If Huge Gains Are What You're After, Glutamine is Essential. Recent research has confirmed that glutamine is essential for protein synthesis, complete recovery and immune function. Under intense training muscle protein losses may be prevented by taking supplemental glutamine. Additionally, studies have found that consuming supplemental glutamine stimulates the release of growth hormone, volumizes your muscle cells and helps control toxic ammonia. What's more, glutamine works in the gut helping to increase the absorption of other nutrients, such as creatine, making them work even better. CHAMPION NUTRITION's POWER GLUTAMINE contains only HPLC 100% pure L-Glutamine, the exact same kind as used in the clinical studies. It is virtually tasteless and mixes quickly and easily in to protein drinks or other beverages.
