Ferrous iron is then absorbed in the small intestine where it is oxidized into its ferric iron (Fe 3+) form before being released into the bloodstream. [4] Free iron in the blood is toxic to the body as it disrupts normal cell function, damaging organs such as the liver, stomach, and cardiovascular system. [4]
Many metals, particularly heavy metals are toxic, but some are essential, and some, such as bismuth, have a low toxicity. Metals in an oxidation state abnormal to the body may also become toxic: chromium(III) is an essential trace element, but chromium(VI) is a carcinogen. Only soluble metal-containing compounds are toxic.
Human iron metabolism is the set of chemical reactions that maintain human homeostasis of iron at the systemic and cellular level. Iron is both necessary to the body and potentially toxic. Controlling iron levels in the body is a critically important part of many aspects of human health and disease.

Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
Iron deficiency and iron-deficiency anemia are fairly common medical issues that can leave people feeling tired and even short of breath. But new research has found there’s one group that may be ...
