributes to normal macronutrient metabolism”. They apply only above a minimum threshold per portion, and without a published amount, we cannot verify that the threshold is met. So we are reproducing what the manufacturer puts on its label, without adopting it as our own.
For berberine itself, the position is simpler and clearer: no health claim is authorised in Europe for this molecule. Not for blood glucose, not for weight, not for cholesterol, not for digestive transit. Plenty is written about this extract; none of it may appear on a French product page, and none of it is a substitute for medical advice.
Ingredients list
Berberis vulgaris root extract (97% berberine), chromium picolinate, capsule (GELATINE), anti-caking agent (magnesium salts of fatty acids). The capsules are declared free from titanium dioxide.
May contain traces of GLUTEN, NUTS, EGG, MILK, FISH and SOYA.
How do you take Berberine Complex?
Dose: 2 capsules. Liquid: a large glass of water. Timing: in the morning, preferably with breakfast. Frequency: one serving a day, do not exceed it. Duration: the manufacturer recommends a course of at least one month, which is exactly what one bottle covers.
Do not take it on an empty stomach. The manufacturer says so, and it is a comfort instruction that genuinely matters here: berberine is poorly tolerated on an empty stomach by a lot of people, with nausea or digestive discomfort as a result. Taken with breakfast, the problem usually disappears.
If you still feel some digestive discomfort in the first few days, take one capsule instead of two for a week before moving up to the full dose. That works better than stopping after three days and concluding that the product does not suit you.
One month is the stated minimum duration, and it is also the length of time one bottle covers. An active ingredient of this kind cannot be judged over a week. That said, do not run courses back to back indefinitely without speaking to a healthcare professional: we return to this in the next section, and it is the most important point on this page.
This product combines without overlap with a multivitamin, an omega 3 or a standardised turmeric. Introduce it on its own, without changing anything else at the same time: that is the only way to know how well you tolerate it.
Who is berberine for, and who is it not for?
The manufacturer is unusually explicit on this point, and its list deserves to be read before purchase rather than after. The product is for healthy adults only. It is not recommended for pregnant or breastfeeding women, not permitted for children or adolescents, and requires medical advice for people with diabetes who are on medication, in cases of liver or heart disorders, and for anyone following a course of medication.
The words “course of medication” are not a turn of phrase, and this is the point we explain to every customer at the counter. Berberine acts on liver enzymes and on intestinal transporters involved in the metabolism of a great many medicines. In practical terms, it can alter the blood concentration of a treatment taken at the same time, in either direction. This is not a matter of dosage or excessive caution: if you are taking any medicine at all, that question is one for your doctor or your pharmacist before you open the bottle.
The product contains gelatine: it is suitable for neither vegetarians nor vegans. It may also contain traces of gluten, nuts, egg, milk, fish and soya.
What you should not expect from it: it is not a treatment, and it replaces none. Nor is it a weight-loss product — if that is your goal, a calorie deficit and physical activity do the work, and our weight loss section or our caffeine-free fat burners answer a different logic. No capsule makes up for a diet that is not on track.
Berberine or chromium alone — do you need both?
The question is worth asking since this product combines the two, and it helps to know what each one actually brings.
Chromium is a nutrient in the strict sense, with a defined European reference value and two authorised claims. It is a regulated, well-understood ingredient, with no particular grey areas at the doses usually found in supplements. It is also present in most complete multivitamins, often at a comparable level — check your label before adding more, as doubling up achieves nothing.
Berberine belongs to another category: it is a concentrated plant extract, with no authorised claim, documented drug interactions and real contraindications. That is also what makes this product distinctive: an extract standardised to 97% is no trivial ingredient, and that is precisely why it comes with so many warnings.
If you are simply looking to cover your trace element intake, a complete multivitamin is more rational and cheaper. If it is the Berberis vulgaris extract that interests you specifically, then this product makes sense — provided you have read the list of contraindications and, if you are taking any medication at all, have discussed it with a healthcare professional.
Frequently asked questions
What does “standardised to 97% berberine” mean?
It indicates the berberine content of the root extract used: in 100 mg of extract, 97 mg are berberine. It is a very concentrated extract. One caveat, though: that percentage does not tell you how many milligrams of extract a capsule contains, information the manufacturer does not publish.
Should it be taken with food or away from meals?
With food, and preferably at breakfast. The manufacturer explicitly recommends avoiding it on an empty stomach in order to improve tolerance. It is a piece of advice that makes a real difference: on an empty stomach, berberine causes nausea or digestive discomfort in some people.
Can it be taken alongside medication?
Not without medical advice. The manufacturer explicitly asks for it, and the reason is a serious one: berberine can alter the way the body metabolises many medicines, and therefore their concentration in the blood. Put the question to your doctor or your pharmacist before you open the bottle.
How long does a bottle last?
30 days, at two capsules a day for 60 capsules. That is also the minimum course length the manufacturer recommends, which makes the arithmetic simple: one bottle equals one course. Do not run months back to back without speaking to a healthcare professional.
Are these capsules suitable for vegetarians?
No. The shell is made of gelatine, which is of animal origin. The manufacturer does state, however, that the capsules contain no titanium dioxide, which is useful information for anyone watching additives, but which changes nothing about the vegetarian question.
Does berberine make you lose weight?
No claim of that kind is authorised in Europe for berberine, and we will not be writing one. This product is not a fat burner and replaces neither a calorie deficit nor regular physical activity. If weight loss is your goal, start with those two levers.
Can it be taken if you are diabetic?
Not without prior medical advice. The manufacturer states it in black and white for people with diabetes who are on medication, and it is an instruction to take seriously. That conversation belongs to your own doctor, who knows your treatment and your follow-up.
Where can you buy IO Genix Berberine Complex?
