Glutamine is an amino acid found in the muscles. It is also known as brain fuel because it easily passes the blood-brain barrier. Glutamine increases the amount of Gamma-Aminobutyric Acid (GABA), another amino acid that acts as a neurotransmitter in the central nervous system.
Glutamine helps to build and maintain muscle. It may be useful to bodybuilders, people recovering from injury or surgery, and may help to prevent muscle wasting from prolonged bed rest.
This amino acid may help reduce cravings for sugar and alcohol. Glutamine may also benefit epilepsy, fatigue, ulcers, impotence, senility, fatigue, arthritis, scleroderma (an autoimmune disorder that affects blood vessels and connective tissue), and polymyositis (multiple muscle inflammation).
Stress, prolonged illness, strenuous exercise, and surgery may deplete the body's reserves of glutamine.
Sources of Glutamine
Foods, including meat, milk, soy proteins, raw spinach and parsley are sources of glutamine. Cooking destroys glutamine. As a supplement, it is available in some multivitamin formulations, and individually in liquid, tablet/capsule (500-mg), and powder forms.
There is no recommended dietary requirement for glutamine. It is advised to take glutamine on an empty stomach before breakfast or between meals. Combining with zinc, and vitamins A, C, and E may enhance the effects of glutamine. Do not combine with milk or other protein foods.
