The body can manufacture it, which places it among the non-essential amino acids, and an ordinary diet already supplies appreciable amounts: dairy products, meat, fish, eggs and pulses all contain it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe term “free” form means that the amino acid is not bound to any other: it is ready to be absorbed as it is\u003c\/strong\u003e, which explains why it dissolves instantly in water.

These values cannot all be correct at once; we would rather not reproduce them than publish figures that do not add up.

The dossiers submitted did not succeed. So we describe an amino acid, its dosage and how to use it, without promising any result.\u003c\/p\u003e\n\u003cp\u003eWe need to go further, because that is our job as a retailer. \u003cstrong\u003eIn a healthy athlete who eats enough protein, the available research shows no notable effect of glutamine supplementation on muscle mass or performance.\u003c\/strong\u003e An adequate protein intake already supplies glutamine in quantity — a whey provides several grams per serving without it having to be stated on the label. The uses where glutamine has a documented benefit belong to the clinical field, under medical supervision, and not to sports nutrition.\u003c\/p\u003e\n\u003cp\u003eWhat does remain true: this is a pure powder, dosable to the gram, additive-free, reasonably priced and perfectly well tolerated by most people. If you want to try it knowing exactly what it is, it is a clean product.

Shake for five seconds and drink: it has no pronounced taste, barely a slight bitterness. It therefore mixes without difficulty into a protein shake, a juice or a training drink.\u003c\/p\u003e\n\u003cp\u003eThe manufacturer recommends taking it away from meals to aid absorption, as glutamine shares its intestinal transporters with other amino acids. In practice, taking it straight after the session or between two meals meets that condition effortlessly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIf you have a sensitive stomach, start at 5 g per serving before moving up to 10 g.\u003c\/strong\u003e That is the manufacturer's advice, and it is justified: free amino acids at high doses sometimes cause temporary digestive discomfort in the first few days. Do not exceed the stated amounts in the belief that more is better, as it would achieve nothing.\u003c\/p\u003e\n\u003cp\u003eIt combines without redundancy with a \u003ca href=\"\/en\/collections\/proteines\"\u003eprotein\u003c\/a\u003e, with \u003ca href=\"\/en\/collections\/eaa\"\u003eEAAs\u003c\/a\u003e or with \u003ca href=\"\/en\/collections\/creatine-1\"\u003ecreatine monohydrate\u003c\/a\u003e. Simply note that a whey already supplies you with glutamine, which makes the addition less decisive than is often claimed.\u003c\/p\u003e\n\n\u003ch2\u003eWho is Core L-Glutamine for, and who is it not for?\u003c\/h2\u003e\n\u003cp\u003eIt suits an adult who wants a pure, additive-free powder and who knows the limits of the product. The format is perfectly clean: a single ingredient, precisely dosable, suitable for vegan diets.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe manufacturer recommends medical advice in the event of liver or kidney disease.\u003c\/strong\u003e This is not a token precaution: both organs are directly involved in amino acid metabolism, and the question cannot be settled over the counter. The manufacturer also flags possible drug interactions: if you are on any medication, discuss it with your doctor or pharmacist.\u003c\/p\u003e\n\u003cp\u003eIt is not recommended for pregnant or breastfeeding women without the advice of a healthcare professional.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat you should not expect from it, and we say so bluntly because it is the most useful information on this page.\u003c\/strong\u003e It does not build muscle. It does not speed up recovery in any demonstrated way in a healthy athlete. It does not boost immunity — no claim of that kind is authorised. If your daily protein intake is adequate, you are already consuming glutamine in quantity without knowing it. This product makes up for neither poorly designed training, nor insufficient sleep, nor a diet that is too sparse.\u003c\/p\u003e\n\n\u003ch2\u003eGlutamine or protein powder?\u003c\/h2\u003e\n\u003cp\u003eThis is the honest comparison to make before buying, and it comes down fairly clearly in favour of the latter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA serving of whey supplies 20 to 25 g of complete protein, including several grams of naturally occurring glutamine\u003c\/strong\u003e, plus the full set of essential amino acids the body cannot manufacture. And protein does have authorised claims: \u003cstrong\u003eprotein contributes to a growth in and the maintenance of muscle mass\u003c\/strong\u003e. On cost per serving, there is no comparison. Our \u003ca href=\"\/en\/collections\/whey-isolate-1\"\u003ewhey isolate\u003c\/a\u003e section is the first place to look if your goal is muscle mass.\u003c\/p\u003e\n\u003cp\u003eIsolated glutamine does something else: it supplies a single amino acid, in large amounts, without the others. That is useful when you are specifically after this molecule, for a use documented elsewhere or on the advice of a healthcare professional.\u003c\/p\u003e\n\u003cp\u003eWhen is glutamine the better choice? When you know why you are taking it and are not counting on it to progress in training. If your aim is to cover your amino acid needs around the session, \u003ca href=\"\/en\/collections\/bcaa-eaa\"\u003eBCAAs\u003c\/a\u003e and above all EAAs make more sense, and a complete protein makes more sense still.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eHow much glutamine per serving?\u003c\/h3\u003e\n\u003cp\u003e10 g of pure L-glutamine per scoop, for 30 kcal. The powder analyses at 100 g of protein per 100 g: there is nothing else in it. For intensive use, the manufacturer provides for 15 g split into 5 g before and 10 g after the session.\u003c\/p\u003e\n\u003ch3\u003eDoes glutamine really help you recover?\u003c\/h3\u003e\n\u003cp\u003eNo recovery claim is authorised in Europe for glutamine, and in a healthy athlete who eats enough protein, the available research shows no notable effect. It is a clean product, but we will not promise you what has not been demonstrated.\u003c\/p\u003e\n\u003ch3\u003eWhen should you take it?\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer settles on the fifteen minutes following training, or a serving between two meals, or else before bed. The common thinking is to take it away from a meal, as glutamine shares its intestinal transporters with other amino acids.\u003c\/p\u003e\n\u003ch3\u003eWhat does this powder taste like?\u003c\/h3\u003e\n\u003cp\u003eAlmost nothing, barely a slight bitterness. It is neither flavoured nor sweetened. It dissolves instantly in cold water, with no lumps or sediment, which makes it easy to add to a protein shake or a juice.\u003c\/p\u003e\n\u003ch3\u003eDoes a whey already contain some?\u003c\/h3\u003e\n\u003cp\u003eYes, several grams per serving, without this always appearing on the label. It is a point few retailers mention: if you already take a protein powder every day, your glutamine intake is far from nil.\u003c\/p\u003e\n\u003ch3\u003eWhat should you do about digestive discomfort?\u003c\/h3\u003e\n\u003cp\u003eDrop to 5 g per serving, as the manufacturer provides for, and build back up gradually. The discomfort mainly concerns the first few days and high doses of free amino acids. Taking the powder with a little more water also helps.\u003c\/p\u003e\n\u003ch3\u003eIs this powder suitable for vegans?\u003c\/h3\u003e\n\u003cp\u003eYes. The L-glutamine is obtained by plant-based fermentation, with no raw material of animal origin, and the manufacturer declares the product vegan, halal, gluten-free, lactose-free and soya-free.\u003c\/p\u003e\n\n\u003ch2\u003eWhere can you buy Sinob Core L-Glutamine?\u003c\/h2\u003e\n\u003cp\u003eThe tub can be ordered from this page, and we ship throughout France and Europe. At the Vendargues shop, about ten minutes from Montpellier, it is a product we are happy to sell but rarely recommend first: when a customer comes in looking for glutamine to make progress, we start by looking at what they eat and what protein they already take.
