The most abundant amino acid found in muscle cells, L-Glutamine, is recognized as an important anticatabolic agent. Naturally released by the body during muscle stress, Glutamine protects muscle from destructive breakdown by inhibiting the glutamine synthetase enzyme and neutralizing the muscle breakdown induced by cortisol. By drawing water into the muscle cell, Glutamine acts as a cell-hydrating agent which increases muscle cell volume. As an added benefit, when the muscle cells are filled with water, the muscles look bigger. When cells are well-hydrated, they reduce the amount of protein breakdown and promote an increase in protein and glycogen synthesis in the skeletal muscle; thereby, increasing the building of new muscle tissue.
