"Glutamine is one of the most versatile of all amino acids, and among the top aminos used by elite athletes. Among its many functions, glutamine detoxifies ammonia, regulates protein synthesis and protein degradation, functions as a nitrogen precursor and transfer, promotes cellular hydration, stimulates growth hormone production, maintains acid balance, boosts the immune system, is an energy precursor and increases glycogen production in the liver. In short, glutamine is both anabolic and anti-catabolic."
