GLUTAMINE is important in a number of metabolic processes related to muscle recovery and exercise, so it has been used as a nutritional supplement for bodybuilders and athletes looking to gain muscle size and strength. Glutamine has been linked to protein synthesis. It prevents your muscle from being catabolized (eaten up). Glutamine helps maintain cell volume and hydration, and recovery. Glutamine supplementation benefits you by replenishing declining Glutamine levels during intense workouts.
