The role and current status of heme iron preparations in people with iron depletion

Iron deficiency is a common but underestimated condition in the population. Its correlate is far from only sideropenic anemia, but is due to the variety of involvement of this element in a number of bio chemical reactions; several other possible clinical manifestations can be expected. Appropriately selected oral supplementation is often necessary. Here, we should carefully consider the possible ratio of expected benefits and potential risks of side effects, or interaction with dietary components or concomitant medications. The available preparations are not equivalent; they differ not only in atomically different amounts of iron but also, above all, in the form that determines the way in which the iron will be absorbed. This ultimately defines the rate of adjustment for depletion and the tolerability of a particular product.
