The body makes it itself, which makes it a non-essential amino acid in the strict sense, but the rate at which it is used up rises during periods of sustained training, calorie restriction or physiological stress. That is where the question of an additional intake arises.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eKyowa Quality\u003c\/strong\u003e mention refers to the raw material, produced by Japan's Kyowa Hakko from a plant-based fermentation. It is an indication of origin and process, not a particular biological property: the molecule obtained is the same as that of any other glutamine. What the label guarantees is traceability and process control, which is no small thing on an amino acid produced in very large volumes.

One inconsistency deserves to be flagged rather than glossed over: \u003cstrong\u003ethe data sheet states 0 g of carbohydrate while the ingredients list mentions maltodextrin\u003c\/strong\u003e, which is one. The amount is in all likelihood small, but we do not know it and will not reconstruct it. The label on the tub you receive is the authority.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e5 g per serving is the reference amount\u003c\/strong\u003e, and it is the one used in most of the published work on glutamine. Few products go below it, but many sell 3 g scoops that then have to be doubled, which completely changes the real cost per serving. Always check the weight of the scoop before comparing two tubs.\u003c\/p\u003e\n\u003cp\u003eThe number of servings depends on the size, and there is a clarification to make here too. The manufacturer states 100 servings per container, which corresponds to the 500 g size. \u003cstrong\u003eThe 300 g size contains 60\u003c\/strong\u003e, at 5 g per serving. The larger size therefore works out cheaper per serving, but is only worth it if you keep it up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVitamin B6 at 1.4 mg\u003c\/strong\u003e covers the European reference value exactly. It is not there by chance: it contributes to normal protein and glycogen metabolism, to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. It is the only ingredient in this tub to carry authorised claims. If it is this vitamin that interests you in its own right, our \u003ca href=\"\/en\/collections\/vitamine-b\"\u003evitamin B\u003c\/a\u003e aisle offers it dosed separately.\u003c\/p\u003e\n\u003cp\u003eA regulatory clarification belongs here: \u003cstrong\u003eL-glutamine has no authorised health claim in Europe\u003c\/strong\u003e. Not on recovery, not on immunity, not on the gut lining. The former description on this page claimed that supplementation sped up recovery and maintained immune function: that wording was not compliant and has been removed.\u003c\/p\u003e\n\n\u003ch4\u003eIngredients list\u003c\/h4\u003e\n\u003cp\u003eL-glutamine (Kyowa Quality), maltodextrin, acidity regulator (citric acid), flavouring, sweeteners (sucralose and acesulfame K) and vitamin B6 (pyridoxine hydrochloride). The unflavoured version contains neither flavouring nor sweetener. \u003cstrong\u003eMay contain traces of GLUTEN, EGGS, FISH, SOYA and MILK.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eHow do you take Glutamine Kyowa?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eServing:\u003c\/strong\u003e one level scoop, or 5 g. \u003cstrong\u003eLiquid:\u003c\/strong\u003e 300 ml of water or fruit juice. \u003cstrong\u003eTiming:\u003c\/strong\u003e straight after training, or before bed on rest days. \u003cstrong\u003eFrequency:\u003c\/strong\u003e one serving per training day; the manufacturer describes a more intensive protocol of three servings spread across non-training days. \u003cstrong\u003eDuration:\u003c\/strong\u003e no set course length, use is ongoing.\u003c\/p\u003e\n\u003cp\u003eOne serving a day covers what the vast majority of trainees need. The three-serving protocol is aimed at high training volumes, and you should be clear about what it represents: 15 g of free amino acid a day, every day. If you are starting out, begin with one serving and see.\u003c\/p\u003e\n\u003cp\u003eThe powder dissolves well but stays slightly tart on the palate in the raspberry version. Fruit juice masks that tartness better than water does, with no downside. The unflavoured version, for its part, mixes into anything — into a \u003ca href=\"\/en\/collections\/proteines\"\u003eprotein\u003c\/a\u003e shake, into porridge, into a fruit purée — and it is often the more practical choice for everyday use.\u003c\/p\u003e\n\u003cp\u003eAvoid mixing it into a hot drink: glutamine is not very stable in solution when heated. A shake made up in the morning for the afternoon is no problem; a cup of boiling tea is.\u003c\/p\u003e\n\n\u003ch2\u003eWho is Glutamine Kyowa for, and who is it not for?\u003c\/h2\u003e\n\u003cp\u003eIt suits someone on a high training volume, someone in a prolonged calorie deficit, or someone stringing sessions together without a genuine rest day. Those are the situations in which the body's use of glutamine rises the most.