Maximum Nutrition's Glutamine AKG 1500 provides a pharmaceutical grade concentration of 100% pure L-Glutamine. L-Glutamine is the most abundant free amino acid in skeletal muscle. During times of extreme stress on the body, L-Glutamine is rapidly stripped from muscle tissue. The key to success for any athlete, from novice to world class, is not necessarily the training program itself, but the ability to recover post-training. Supplementation with L-Glutamine may greatly enhance the body's ability to recover as well as support healthy immune function. With Maximum Nutrition's Glutamine AKG 1500?s pharmaceutical delivery and stability system, each 2 capsule dose allows the athlete to take less product and experience even greater results. L-Glutamine-Alpha-Ketoglutarate Used for repair, recovery and muscle soreness. AKG is used to deliver glutamine into blood stream.
