Glutamine is an amino acid (a building block for proteins), found naturally in the body.
Glutamine is taken by mouth for sickle cell disease, to improve nutrition and help people recover from surgery, injuries, burns, bone marrow transplant, complications of HIV/AIDS, radiation, and cancer chemotherapy, and for many other uses. Glutamine is given intravenously (by IV) for improving recovery after surgery and other conditions.
Glutamine is commercially available as capsules or in packets as a powder form. There are two prescription glutamine products approved by the U.S. Food and Drug Administration (FDA): Endari (Emmaus Medical, Inc) and NutreStore (Emmaus Medical, Inc). Glutamine for commercial use is made by a fermentation process using bacteria that produce glutamine.
