Iron & Ferritin

Iron is a mineral needed by hemoglobin, the protein in red blood cells that carries oxygen. Iron is also needed for energy and healthy muscle and organ function.

Ferritin is a protein in the body that binds to iron, so it is a measure of the body’s iron stores.

Low iron and ferritin can cause anemia. People with low iron or ferritin, or both, may need to take iron supplements. In severe cases, iron transfusions may be necessary.
