    Iron Health Professional Fact Sheet

    Unlike other inhibitors of iron absorption, calcium might reduce the bioavailability of both nonheme and heme iron. However, the effects of enhancers and inhibitors of iron absorption are attenuated by a typical mixed western diet, so they have little effect on most peoples iron status. Several food sources of iron are listed in Table 2.
