Iron Overload

Horses are unique in their ability to conserve iron. [Heme is recycled rather than excreted...iron deficiency is virtually non-existant...bioavailability of different sources of excessive iron not known...iron panel to dx anemia...spleen storage of RBCs]
As in humans, iron overload has been associated with insulin resistance and may co-exist with other metabolic conditions.
Iron overload in horses is a fairly recent concern and one which is mostly not recognized or often disregarded by feed and supplement manufacturers.
