Glutamine is an amino acid widely used to maintain good
brain functioning. Glutamine is 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 in animal proteins.
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.
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. Thus is popular in
Athletic people need more glutamine than more sedentary people. Glutamine is the most
plentiful free amino acid in the body's muscle tissue. L-Glutamine plays a very important
role in protein metabolism, cell volumizing, and anti-catabolism, which means that it may
help prevent your muscle's breakdown.
Under periods of stress such as very intense workouts, glutamine becomes critical because
your body may not be able to make enough of it. But studies show that glutamine
supplementation is an effective way to replace these declining levels and thus help
maintain peak athletic performance.
Glutamine is the primary source of energy for cells of the GI tract and immune system,
thereby providing health benefits to both.
