When tests are run on a protein supplement to determine how much of each amino acid is present, glutamine can end up being converted into glutamic acid and ammonia. The result is that some glutamine shows up as glutamic acid on the label. If the amino acid profile shown on the label of your protein supplement indicates that for example, 9 grams of glutamic acid is present, only a few grams of that may actually reflect glutamine that was converted into glutamic acid during testing. Remember also that the protein lists the amino acid profile for each amino acid in the protein. These amino acids are bonded together (peptide bonded) to make up that protein. They are not free form amino acids. In some of the initial alpha and beta testing in-house NITRIX® testing, subjects found that adding glutamine to NITRIX® "cancelled out" its effects. Why this may occur has been discussed in several published scientific studies, but at this stage is not 100% completely understood within the scientific community. One theory is that glutamine may reduce the availability of arginine for nitric oxide (NO) synthesizing enzymes. Thus, when you take high dosages of glutamine, less arginine ends up getting converted into NO. For this reason, we recommend limiting your intake of free form L-glutamine to 10 grams or less daily when taking NITRIX®.