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, this is one of the few products we sometimes refuse to sell on the spot: when a customer tells us they are on medication, we would rather they came back after speaking to their pharmacist. The rest of the range can be browsed in our sports nutrition section.
Qu'est-ce que l'Evolog ?
L'Evolog est une formule en gélules d'extraits végétaux titrés signée Evogen, la marque de Hany Rambod. Le flacon en contient soixante, et chaque gélule réunit quatre extraits chiffrés plus un complexe d'enzymes.
C'est le produit que l'on place autour des repas les plus chargés en glucides, les jours où l'assiette est la plus riche. Le reste de la gamme se parcourt dans notre rayon Evogen.
Ce qu'il y a dans l'Evolog
C'est l'une des étiquettes les plus détaillées de la gamme : chaque ligne porte son chiffre, et trois d'entre elles portent le nom d'une matière première sous licence. La ligne la plus dosée est l'extrait de samare de frêne Glucevia (Fraxinus angustifolia), à 333 mg par gélule.
Vient ensuite l'extrait de feuille de banaba (Lagerstroemia speciosa) à 100 mg, puis la pièce la plus intéressante de la formule : 84 mg de dihydroberbérine sous licence GlucoVantage. Ce n'est pas de la berbérine simple mais sa forme réduite, celle que le fabricant retient pour son passage dans l'organisme. La quatrième ligne est l'acide R-alpha-lipoïque, à 33 mg, dans son isomère R et non en mélange racémique.
Le complexe enzymatique EVOZYME ferme la formule : un ensemble d'enzymes qui visent la digestion des protéines et des glucides. Chaque ligne du panneau porte sa quantité, ce qui permet de comparer un flacon à un autre.
À qui s'adresse l'Evolog ?
Aux pratiquants qui mangent beaucoup et qui suivent leurs glucides de près : prise de masse, jours de recharge, périodes où l'assiette monte à plusieurs centaines de grammes de féculents.
À ceux aussi qui achetaient jusqu'ici leurs extraits séparément. Une berbérine d'un côté, un acide alpha-lipoïque de l'autre, un banaba en troisième flacon : l'Evolog réunit les quatre, ce qui change le nombre de pots dans le placard.
Et à ceux qui lisent les étiquettes avant de payer. Sur un produit à base d'extraits, la différence entre deux flacons tient au titrage et au nom de la matière première. Ici les deux sont écrits, ligne par ligne.
Questions fréquentes
Quels sont les bienfaits de la berbérine ?
Chaque ligne du panneau porte sa quantité, et trois des cinq extraits portent le nom d'une matière première sous licence.
Quelles plantes contiennent de la berbérine ?
C'est un alcaloïde jaune présent dans plusieurs genres botaniques : l'épine-vinette (Berberis vulgaris), le raisin d'Oregon, l'hydraste du Canada, le coptide chinois et l'arbre à liège de l'Amour. C'est de ces plantes que la molécule est extraite pour le marché du complément alimentaire.
Où pousse la berbérine ?
Les plantes qui la portent poussent en Europe pour l'épine-vinette, en Amérique du Nord pour l'hydraste et le raisin d'Oregon, et en Asie de l'Est pour le coptide et l'arbre à liège de l'Amour. La molécule n'est donc pas liée à une seule région du monde.
Pourquoi prendre de la berbérine ?
C'est l'une des molécules les plus demandées du rayon, et son défaut connu est son passage dans l'organisme. L'Evolog ne contient pas de berbérine simple mais de la dihydroberbérine sous licence GlucoVantage, une forme réduite retenue pour cette raison précise.
Comment choisir la berbérine ?
Deux lignes suffisent : la forme et la quantité. Une berbérine simple et une dihydroberbérine ne se comparent pas au milligramme près, et un produit qui annonce une plante sans chiffre ne dit pas ce qu'il contient. L'Evolog annonce 84 mg de dihydroberbérine, nommément.
Où se procurer de la berbérine ?
En gélules, seule ou dans une formule comme l'Evolog qui l'associe à d'autres extraits. On la trouve en magasin spécialisé et en ligne : l'Evolog se commande sur cette page et il est en rayon dans notre magasin de Vendargues.
Quels aliments contiennent de la berbérine ?
Aucun, à proprement parler. Ce n'est pas un nutriment présent dans l'alimentation courante : c'est un alcaloïde extrait d'écorces, de racines et de tiges de plantes qui ne figurent pas au menu. C'est pourquoi elle se vend sous forme d'extrait.
Où acheter l'Evolog ?
Sur cette page : commande en ligne, expédition en France et dans toute l'Europe. Un flacon de gélules est léger, il part sans surcoût avec le reste d'une commande.
Et pour le prendre en main, la boutique KISS NUTRITION est à Vendargues, à dix minutes de Montpellier : l'Evolog y est en rayon. Toute la collection Evogen se commande aussi en ligne.
Qu'est-ce que la Berbérine d'OstroVit ?
C'est un comprimé d'extrait de racine de berbéris, dosé à 500 mg d'extrait, titré à 2 % en berbérine. Le flacon en compte quatre-vingt-dix, et la liste des ingrédients tient en trois lignes. Le comprimé est végétalien, sous la mention VEGE.
La berbérine est un alcaloïde végétal d'un jaune vif reconnaissable, présent dans l'écorce et les racines de l'épine-vinette. La plante a longtemps servi de colorant avant d'entrer dans la phytothérapie traditionnelle. C'est aujourd'hui l'un des extraits végétaux les plus demandés du rayon métabolisme. Le reste de la gamme se parcourt dans le rayon OstroVit.
Ce qu'il y a dans la Berbérine
Le chiffre à lire en entier, c'est celui-là : 500 mg d'extrait, dont 2 % de berbérine, soit 10 mg de berbérine réelle par comprimé. Le panneau l'écrit noir sur blanc, en deux lignes : « extrait de racine de berbéris : 500 mg » puis « dont berbérine 2 % : 10 mg ».
