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 is also stored as a pigment called hemosiderin, which is an ill-defined deposit of protein and iron, created by macrophages where excess iron is present, either locally or systemically, e.g., among people with iron overload due to frequent blood cell destruction and the necessary transfusions their condition calls for. If systemic iron ...
About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.
From the outset, correcting an iron deficiency may seem small, but it can make a world of a difference in helping you feel empowered and in control of your health. Restoring iron to your body can ...
[55] [63] Iron can be found in three forms in the brain – magnetite, hemoglobin (blood) and ferritin (protein), and areas of the brain related to motor function generally contain more iron. [63] [64] Magnetite can be found in the hippocampus. The hippocampus is associated with information processing, specifically learning and memory. [63]
Iron is needed to develop the central nervous system (CNS), endocrine system, autoimmune system, and brain. Iron is involved with the development and functioning of different neurotransmitter systems and large iron quantities are required for the myelination of white brain matter.
A distinct family of cytochromes is the cytochrome P450 family, so named for the characteristic Soret peak formed by absorbance of light at wavelengths near 450 nm when the heme iron is reduced (with sodium dithionite) and complexed to carbon monoxide. These enzymes are primarily involved in steroidogenesis and detoxification. [14] [9]
