During intense training Glutamine levels are greatly depleted in your body which decreases strength stamina and recovery It could take up to 6 days for Glutamine levels to return to normal if not supplemented. Glutamine has been linked to protein synthesis. It prevents your muscle from being catabolized (eaten up) in order to provide Glutamine for other cells in the body. Glutamine helps maintain cell volume and hydration speeding up wound and burn healing and recovery. Glutamine benefits you by replenishing declining Glutamine levels during intense workouts.
