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. Glutamine accounts for about 60% of the body’s total intramuscular free amino-acid pool and 20% of the total circulating amino acids. Unlike almost all other aminos, glutamine contains two nitrogen atoms. Because of this additional nitrogen atom, glutamine is called a nitrogen “shuttle.” Glutamine transports nitrogen where the body needs it most. |