La distinction mérite qu'on s'y arrête, parce que beaucoup de références du marché annoncent un dosage qui correspond à l'extrait et pas à la molécule. Ici, les deux chiffres sont donnés, et l'acheteur sait exactement ce qu'il tient. C'est la seule façon de comparer deux flacons sans se tromper.
Le reste du comprimé, c'est une charge et un antiagglomérant : cellulose microcristalline et dioxyde de silicium. Rien d'autre : le produit se résume à un extrait de racine de berbéris titré et à un poids net de 94 g.
À qui s'adresse la Berbérine ?
À ceux qui connaissent déjà cette molécule et qui veulent un extrait dont le titrage est affiché, plutôt qu'une poudre de racine simplement broyée. Période de sèche, alimentation riche en glucides, retour au sport après une longue coupure : ce sont les moments où ce flacon sort de l'armoire.
Elle parle aussi à ceux qui suivent une alimentation végétalienne : le comprimé ne contient ni gélatine ni ingrédient d'origine animale, et la mention VEGE figure sur l'étiquette. Quatre-vingt-dix comprimés, trois ingrédients, un titrage : il n'y a pas trente-six paramètres à comparer.
Questions fréquentes
Qu'est-ce que la berbérine ?
C'est un alcaloïde végétal d'un jaune vif reconnaissable, présent dans l'écorce et les racines du berbéris, l'épine-vinette. La plante a longtemps servi de colorant avant d'entrer dans la pharmacopée traditionnelle, en Chine comme en Inde.
Quels sont les bienfaits de la berbérine ?
La berbérine est utilisée de longue date en phytothérapie traditionnelle. OstroVit en retient un extrait de racine de berbéris titré à 2 % en berbérine, soit 10 mg par comprimé.
Quand prendre de la berbérine ?
Au moment des repas, avec un grand verre d'eau : c'est le réflexe le plus simple à tenir, et celui que retient la plupart des utilisateurs. Le détail de la prise figure dans l'onglet Conseils d'utilisation.
Quels aliments contiennent de la berbérine ?
Aucun aliment courant, en pratique. La berbérine se trouve dans les racines et l'écorce de certaines plantes, pas dans les fruits ni les légumes du marché : c'est pour cela qu'elle se prend sous forme d'extrait.
Où trouver la plante qui donne la berbérine ?
Le berbéris pousse en Europe, en Asie et en Amérique du Nord. Plusieurs espèces voisines en contiennent aussi : l'hydraste du Canada, le raisin d'Oregon, le phellodendron, le coptide chinois. L'extrait utilisé ici vient de la racine de berbéris.
Est-ce que la berbérine fait maigrir ?
C'est la raison pour laquelle beaucoup la cherchent. La masse grasse se joue dans l'assiette et à l'entraînement, pas dans un comprimé.
Où acheter de la berbérine en France ?
Chez KISS NUTRITION, en ligne avec expédition partout en France et en Europe, ou directement en boutique à Vendargues, à dix minutes de Montpellier. Le reste de la gamme est réuni dans le rayon OstroVit.
Où acheter la Berbérine ?
La Berbérine d'OstroVit s'achète en ligne sur kissnutrition.fr, avec expédition dans toute la France et partout en Europe, suivi de colis compris.
Elle s'achète aussi en magasin, à Vendargues, à dix minutes de Montpellier : le flacon se prend en main, l'étiquette se lit tranquillement et les questions se posent de vive voix. Le reste de la gamme, des poudres aux comprimés, est réuni dans le rayon OstroVit.
Qu'est-ce que le Gluco-B de Naughty Boy ?
Le Gluco-B est un complément en gélules construit autour de la dihydroberbérine, et non de la berbérine classique. Le fabricant emploie la forme brevetée GlucoVantage, et c'est exactement ce qui place cette référence à part dans le rayon.
La nuance n'est pas cosmétique. La dihydroberbérine est le dérivé hydrogéné de la berbérine : une molécule différente, nettement plus rare sur le marché, et réputée pour sa meilleure absorption. Là où la plupart des références du rayon se contentent de berbérine HCl, le Gluco-B part sur la forme supérieure. Le reste de la gamme est dans le rayon Naughty Boy.
Ce qu'il y a dans le Gluco-B
Deux actifs, pas un de plus. Le GlucoVantage, qui est la dihydroberbérine brevetée, et un extrait de poivre noir BioPerine. Pas de poudre de remplissage, pas de mélange propriétaire derriére lequel se cacher : une formule courte, lisible, qui mise sur la qualité de l'actif plutôt que sur la longueur de la liste.
Le BioPerine est l'extrait de poivre noir le plus utilisé de l'industrie, standardisé en pipérine. Il revient dans la plupart des formules où l'actif principal a besoin d'un coup de pouce à l'assimilation, et sa présence ici n'a rien d'anecdotique : c'est le compagnon classique des ingrédients végétaux de ce type.
Les formes employées sont annoncées sans ambiguïté : GlucoVantage pour la dihydroberbérine, BioPerine pour le poivre noir. Les quantités exactes de chaque actif sont imprimées sur l'étiquette du flacon, ligne par ligne.
À qui s'adresse le Gluco-B ?
À celui qui connaît déjà la berbérine et cherche la forme au-dessus. C'est un produit de connaisseur : on ne tombe pas sur la dihydroberbérine par hasard, on la cherche. Les pratiquants qui travaillent leur composition corporelle sur plusieurs mois, ceux qui soignent leur hygiène de vie autant que leurs séances, sont le public naturel de cette référence.
Il s'adresse aussi à ceux qui veulent une formule courte. Beaucoup de compléments de ce rayon empilent huit ou dix ingrédients pour faire riche sur l'emballage. Ici, deux lignes : l'actif et son compagnon d'assimilation. C'est plus simple à intégrer dans une routine où vous prenez déjà autre chose, et plus facile à évaluer.
