Glutamine is the most abundant amino acid in tissues and the blood.1 It is important as an energy source and as a precursor to gluta-thione. Glutamine can be taken up by the brain and converted to gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter.

Energy metabolism. Glutamine is broken down to produce energy in many tissues in the body. It is especially important as an energy source for the cells lining the digestive tract and the white blood cells. Glutamine can be taken up by the liver and converted to glucose to maintain blood sugar levels.2
Glutathione synthesis. Glutamine, together with cysteine, serves as the precursor in the synthesis of glutathione, an important antioxidant1 (see pp.105).
Conversion to GABA. Glutamine is readily taken up by the brain and converted to GABA. GABA is an important inhibitory neurotransmitter with tranquilizing, calming effects.3 Valium and other benzodiazepine drugs exert their calming effects by enhancing the actions of GABA in the brain.
