Glutamine is highly in demand throughout the body. It is used in the gut and immune system extensively to maintain optimal performance. 60% of free-form amino acids floating in skeletal muscles is L-glutamine. L-glutamine plays a very important role in protein metabolism, and it appears to be a very important nutrient for body builders. 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.

Research shows that after intensely working out, glutamine levels in the body are reduced by as much as 50%. Since the body relies on glutamine as cellular fuel for the immune system, scientific studies have shown that glutamine supplementation can minimize the breakdown of muscle tissue and improve protein metabolism. Its effects on replenishing the body after stress or trauma have been shown in Europe where it is commonly given to patients in hospitals. Glutamine's cell-volumizing effects have also been shown in several studies. No conclusive studies have been done to evaluate the effects of L-glutamine supplementation on weight-training adults; however, a recent study showed up to a 400% increase in growth-hormone levels when as little as 2 grams of free-form L-glutamine supplement was consumed!
