L-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. L-Glutamine has been linked to protein synthesis. It prevents your muscle from being catabolised (eaten up). L-Glutamine helps maintain cell volume and hydration, and recovery.
L-Glutamine supplementation benefits you by replenishing declining L-Glutamine levels during intense workouts.
