Health Benefits of L-Glutamine
Glutamine is the most abundant single amino acid in both blood and muscle tissue; up to 60 percent of the amino acid content in skeletal muscle tissue is glutamine. Glutamine is an amino acid that helps build and maintain the muscles of the body. Supplemental glutamine is useful for dieters and bodybuilders.
Glutamine helps transport nitrogen to other parts of the body as well, the muscles in particular. By regulating levels of nitrogen and helping to replenish glycogen supplies in the muscles, glutamine helps prevent the muscle breakdown during particularly strenuous workouts. glutamine helps for preserving and building muscle mass.
Glutamine is also an important source of energy for the nervous system. If the brain is not receiving enough glucose, its compensates by increasing glutamine metabolism for energy. Glutamine users often report more energy, less fatigue and better mood.
Glutamine promotes a healthy digestive tract by helping to balance acid/alkaline levels in the body. Glutamine from food can be directly absorbed into the cells of the small intestine, and thus may be helpful for people with digestive troubles absorbing nutrients. It also helps remove toxic ammonia from the liver and helps maintain a healthy central nervous system.
Glutamine easily passes through the blood-brain barrier, a protective barrier formed by the red blood cells and the glia of the brain that protects the brain from any toxins, bacteria, and viruses that are circulating through the bloodstream.
Inside the brain glutamine may be converted into glutamic acid, another amino acid that helps sustain proper brain function; it also increases levels of gamma-aminobutyric acid (GABA), an amino acid that acts as a neurotransmitter in the body.
Glutamine is found in many foods, but it is easily destroyed by cooking. If eaten raw, spinach and parsley are good sources. Anyone with liver or kidney problems, Reye’s syndrome, or any type of disorder that can result in an accumulation of ammonia in the blood should not take glutamine, as it may aggravate these conditions.
