Excess supplements: A person absorbs iron from foods and oral iron supplements because human bodies require iron. If he is low in iron, his body will improve its absorption of iron. If he has plenty of iron, his body won't absorb as much iron. But, he will not stop absorbing iron. That means he can get iron overload by taking too high a dose of iron supplements. Iron overload damages the liver and other organs.
