L-Glutamine is involved in many metabolic processes and regulates acid-base balance in the kidney. It is an important amino acid for the incorporation of ammonium ions into biomolecules. It is a vital component of culture media that serves as a major energy source for cells in culture. As a component in oral supplementation, it is useful for patients who have advanced stages of cancer to reverse cachexia (i.e. muscle wasting). It is also used for attention deficit-hyperactivity disorder (ADHD), a urinary condition called cystinuria, sickle cell anemia and for alcohol withdrawal support. It finds applications in patients with HIV (AIDS) to prevent weight loss.


Moisture and light sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with moisture and strong oxidizing agents.
