Glutamine POWDER

Glutamine POWDER is the Yamamoto Nutrition supplement containing pure L-Glutamine powder, obtained from plant fermentation processes.
Glutamine POWDER is suitable for athletes who practise physical activities requiring intense muscle exertion.

Glutamine is a conditionally essential amino acid for the body, and is concentrated particularly in muscle tissue. It is essential for the nervous system, is crucial for digestive processes and is an important intermediate for kidney and liver function. Precisely because of its high availability in the body, L-glutamine performs multiple functions and our body also uses it as needed, transforming it, for example, into another amino acid depending on the demands and needs of the various tissues. Under normal conditions, glutamine is synthesised by the body mainly in the skeletal muscle and, to a lesser extent, in the liver, brain and lungs.

Glutamine has several functions: it helps prevent muscle catabolism, promotes nutrient absorption in the intestines when the body is under intense strain and can provide an alternative source of energy. Precisely because of its contribution to intestinal health, glutamine has re-emerged in the fitness and supplementation market in recent years: given the ever-increasing incidence of intestinal and digestive stress, it is useful also in the mass phase to maintain intestinal health, which is put at risk by high calorie intakes.

It also appears to play a role in delaying fatigue by promoting glycogen synthesis and reducing ammonia build-up, while avoiding raising insulin levels in any way. Muscle glycogen is essential for exercise and good performance during training, and taking glutamine is useful in this regard, especially during periods of low-carbohydrate diets or in the definition phase. It facilitates muscle recovery particularly in men and supports cell hydration. It is a safe supplement even when taken for prolonged periods. Recent studies suggest a post-workout intake of 8 g of Glutamine per day, when taken for glycogen re-synthesis, while quantities of approximately 20 g/day are indicated when used for anti-catabolic purposes, when it should be taken post-workout or split into several servings throughout the day.
