What Is L-Glutamine?
L-glutamine is an amino acid made by the body. It also can be made in a lab for use as a treatment for sickle cell disease. (The brand name is Endari®.) L-glutamine slows the damage that can happen from blockages caused by sickle cells. People with sickle cell disease who take L-glutamine may have fewer pain crises and hospital visits.
What Happens in Sickle Cell Disease?
Healthy red blood cells are soft, flexible, and round. Sickle cell disease makes red blood cells become sticky, hard, and C-shaped. The sickle cells get stuck and block the blood flowing inside small blood vessels. This can be painful and lead to other problems that need to be treated in a hospital.
Sickle cells also break down more quickly than healthy red blood cells. Not having enough red blood cells can lead to anemia. People with anemia feel tired and have less energy.
How Does L-Glutamine Help People With Sickle Cell Disease?
