title: Are iron supplements appropriate for iron replete pregnant women?
abstract: Iron replete pregnant women often are routinely advised to take a daily supplement of 30-40mg iron. An extensive review of controlled trials has failed to demonstrate that this practice improves clinical outcome of mother or newborn. However, this iron loading has long been assumed to be harmless. Recently, two hazardous complications of pregnancy, gestational diabetes and pre-eclampsia, have been recognized to be associated with iron loading. Accordingly, it may be appropriate to consider performing, at the patient's initial prenatal medical visit, a serum ferritin test to ascertain iron status. This simple procedure would enable evidence-based medical practice to replace mass medication with iron, a potentially toxic element.