Questions fréquentes
Quels sont les bienfaits de la berbérine ?
La berbérine est un alcaloïde végétal utilisé depuis très longtemps en phytothérapie traditionnelle, aujourd'hui l'un des actifs les plus étudiés du rayon. Elle intéresse surtout ceux qui surveillent leur équilibre métabolique et leur composition corporelle.
Quelle est la différence entre berbérine et dihydroberbérine ?
Ce ne sont pas deux noms pour la même chose. La dihydroberbérine est le dérivé hydrogéné de la berbérine, une molécule distincte, beaucoup plus rare en rayon et réputée mieux absorbée. C'est elle, et elle seule, qui compose le Gluco-B.
Pourquoi prendre de la berbérine ?
Parce que c'est l'un des rares actifs de phytothérapie dont on parle autant dans le milieu de la nutrition sportive que dans celui du bien-être. On la retrouve dans les routines de sèche comme dans celles des pratiquants qui travaillent leur hygiène de vie sur la durée.
Quelle berbérine choisir ?
Regardez la forme avant tout le reste. Une berbérine HCl brute et une dihydroberbérine brevetée comme le GlucoVantage ne se comparent pas, ni sur la rareté ni sur le travail de formulation. Vérifiez ensuite que la forme est nommée noir sur blanc sur l'étiquette.
Quelle plante contient de la berbérine ?
On la trouve dans plusieurs plantes, au premier rang desquelles l'épine-vinette (Berberis vulgaris), mais aussi le coptis chinois et l'hydraste du Canada. C'est elle qui donne à ces racines et à ces écorces leur couleur jaune très caractéristique.
La berbérine existe-t-elle en pharmacie ?
On en croise en pharmacie, mais presque toujours sous la forme classique. La dihydroberbérine brevetée, elle, reste l'apanage des marques de nutrition sportive : c'est un ingrédient de niche que l'on trouve dans les boutiques spécialisées.
Où trouver de la berbérine ?
Dans notre rayon berbérine, en ligne comme en magasin à Vendargues. Le Gluco-B y figure aux côtés du reste de la gamme Naughty Boy.
Où acheter le Gluco-B ?
Nous expédions dans toute la France et partout en Europe, avec un suivi sur chaque colis, et les commandes de la semaine partent le jour même dès que le stock le permet.
La boutique KISS NUTRITION est à Vendargues, à dix minutes de Montpellier : on vous montre le flacon, on lit l'étiquette ensemble et on répond aux questions sur la dihydroberbérine. Toute la marque est ici : Naughty Boy.
Qu'est-ce que la Berberine 1000 mg d'Applied Nutrition ?
La Berberine 1000 mg est la berbérine d'Applied Nutrition, sous forme de chlorhydrate titré à 97 % et issu de Berberis aristata, l'épine-vinette indienne.
La formule est courte : l'actif, un support, une enveloppe végétale et un seul ajout, l'AstraGin®. Le reste de la gamme est dans le rayon Applied Nutrition.
Ce qu'il y a dans la Berberine 1000 mg
Le chlorhydrate de berbérine titré à 97 % occupe l'essentiel de la gélule. C'est la forme la plus répandue de cet alcaloïde végétal, celle que l'on retrouve dans la grande majorité des compléments.
L'AstraGin® est le seul autre actif : un complexe breveté associant un extrait de racine d'astragale et un extrait de racine de Panax notoginseng.
L'enveloppe est en hypromellose, donc végétale : le produit convient aux végétaliens. Chaque lot est contrôlé dans le cadre d'un programme destiné aux sportifs.
À qui s'adresse la Berberine 1000 mg ?
À ceux qui connaissent déjà la berbérine et cherchent un titrage élevé plutôt qu'une poudre de plante. 97 %, c'est le haut du panier pour cet actif.
Elle s'adresse aussi à ceux qui veulent une formule sans rien autour : pas de mélange propriétaire, pas de dix actifs mélangés dont on ne connaît pas les quantités.
Comme toutes les gélules végétales de la marque, elle convient aux végétariens et aux végétaliens.
Questions fréquentes
Qu'est-ce que la berbérine ?
C'est un alcaloïde jaune présent dans plusieurs plantes, dont l'épine-vinette indienne. On la trouve en complément sous forme de chlorhydrate, sa forme la plus stable.
Qu'est-ce que Berberis aristata ?
C'est l'épine-vinette indienne, un arbuste dont l'écorce et les racines sont riches en berbérine. C'est la source utilisée ici.
Que veut dire « titré à 97 % » ?
Que la matière première contient 97 % de berbérine. Plus le titrage est élevé, moins il y a de matière végétale inerte dans la gélule.
Qu'est-ce qu'AstraGin® ?
C'est un complexe breveté associant un extrait de racine d'Astragalus membranaceus et un extrait de racine de Panax notoginseng. Applied Nutrition l'utilise dans plusieurs formules.
Les gélules sont-elles végétales ?
Oui. L'enveloppe est en hypromellose, une cellulose modifiée d'origine végétale, et le produit convient aux végétaliens.
Combien de gélules contient le flacon ?
Le flacon contient 60 gélules.
La berbérine existe-t-elle sous d'autres marques chez vous ?
Oui, le rayon Berbérine réunit toutes les références du catalogue qui en contiennent.
Où acheter la Berberine 1000 mg ?

Qu'est-ce que l'i-Drive d'Applied Nutrition ?
L'i-Drive d'Applied Nutrition est un complément en gélules organisé en trois complexes : Glyco-Load, Insu-Drive et Nutrient Uptake. Une portion correspond à deux gélules ; la boîte de 120 gélules couvre soixante portions.
