Now Foods Supplements, L-Glutamine 500 mg, Nitrogen Transporter, Amino Acid, 120 Veg Capsules, White

Glutamine is considered to be a conditionally essential amino acid, which means that under certain circumstances, the body may require more glutamine than it can produce. In the body, glutamine functions as a major nitrogen transporter and is critical for the maintenance of healthy nitrogen balance.* Glutamine also acts as the primary fuel for the rapidly growing cells of the immune system and GI tract.*
