Pure L-Glutamine is a conditionally essential amino acid. Glutamine is the most abundant amino acid in both the plasma (20%) and intracellular muscle tissue pools (60%). Glutamine plays many roles in our body that may directly or indirectly affect immune function, cellular recovery, protein synthesis, and muscle growth. It is the preferred gut fuel, as well as, the fuel source for rapidly dividing cells, such as enterocytes, coloncytes, fibroblasts, macrophages, lymphocytes and neoplastic cells. It is aprecursor to metabolic biosynthesis pathways such as gluconeogenesis. And due to its two-amine groups, glutamine is involved in nitrogen shuttling between cells.

The benefit of L-Glutamine  is two-fold. First, the exercising muscle causes a greater demand for L-Glutamine and the anabolic muscle building support this amino acid offers. Secondly, gyms and fitness centres are notorious germ incubators. Sweat and other bodily fluids are passed by hand contact from one user to another. Combine this germ exposure with hard training which can strain the immune system and you have an excellent recipe for illness. Utilizing L-glutamine supplementation can help fortify the glutamine reserves and potentially present muscle degradation and susceptibility to colds and flu.