La marque le présente comme le compagnon de ses gainers, à prendre autour des repas les plus riches en glucides. Le reste de la gamme est dans le rayon Applied Nutrition.
Ce qu'il y a dans l'i-Drive
Glyco-Load : extrait de melon amer (Momordica charantia, 10 % de principes amers), extrait d'écorce de cannelle de Ceylan (Cinnamomum verum, 10:1), extrait de figuier de Barbarie (Opuntia dillenii), extrait de graine de fenugrec (20 % de 4-hydroxyisoleucine), extrait de feuille de banaba (1 % d'acide corosolique minimum) et sel rose de l'Himalaya.
Insu-Drive : extrait de feuille de Gymnema sylvestre (75 % d'acides gymnémiques), acide alpha-lipoïque, berbérine et vitamine C.
Nutrient Uptake : extrait de racine de gingembre, BioPerine® (Piper nigrum, 95 % de pipérine minimum), vitamine B6, cuivre (gluconate de cuivre), picolinate de chrome et vitamine D3.
Le chrome contribue au métabolisme normal des macronutriments et au maintien d'une glycémie normale. La vitamine B6 contribue au métabolisme normal des protéines et du glycogène. Le cuivre et la vitamine C contribuent à la protection des cellules contre le stress oxydatif. La vitamine D contribue au maintien d'une fonction musculaire normale.
À qui s'adresse l'i-Drive ?
À ceux qui suivent une prise de masse avec des apports glucidiques élevés et veulent accompagner ces repas, plutôt qu'à ceux qui cherchent un brûleur ou un coupe-faim.
C'est une formule dense : dix-sept actifs, dont neuf extraits de plantes. Elle intéresse ceux qui préfèrent une seule boîte plutôt que d'acheter berbérine, cannelle et chrome séparément.
Questions fréquentes
Combien d'extraits de plantes contient la formule ?
Neuf, répartis dans les trois complexes : melon amer, cannelle de Ceylan, figuier de Barbarie, fenugrec, banaba, gymnema, gingembre, poivre noir et berbérine.
Combien de portions dans la boîte ?
Soixante : la boîte contient 120 gélules et une portion correspond à deux gélules.
Quels sont les trois complexes de la formule ?
Glyco-Load (melon amer, cannelle de Ceylan, figuier de Barbarie, fenugrec, banaba, sel rose), Insu-Drive (gymnema, acide alpha-lipoïque, berbérine, vitamine C) et Nutrient Uptake (gingembre, BioPerine®, vitamine B6, cuivre, chrome, vitamine D3).
Quel est le rôle reconnu du chrome ?
Le chrome contribue au métabolisme normal des macronutriments et au maintien d'une glycémie normale.

L'équipe du magasin de Vendargues, à dix minutes de Montpellier, répond aussi au téléphone. Toutes les références de la marque sont dans le rayon Applied Nutrition, et les autres sources de berbérine dans le rayon Berbérine.
What is berberine?
Berberine is a plant alkaloid belonging to the protoberberine family, an intensely yellow nitrogenous compound long used as a dye. It is neither a plant nor a whole plant extract: it is an isolated molecule, extracted and purified from several species that contain it.
The main sources are barberry (Berberis vulgaris), a European shrub, Coptis chinensis and Phellodendron amurense, long used in Chinese pharmacopoeia, goldenseal (Hydrastis canadensis) and greater celandine (Chelidonium majus). It concentrates in the roots, rhizomes, and bark, very little in the fruits — a distinction that has regulatory importance.
In the supplement market, it most often comes in the form of berberine hydrochloride, in capsules, with a standardized percentage. An extract standardized to 97% contains 97% pure berberine: it is a highly purified raw material, very different from a plant powder. Some formulas combine it with a trace element; the regulatory mentions on the packaging then concern this trace element, never berberine.
Why is its oral bioavailability so low?
This is the most documented characteristic of this molecule, and the one from which almost everything else follows. According to ANSES's evaluation, the oral bioavailability of berberine is less than 1%: out of the amount ingested, less than one hundredth reaches the general circulation in unchanged form.
Three mechanisms combine: inherently poor intestinal absorption; P-glycoprotein, an efflux pump in the intestinal wall, which returns part of the absorbed molecule to the digestive lumen; and significant intestinal and hepatic metabolism of what nonetheless crosses the barrier.
Two practical consequences. Most of the dose remains in the digestive tract, which explains the frequency of gastrointestinal issues described below. And this very low bioavailability greatly complicates the interpretation of published works: it makes it difficult to transpose observations made on cells or animals to humans, at concentrations irrelevant to what a human digestive tract allows through. So-called enhanced bioavailability formulations exist, but they are not standardized.
What doses are in circulation, and what should be made of them?
Here we describe what is available on the market, without recommending it. ANSES notes that food supplements offer daily doses between 250 and 1,200 mg of berberine. The agency makes a remark about them that should give pause: these doses are comparable to those that show documented pharmacological activity in clinical studies. An intake within this range is therefore not a supplementary dietary intake.
Fractionation is the usual practice: the daily dose is divided into two or three intakes during meals, as the molecule has a short half-life and better digestive tolerance this way. This is descriptive information, not prescriptive.
There is no maximum daily dose set in France. Belgium has set a ceiling of 10 mg per day for isoquinoline alkaloids, which ANSES considers not justified by available safety data at present — which does not mean that a higher ceiling would be: it means that data is lacking. This absence of a benchmark is in itself information: no one can give you a reference dose for this product, and we will not do so either. The quantity that concerns you, if any, is a matter for your doctor.
What drug interactions does berberine have?
This is the most important point on this page. Berberine inhibits cytochrome P450 3A4 (CYP3A4), the hepatic and intestinal enzyme that metabolizes a very large proportion of commonly used medications, and it inhibits P-glycoprotein, the transporter that conditions the absorption and elimination of many molecules. Inhibiting these two systems slows down the elimination of the drugs that depend on them: their blood concentrations increase, with a risk of overdose at unchanged dosage.
