Catabolism is the break down of muscle mass that frequently occurs during bodybuilding. The anti-catabolic properties of glutamine prevent muscle breakdown. This amino acid plays a key role in the biochemical processes of protein synthesis and the fluid content within the cells. This is beneficial for people trying to get rid of body fat without losing muscle mass. Depletion of glutamine takes place during workouts and bodybuilders are prone to illness. It could take a number of days before a natural replenishment of this amino acid is achieved. L-Glutamine is important for balancing its levels during workouts. This supplement aids in quick recovery after strenuous training. The whole body requires glutamine for high-grade performance.
