Condition
Sickle Cell Disease
Sickle cell disease is an inherited blood disorder in which red blood cells turn rigid and sickle-shaped, blocking blood flow and causing pain crises and organ damage. Evidence is moderate for folic acid, zinc and vitamin D, and studies of the antioxidant alpha-lipoic acid found oxidative stress markers went down. That finding is limited, though, drawn from four small studies with about 60 people.
