Glutamine plays key roles in protein metabolism, cell volumizing, and anti-catabolism.
Glutamine is the most abundant amino acid in the bloodstream and in muscles (over 61% of skeletal muscle is Glutamine). It participates in many metabolic processes and is also a major fuel source for intestinal, immune and brain cells. Glutamine regulates nitrogen transport to and from muscle tissue, establishing amino acid balance. Studies have shown that L-Glutamine has anti-catabolic properties (prevents or minimizes muscles breakdown) and also improves protein metabolism.
Although the body has the ability to make glutamine, extreme physical or mental stress, the kind you would experience after an injury, surgery, or heavy exercise can increase the demand for glutamine. So, increasing glutamine uptake through supplementation, could increase protein synthesis & speed wound healing and post-exercise recovery
