Another thing, many of these IV studies with glutamine that show increases in LBM aren't looking at fractional increases in muscle mass. Meaning they don't look exclusively at muscle mass, they just lump all the body muscle into one category. Well guess what, in AIDS, cancer, & burn victims they all have massive tissue loss from the GI tract, well glutamine is the main fuel for the GI tract cells. So all that muscle that they show glutamine spares, is mostly just GI tract muscle anyway!
and other
training can reduce glutamine levels... but the fact remains that ORAL GLUTAMINE ingestion is essentially useless as around 80%-90% of it is lost to the gut. It is a non essential amino acid ((NEAA) meaning the body can make it, thus when NEAA's are ingested, the gut strips them to their carbon skelaton and synthesizes the NEAA's from these carbon structures on an AS NEEDED basis. If this were not the case we would all have drastic deficiencies in certain kinds of NEAA's and large surpluses of others.
layne of course is working towards his phd in amino acid metabolism, he's also a natural bodybuilder
