Conditionally Essential Amino Acid Glutamine, the most abundant amino acid in the body, is considered conditionally essential, meaning that under certain conditions (such as exercise-induced stress) glutamine becomes essential for repair and recovery from workouts.

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!

For the serious athlete, supplementing with L-Glutamine may:

• Aid in muscle tissue repair
• Enhance immune system function
• Volumize muscle cells
