Glutamine the most abundant amino acid in the body It plays a crucial role in cell volumizing and has powerful anabolic and anti-catabolic effects, promoting protein synthesis while inhibiting protein breakdown. Loading with glutamine may even increase the secretion of growth hormone. Studies show that supplementing with as little as two grams of free-form L-glutamine may boost your growth hormone levels by as much as 400%. Glutamine Reduces Muscle Deterioration Glutamine is high in demand throughout the body and is used in the gut and immune system extensively to maintain optimal performance. Studies show that training over an extended period of time, rapidly depletes both muscle and blood glutamine levels.
What's worse, during periods of stress, glutamine is further depleted, and if not reversed, glutamine is pulled directly from the muscle. For strength athletes and bodybuilders, glutamine is extremely important. When supplemented, it may help body builders reduce the amount of muscle deterioration that occurs because other tissues that need glutamine will not rob the glutamine stored in the muscle cells. In catabolic states of injury and illness, glutamine becomes conditionally-essential(requiring intake from food or supplements). Glutamine has been studied extensively over the past 10–15 years and has been shown to be useful in treatment of serious illnesses, injury, trauma, burns, and treatment-related side-effects of cancer as well asin wound healing for postoperative patients
Glutamine is the primary source of energy for the various cells of the immune system. Strenuous exercise, viral and bacterial infections, and stress in general cause glutamine depletion that starves the immune cells. Up to 40 grams per day can be used to sustain the immune systems of AIDS or cancer patients undergoing bone marrow transplantation. Very ill patients suffer both a decrease in glutamine levels and muscle loss. The use of glutamine has been documented to aid the survival of severely ill surgical and burn patients. It also speeds up wound and burn healing and improves recovery in general.
