Most protein powders are fortified with L-glutamine. Why do you supplement with peptide bonded glutamine instead of L-glutamine like the rest?
Glutamine is included in these types of formulations because it is well known that supplementing with glutamine can result in increased lean tissue growth. Recent studies have suggested that glutamine supplementation is effective because it provides an immediate boost in growth hormone and free testosterone levels. These same recent studies have also suggested that food, particularly proteins or other amino acids, may decrease glutamine’s anabolic effect. L-glutamine is a free amino acid and, as such, can only be absorbed into the blood via a competitive absorption mechanism. It is this competitive absorption mechanism that may be responsible for the decreased anabolic effect of glutamine when the free amino acid is consumed in the presence of food, protein, or other amino acids. On the other hand, there are numerous studies that have concluded that peptide bound amino acids are absorbed far more efficiently into the body than free amino acids. Some studies claim that peptide bound ami
