A conditionally essential amino acid which only appears to benefit the body as supplementation when otherwise deficient (vegans, vegetarians with low dairy intake) or during prolonged endurance exercise. Anecdotally reported to reduce sugar cravings. Glutamine is one of the 20 naturally occurring amino acids in dietary protein, specifically, it is a conditionally essential amino acid (being elevated to essential during periods of disease and muscle wasting typical of physical trauma). It is sold as an isolated Amino Acid as well as is found in high levels in dietary meats and eggs. It is found in very high levels in both whey and casein protein. Glutamine is a very effective intestinal and immune system health compound, as these cells use glutamine as the preferred fuel source rather than glucose.
