What is L-glutamine?

Glutamine is a nonessential amino acid. Glutamine can donate the ammonia on its side chain to the formation of urea (for eventual excretion by the kidneys) and to purines (necessary for the synthesis of nucleic acids). Glutamic acid-to-glutamine conversion, in which an ammonia group is added to glutamic acid (catalyzed by glutamine synthase), is of central importance in the regulation of toxic levels of ammonia in the body. This agent is a substrate for the production of both excitatory and inhibitory neurotransmitters (glutamate and GABA) and is also an important source of energy for the nervous system. Glutamine may become a conditionally essential amino acid during certain catabolic states.

L-glutamine is an essential amino acid and precursor of major intracellular antioxidant molecules that is used in high doses to prevent vaso-occlusive crises in patients with sickle cell disease. L-glutamine has not been associated with serum enzyme elevations during therapy or to instances of idiosyncratic acute liver injury.