ANSES explicitly cites documented interactions with ciclosporin, tacrolimus, simvastatin, midazolam, digoxin, and dextromethorphan. Several of these medications have a narrow therapeutic window: the difference between the effective dose and the toxic dose is small, and a change in concentration is enough to cause problems.
The agency's recommendation is unambiguous: the consumption of food supplements containing berberine in combination with medication is not recommended, especially for drugs with a narrow therapeutic window. This statement concerns many more people than one might imagine: the list of CYP3A4 substrates extends far beyond the molecules cited. If you are taking any medication, even occasionally, talk to your doctor or pharmacist before considering this product. This is not a polite phrase at the bottom of the page; it is the practical conclusion of all that precedes.
What are the contraindications and side effects?
The contraindications noted by ANSES are formal and not open to interpretation. Berberine is not recommended for pregnant women, due to uterotonic effects and a risk of toxicity for the embryo and fetus, for breastfeeding women, as well as for infants, children, and adolescents. It is also not recommended for people with G6PD deficiency, due to a risk of hemolytic anemia.
The most commonly described side effects are digestive: diarrhea, nausea, abdominal pain, constipation. Consistent with the fact that most of the dose remains in the digestive tract, they are the primary reason for discontinuation. Headaches and dizziness, acute liver damage, and cardiac effects, including arrhythmias, are also reported.
ANSES's general conclusion deserves to be quoted as is: it is not possible to exclude a risk to human health linked to the consumption of food supplements containing berberine. Any unusual manifestation occurring after intake warrants immediate cessation of the product and medical advice.
What is the regulatory status of berberine?
The subject is fluid, and we prefer to explain it precisely rather than assert that "it is authorized." In France, the list of plants allowed in food supplements is set by a 2014 decree. Phellodendron amurense is explicitly listed there, for its bark. Other berberine-containing plants present on the French market are there through the mutual recognition procedure provided for by the 2006 decree relating to food supplements. As for purified berberine used as a substance, it is not covered by this decree: ANSES itself notes the presence of supplements containing it on the market, and points out that this requires clarification. In other words, the framework applicable to these products is not as clear as their widespread availability might suggest.
At the European level, a procedure is underway under Article 8 of Regulation (EC) No 1925/2006, the mechanism that allows the Commission to have a substance whose safety is questioned examined — a referral initiated by France. EFSA issued a draft opinion in January 2026 concluding that a safe intake level cannot be established for berberine and the plant preparations containing it, pointing to in vitro genotoxicity signals, rodent carcinogenicity data, cases of liver damage, and significant toxicological gaps. The public consultation ended in spring 2026; the final opinion and the Commission's decision — which could lead to inclusion in Annex III of the regulation, meaning a ban, restriction, or community surveillance period — have not yet occurred. The status of berberine is therefore subject to change, and we will update this page accordingly.
One point remains unchanged, however: no health claims are authorized in Europe for berberine. None. Anything attributed to it elsewhere falls under commercial discourse or the repetition of unverified articles.
What should you not expect from berberine?
Berberine is widely presented online as a natural alternative to certain treatments. We do not endorse this comparison, and we advise you to be wary of any seller who does. A food supplement is not a medication: it is not evaluated, dosed, or monitored according to the same rules, and it cannot replace any prescription. Interrupting or modifying a treatment in favor of a supplement is a dangerous decision, which only your treating physician should make.
What we can say about this molecule is stated above: its chemical nature, its botanical origin, its very low bioavailability, its interactions, its contraindications, and the uncertain state of its regulation. Nothing else. This page is the most cautious in our catalog, and deliberately so: for a product for which the European Food Safety Authority believes that no safe intake level can be established, this is the only tenable position. If you are considering this product, the first step is to talk to your doctor.
Frequently Asked Questions
What is berberine?
A bright yellow plant alkaloid, isolated and purified from the bark, roots, or rhizomes of certain plants. The important point in one sentence: it is not a plant powder, it is a pure molecule, most often sold as a hydrochloride standardized to 97%, and at daily doses comparable to those that show pharmacological activity in clinical studies. This is what distinguishes it from most plant extracts in our stores, and what justifies the level of caution on this page.
Which plant contains berberine, and is it found in food?
The main sources are barberry (Berberis vulgaris), Coptis chinensis, Phellodendron amurense, goldenseal, and greater celandine. Berberine concentrates in the roots, rhizomes, and bark — not in the fruits, and not in market vegetables. No common food provides a significant amount of it: it is a supplement substance, not a nutrient from a plate. This is also why comparisons with spices or culinary plants, sometimes made online, are meaningless.
What are the benefits of berberine?
No health claims are authorized in Europe for berberine, and we will therefore make none. The situation goes even further than with other plants in our catalog: EFSA issued a draft opinion in January 2026 concluding that a safe intake level cannot be established, and ANSES believes that a risk to human health cannot be excluded. For a product whose safety is subject to an ongoing European procedure, announcing a benefit would be doubly wrong. What we describe on this page is a molecule, its origin, its bioavailability, and its risks.
Can berberine replace metformin or a diabetes treatment?
No, and this question deserves the firmest answer in our entire catalog. A food supplement is not evaluated, dosed, or monitored like a medication, and none can replace a prescription. Stopping or reducing an antidiabetic treatment on your own initiative exposes you to serious complications, sometimes without prior symptoms. Added to this is a risk specific to this molecule: berberine inhibits CYP3A4 and P-glycoprotein, and ANSES explicitly advises against combining it with medication. In other words, it is both unsuitable for replacing a treatment and problematic alongside it. If you are concerned about your diabetes or if your treatment is not suitable, the right person to talk to is your treating doctor — not a sales page, including ours.
