Glutamine

Glutamine is the most abundant amino acid in the human body. In fact, 60% of the free amino acid pool in the muscles is made up of glutamine indicating its significance. In stress situations, such as during and after an intense training session, the body requires so much glutamine that not enough can be synthesized so it becomes a conditionally essential amino acid. Besides your muscles, the gastro-intestinal tract and the immune system use up a lot of glutamine as a source of energy and for nucleotide production.

Glutamine is the single most abundant free amino acid in the body and the greatest pool of it tends to be found in muscle. As one of the most important amino acids in the body, it plays a direct role in building lean muscle tissue
