What does it do? Glutamine is the most abundant amino acid (protein building block) in the body and is involved in more metabolic processes than any other amino acid. Glutamine is converted to glucose when more glucose is required by the body as an energy source. It serves as a source of fuel for cells lining the intestines. Without it, these cells waste away. It is also used by white blood cells and is important for immune function. In animal research, glutamine has anti-inflammatory effects. Glutamine in combination with N-acetyl cysteine promotes the synthesis of glutathione, a naturally occurring antioxidant that is believed to be protective in people with HIV infection.1 Evidence indicates that intravenous glutamine supplementation increases the survival rate of critically ill people.2
Where is it found? Glutamine is found in many foods high in protein, such as fish, meat, beans, and dairy products.

Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit.
