It's a similar story with iron. If you're deficient, your body starts grabbing all the iron it can from your diet.
And this begs the question the why? Why is your body trying to conserve it? As I asked before, why does vitamin A get to stay in the VIP lounge of the liver, while almost every other dangerous element accumulates elsewhere in the body? The liver's job is not to store anything, it's job is to metabolize.
Well, being deficient isn't the only time the body tries to load up on iron. In some diseases like sickle cell and thalessemia, when red blood cells can't be made right, the body absorbs extra iron to try and make more red blood cells, even when iron stores are already high. Blood transfusions can often compound this problem. There are also the genetic loading disorders, which can cause the body to continue to absorb iron, even when sufficient. And supplemental forms can also overload the normal feedback mechanisms, either through design (such as the Ferric EDTA complex), or by sheer amounts added.
