EAS' L-Glutamine is a potent anabolic (muscle building) and anti-catabolic (prevents muscle breakdown) amino acid. Glutamine is the most abundant amino acid (protein building block) in the body. Glutamine is a nonessential amino acid under normal conditions. However, glutamine may become conditionally essential if demand for it exceeds the body's ability to produce it. This can happen during periods of stress, such as intense workouts.

Glutamine helps the immune system function optimally, enhances protein synthesis in body tissues, promotes muscle growth and helps the body to effectively recuperate from the physical stress of exercise. Studies suggest that following competition and intense exercise activity, glutamine levels may be reduced by as much as 50% in muscles. This can cause catabolism or muscle breakdown. Athletes and bodybuilders can benefit from glutamine supplementation to prevent muscle tissue breakdown and promote muscle building.

Independent studies suggest that glutamine can help increase muscle cell volume to stimulate protein synthesis in the cell. In one study, researchers found that after participants were administered 2 grams of glutamine, growth hormone levels increased 400 percent. Human growth hormone (HGH) is known for its powerful muscle building (anabolic) and fat preventing (lipotropic) effects.
