Iron homeostasis

Iron homeostasis is the body's way of maintaining the right balance of iron, an essential mineral for producing red blood cells and supporting energy production. The body absorbs iron from food in the intestines, uses what it needs, and stores excess in the liver. When the body needs more iron, it increases absorption; if it has enough, it reduces absorption to prevent overload. The hormone hepcidin plays a key role by regulating iron release from storage and absorption. Proper iron balance is vital; too little causes anemia, while too much can harm organs.
