Description:

Ferritin is a protein that stores iron inside the body's cells. The body needs iron to produce healthy red blood cells. Red blood cells carry oxygen from the lungs to the rest of the body. Iron is also important for healthy muscles, bone marrow, and organs, including brain development in children. Too little or too much iron in the body can cause serious health problems.
