Iron storage refers to the way the body manages and holds onto iron, an essential mineral necessary for producing red blood cells and transporting oxygen. The body stores iron primarily in the liver, spleen, and bone marrow, using proteins like ferritin and hemosiderin to keep it in a safe, usable form. When the body needs iron, it can draw from these storage sites to maintain healthy levels. Proper iron storage is crucial because both excess and deficiency can lead to health issues, such as iron deficiency anemia or hemochromatosis, a condition caused by excessive iron accumulation.
