Glutamine is the most abundant of these amino acids in the blood and in the free amino acid pool of skeletal muscle. In fact it makes up approximately 50-60% of the free amino acids in muscle (Roth, 1990). It is stored mainly in the muscles, but can also be found in the liver, lungs, brain, and plasma of the blood. It is used as fuel by tissues such as the small intestine, immune system, and hair follicles. Although Glutamine is classified as a nonessential amino acid because the body can synthesize it from other amino acids, most consider it to be a "conditionally essential" amino acid because of its high demand in the body at certain times. A pure L-glutamine supplement is dissolvable in a white powder form and has no taste. Studies have shown that overtrained athletes have been found to exhibit lower plasma glutamine concentrations than non-overtrained athletes (Castell and Newsholme 1997, Keast, Arstein, Harper, Fry, and Morton 1995). What this tells us is that because of the high demands for glutamine from the lymphocytes and macrophages during intense training and overtraining syndrome, immune system function may be compromised and contribute to the incidence of infectious disease or slower wound healing. Viral infections such as the everyday cold and flu to HIV all dramatically lower glutamine levels. Having a glutamine deficiency will lower the levels of our protective T cells and reduce the ability of macrophages to kill viruses and bacteria (Hack, Weiss, Friedmann, Suttner, Schykowski, Erge, Benner, Bartsch, and Drodge 1997). But, not all studies show an effect of glutamine supplementation after intense exercise. Note Glutamine and Creatine should be taken 90 minutes apart |
