L glutamine is the most abundant amino acid found in human muscle and plasma. Over 60% of the free-floating amino acid pool in skeletal muscle cells is made up of L glutamine. It prevents your muscle from being catabolized (eaten up) in order to provide Glutamine for other cells in the body. In times of physical stress, such as intense exercise, the body requires more of it to maintain its glutamine stores in blood and muscle. Glutamine may serve to boost your immune system. When glutamine stores are depleted, you may experience decreases in strength, stamina, and recovery. It's a carbon and nitrogen donor and helps restore glycogen which restores energy.
