Glutamine is a very important amino acid, essential for the preservation of lean muscle tissue, for the formation of the antioxidant glutathione, and for the production of neurotransmitters such as glutamate and GABA (gamma amino butyric acid).

In these times, glutamine becomes a 'conditionally essential amino acid' and must be provided exogenously to meet physiologic needs.