Does berberine make you lose weight?
No claim to that effect is authorized, and we have no data to confirm it. A useful clarification, however: the weight loss sometimes reported online is almost always accompanied by the most well-documented side effects of this molecule — diarrhea, nausea, abdominal pain — which are the mechanical consequence of the fact that less than 1% of the dose leaves the digestive tract. This is not a desirable effect. If your goal is weight loss, the weight loss section and, above all, serious support for diet and physical activity are infinitely better.
Is berberine authorized in France?
Supplements containing it are marketed in France, but purified berberine used as a substance is not explicitly covered by the decree regulating permitted plants, and a European procedure is underway. The framework is evolving.
Can it be taken with ongoing treatment?
ANSES advises against it, particularly for drugs with a narrow therapeutic window. The answer must come from your doctor or pharmacist, who alone know all of your treatments.
When and how to take berberine?
We describe observed use, without recommending it: the daily dose is generally divided into two or three intakes spread during meals, as the molecule has a short half-life and better digestive tolerance this way. No specific time is established as superior to another, and no maximum daily dose is set in France — this void is not freedom, it is a shortcoming. The only instruction we take responsibility for: do not exceed the dose on the label, do not combine several products containing it, and talk about the product with your doctor before the first intake.
Why does it cause so many digestive problems?
Because less than 1% of the dose passes into the bloodstream: almost all of it remains in the digestive tract. Diarrhea, nausea, abdominal pain, and constipation are the most frequently reported side effects.
Can it be taken continuously?
Long-term safety data is insufficient, and this is precisely one of the reasons for the ongoing European procedure. This question is a matter for a healthcare professional, not for free use.
Is organic berberine available?
The organic mention may concern the cultivation of the source plant. It does not change the bioavailability of the molecule, its interactions, or its regulatory status. An organic extract is not a safer extract.
What are online reviews worth?
Very little on this specific subject. An individual testimony does not provide information on drug interactions or liver damage, which can be silent. For berberine more than for any other product, reviews do not replace medical advice.
Where to buy berberine?
On this page, with shipping throughout France and Europe, or in our store in Vendargues, about ten minutes from Montpellier. We deliberately list few products in this category, and we prefer to see you in store for this particular product: it's an opportunity to check together the standardization and quantity per capsule, and especially to ask you if you are undergoing treatment. If so, we will refer you to your doctor or pharmacist rather than selling you anything.
What can be found in this section?
We list few products in this category, and deliberately so. Our requirement focuses on label readability: botanical species of origin, chemical form, precise standardization, quantity per capsule, identified manufacturer, explicitly present precaution mentions. IO Genix offers a high-standardization formula meeting these criteria.
If you are looking for a common supplement, better documented and without this level of precautions, orient yourself instead towards omega 3, vitamin D, magnesium or multivitamins, a much more solid micronutrition foundation. Among plant extracts, turmeric, ashwagandha and spirulina have a more stable framework, and probiotics follow a different logic. The entire catalog starts from the sports nutrition section, and our complete guide to sports nutrition positions each product family.
Advice on berberine near Montpellier?
Our store in Vendargues, about ten minutes from Montpellier, is where we will verbally reiterate what this page says: read the label, check the standardization, and talk about this product with your doctor before touching it, especially if you are undergoing treatment. We also ship everywhere in France and Europe. We will tell you what a product contains; we will never tell you that it replaces anything.

What is berberine?
Berberine is a plant alkaloid belonging to the protoberberine family, an intensely yellow nitrogenous compound long used as a dye. It is neither a plant nor a whole plant extract: it is an isolated molecule, extracted and purified from several species that contain it.
The main sources are barberry (Berberis vulgaris), a European shrub, Coptis chinensis and Phellodendron amurense, long used in Chinese pharmacopoeia, goldenseal (Hydrastis canadensis) and greater celandine (Chelidonium majus). It concentrates in the roots, rhizomes, and bark, very little in the fruits — a distinction that has regulatory importance.
In the supplement market, it most often comes in the form of berberine hydrochloride, in capsules, with a standardized percentage. An extract standardized to 97% contains 97% pure berberine: it is a highly purified raw material, very different from a plant powder. Some formulas combine it with a trace element; the regulatory mentions on the packaging then concern this trace element, never berberine.
Why is its oral bioavailability so low?
This is the most documented characteristic of this molecule, and the one from which almost everything else follows. According to ANSES's evaluation, the oral bioavailability of berberine is less than 1%: out of the amount ingested, less than one hundredth reaches the general circulation in unchanged form.
Three mechanisms combine: inherently poor intestinal absorption; P-glycoprotein, an efflux pump in the intestinal wall, which returns part of the absorbed molecule to the digestive lumen; and significant intestinal and hepatic metabolism of what nonetheless crosses the barrier.
Two practical consequences. Most of the dose remains in the digestive tract, which explains the frequency of gastrointestinal issues described below. And this very low bioavailability greatly complicates the interpretation of published works: it makes it difficult to transpose observations made on cells or animals to humans, at concentrations irrelevant to what a human digestive tract allows through. So-called enhanced bioavailability formulations exist, but they are not standardized.
What doses are in circulation, and what should be made of them?
Here we describe what is available on the market, without recommending it. ANSES notes that food supplements offer daily doses between 250 and 1,200 mg of berberine. The agency makes a remark about them that should give pause: these doses are comparable to those that show documented pharmacological activity in clinical studies. An intake within this range is therefore not a supplementary dietary intake.
Fractionation is the usual practice: the daily dose is divided into two or three intakes during meals, as the molecule has a short half-life and better digestive tolerance this way. This is descriptive information, not prescriptive.
