Glutamine243Glutamine is a non-essential amino acid that generates energy and helps increase strength, quicker recovery, and exercise endurance. Blood ammonia concentration increases during endurance exercise and has been proposed as a cause for both peripheral and central fatigue. In trials, glutamine supplementation reduced the accumulation of blood ammonia during prolonged, strenuous exercise in high-level athletes. As an immune booster, glutamine supplementation may prevent the negative effects of strenuous exercise on immune function. Moreover, glutamine supplementation has a protective effect in the DNA fragmentation, mitochondrial membrane depolarization and apoptosis, and in regulation of the inflammatory process and immune suppression, which are induced by a single session of exercise. Glutamine also plays an important role in maintaining functional integrity of the gut. As a gut-trophic factor, glutamine improves intestinal function, allowing better absorption of nutrients. Glutamine is also widely used to maintain good brain functioning. As a derivative of glutamic acid, which is synthesized from the amino acids arginine, ornithine and proline, glutamine improves mental alertness, clarity of thinking and mood. It is found abundantly in animal proteins and needed in high concentrations in serum and cerebro-spinal fluid. When glutamic acid combines with ammonia, a waste product of metabolic activity, is converted into glutamine. Glutamic acid is also a precursor of GABA, an important neurotransmitter in the central nervous system. Glutamic acid helps transport potassium into the spinal fluid and is itself an excitatory neurotransmitter. Glutamic acid has been used to treat mental retardation, epilepsy, Parkinson’s disease, muscular dystrophy and alcoholism. Because glutamic acid cannot cross the blood brain barrier, where most of the metabolism takes place, glutamine, which can cross this barrier, works better in supplement form. Glutamine can also be used by cells like glucose for metabolic energy. It helps to raise blood sugar and is therefore valuable in the treatment of hypoglycemia. Research has also shown that supplementation of glutamine reduces the craving for alcohol and is now commonly used in alcoholism clinics. It also seems to reduce the craving for sugar and carbohydrates. Other noted areas of usefulness are treatment of depression, peptic ulcers, schizophrenia and senility, and behavioral problems and autism in children.* Directions: Take one capsule once or twice daily on an empty stomach, or as recommended by a healthcare practitioner.