\u003c\/p\u003e\n\u003cp\u003eThe manufacturer does not recommend it for \u003cstrong\u003epregnant and breastfeeding women\u003c\/strong\u003e and restricts it to \u003cstrong\u003eadults over 18\u003c\/strong\u003e. It also asks that you seek the advice of a healthcare professional in cases of liver or kidney disorders, or if you are on medication: that is a sensible precaution, since amino acid metabolism runs through the liver and the kidneys.\u003c\/p\u003e\n\u003cp\u003eIt is not for you if your daily protein intake is already high. This is the least commercial truth on this page: a 30 g \u003ca href=\"\/en\/collections\/whey-isolate-1\"\u003ewhey isolate\u003c\/a\u003e shake already supplies roughly 1.5 to 2 g of glutamine, and a diet providing 150 g of protein a day supplies several grams. In that context, the additional intake is marginal, and the literature on the benefits of supplementation in a well-fed athlete is far from convincing.\u003c\/p\u003e\n\u003cp\u003eWhat you should not expect from it: this is not a product that drives progress. It does not build muscle, it does not replace a protein, and you will feel nothing when you take it. It is a comfort supplement, to consider once the rest is already in place, not before. If you have any medical doubt, ask your doctor or your pharmacist.\u003c\/p\u003e\n\n\u003ch2\u003eGlutamine or EAAs after training?\u003c\/h2\u003e\n\u003cp\u003eBoth are taken at the same moment and compete for the same budget, so we may as well put the question plainly.\u003c\/p\u003e\n\u003cp\u003eAn \u003ca href=\"\/en\/collections\/eaa\"\u003eEAA\u003c\/a\u003e supplies all nine essential amino acids, including the leucine that triggers protein synthesis. In terms of building muscle, there is no comparison: it is the better choice if you train fasted, if your protein intake is low, or if you want a single product after the session. It costs more per serving, and it has a stronger taste.\u003c\/p\u003e\n\u003cp\u003eGlutamine does not play in that category. Its value lies elsewhere: it is a non-essential amino acid, heavily used during periods of heavy load, and its use has more to do with recovery comfort than with performance. It is the better choice if your diet already comfortably covers your protein needs and you are looking to top up on one specific point, or if you cope badly with complex formulas.\u003c\/p\u003e\n\u003cp\u003eIf your budget allows only one product, buy the protein or the \u003ca href=\"\/en\/collections\/bcaa-eaa\"\u003eessential amino acids\u003c\/a\u003e before the glutamine. That is the logical order, and we say so over the counter just as we do here.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eHow many servings are in a tub?\u003c\/h3\u003e\n\u003cp\u003eSixty for the 300 g size, one hundred for the 500 g size, at 5 g per serving. The manufacturer quotes the figure of 100 servings without specifying which size it refers to: it corresponds to the 500 g. The larger size works out cheaper per serving if you keep it up.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the unflavoured and raspberry versions?\u003c\/h3\u003e\n\u003cp\u003eThe active ingredient make-up is identical. The raspberry version additionally contains a flavouring, an acidity regulator and sweeteners; the unflavoured version contains none. The unflavoured one mixes into anything without disturbing the taste, the raspberry one is more pleasant drunk on its own. That is the only deciding factor.\u003c\/p\u003e\n\u003ch3\u003eWhen should you take it?\u003c\/h3\u003e\n\u003cp\u003eStraight after training on session days, before bed on rest days. Timing matters less than consistency: glutamine acts on a body pool that rebuilds slowly, not on a one-off peak. One serving a day at a set time is worth more than three irregular ones.\u003c\/p\u003e\n\u003ch3\u003eShould you take it if you already use whey?\u003c\/h3\u003e\n\u003cp\u003eThe benefit becomes slight. A 30 g whey serving already supplies a far from negligible share of glutamine, and a protein-rich diet supplies several grams a day. Supplementation still makes sense during a period of unusual load or a marked calorie deficit, less so in an ordinary situation.\u003c\/p\u003e\n\u003ch3\u003eCan it be mixed into a hot drink?\u003c\/h3\u003e\n\u003cp\u003eBetter to avoid it. Glutamine is not very stable in solution at high temperature and partly degrades. Mixing it into cold or lukewarm water, or into a juice, poses no problem at all, including when made up a few hours in advance.\u003c\/p\u003e\n\u003ch3\u003eIs glutamine suitable for vegans?\u003c\/h3\u003e\n\u003cp\u003eThe Kyowa Quality raw material is obtained by fermentation of plant origin, with no animal input, as the manufacturer states. The point to watch is the declared manufacturing traces — gluten, eggs, fish, soya and milk — which come from the production environment and not from the formula.\u003c\/p\u003e\n\u003ch3\u003eWhy is there vitamin B6 in a glutamine?\u003c\/h3\u003e\n\u003cp\u003eBecause B6 is involved in amino acid metabolism, and because it is the only ingredient in this tub for which a claim is authorised in Europe. At 1.4 mg, it covers the daily reference value exactly. If you already take a multivitamin, be aware that stacking the two carries no risk at this level.\u003c\/p\u003e\n\n\u003ch2\u003eWhere can you buy IO Genix Glutamine Kyowa?\u003c\/h2\u003e\n\u003cp\u003eThe sizes and versions can be ordered from this page, and we ship throughout France and Europe.