There is no maximum daily dose set in France. Belgium has set a ceiling of 10 mg per day for isoquinoline alkaloids, which ANSES considers not justified by available safety data at present — which does not mean that a higher ceiling would be: it means that data is lacking. This absence of a benchmark is in itself information: no one can give you a reference dose for this product, and we will not do so either. The quantity that concerns you, if any, is a matter for your doctor.

This is the most important point on this page. Berberine inhibits cytochrome P450 3A4 (CYP3A4), the hepatic and intestinal enzyme that metabolizes a very large proportion of commonly used medications, and it inhibits P-glycoprotein, the transporter that conditions the absorption and elimination of many molecules. Inhibiting these two systems slows down the elimination of the drugs that depend on them: their blood concentrations increase, with a risk of overdose at unchanged dosage.

Questions fréquentes — Berberine
La berbérine, c'est quoi ?
Un alcaloïde végétal jaune vif, isolé et purifié à partir de l'écorce, des racines ou des rhizomes de certaines plantes. Le point important tient en une phrase : ce n'est pas une poudre de plante, c'est une molécule pure, vendue le plus souvent sous forme de chlorhydrate titré à 97 %, et à des doses journalières comparables à celles qui présentent une activité pharmacologique dans les études cliniques. C'est ce qui la distingue de la plupart des extraits végétaux de nos rayons, et ce qui justifie le niveau de précaution de cette page.
Quelle plante contient de la berbérine, et en trouve-t-on dans l'alimentation ?
Les sources principales sont l'épine-vinette (Berberis vulgaris), le Coptis chinensis, le Phellodendron amurense, l'hydraste du Canada et la grande chélidoine. La berbérine s'y concentre dans les racines, les rhizomes et les écorces — pas dans les fruits. Aucun aliment courant n'en apporte de quantité significative : c'est une substance de complément, pas un nutriment de l'assiette.
Que peut-on dire de la berbérine ?
Aucune allégation de santé n'est autorisée en Europe pour la berbérine, et nous n'en formulons donc aucune. La situation va même plus loin : l'EFSA a rendu en janvier 2026 un projet d'avis concluant qu'un niveau d'apport sûr ne peut pas être établi, et l'ANSES estime qu'un risque pour la santé humaine ne peut pas être exclu. Ce que nous décrivons sur cette page, c'est donc une molécule, son origine, sa biodisponibilité et ses précautions.
La berbérine peut-elle remplacer la metformine ou un traitement contre le diabète ?
Non. Un complément alimentaire n'est ni évalué, ni dosé, ni surveillé comme un médicament, et aucun ne peut se substituer à une prescription. Arrêter ou réduire un traitement antidiabétique de sa propre initiative expose à des complications graves, parfois sans symptôme préalable. S'y ajoute un point propre à cette molécule : la berbérine inhibe le CYP3A4 et la P-glycoprotéine, et l'ANSES déconseille expressément de l'associer à un traitement médicamenteux. Si votre diabète vous inquiète ou si votre traitement vous convient mal, l'avis du médecin qui vous suit reste la référence.
Que sait-on de la berbérine et du poids ?
Aucune allégation en ce sens n'est autorisée, et nous n'en formulons aucune. Une précision utile : les effets digestifs les mieux documentés de cette molécule — diarrhées, nausées, douleurs abdominales — sont la conséquence mécanique du fait que moins de 1 % de la dose quitte le tube digestif. Si votre objectif est la perte de poids, notre rayon perte de poids et un accompagnement sur l'alimentation et l'activité physique répondent directement au besoin.
La berbérine est-elle autorisée en France ?
Des compléments en contenant sont commercialisés en France, mais la berbérine purifiée employée comme substance n'est pas explicitement visée par l'arrêté encadrant les plantes admises, et une procédure européenne est en cours. Le cadre est en évolution.
Peut-on en prendre avec un traitement en cours ?
L'ANSES le déconseille, en particulier pour les médicaments à marge thérapeutique étroite. La réponse vient de votre médecin, seul à connaître l'ensemble de vos traitements.
Quand et comment prendre la berbérine ?
Nous décrivons l'usage constaté : la dose journalière est généralement fractionnée en deux ou trois prises réparties au cours des repas, la molécule ayant une demi-vie courte et une tolérance digestive meilleure ainsi. Aucun horaire n'est établi comme supérieur à un autre, et aucune dose journalière maximale n'est fixée en France. Les consignes que nous assumons : ne pas dépasser la dose de l'étiquette, ne pas cumuler plusieurs produits en contenant, et parler du produit à votre médecin avant la première prise.
Pourquoi provoque-t-elle autant de troubles digestifs ?
Parce que moins de 1 % de la dose passe dans la circulation : la quasi-totalité reste dans le tube digestif. Diarrhées, nausées, douleurs abdominales et constipation sont les effets indésirables les plus fréquemment rapportés.
Peut-on en prendre en continu ?
Les données de sécurité au long cours sont insuffisantes, et c'est précisément l'un des motifs de la procédure européenne en cours. Cette question relève d'un professionnel de santé.
Existe-t-il de la berbérine bio ?
La mention biologique peut concerner la culture de la plante source. Elle ne change ni la biodisponibilité de la molécule, ni ses interactions, ni son statut réglementaire.
Que valent les avis publiés en ligne ?
Peu de chose sur ce sujet précis. Un témoignage individuel ne renseigne ni sur une interaction médicamenteuse, ni sur une atteinte hépatique, qui peuvent être silencieuses. Sur la berbérine, l'avis de votre médecin reste la référence.
Où acheter de la berbérine ?
Sur cette page, avec expédition partout en France et en Europe, ou dans notre boutique de Vendargues, à une dizaine de minutes de Montpellier. Nous référençons volontairement peu sur cette catégorie, et nous préférons vous voir en magasin pour ce produit-là : c'est l'occasion de vérifier ensemble le titrage et la quantité par gélule, et de faire le point sur un éventuel traitement en cours.
