“Calcium inhibits the absorption of nonheme iron (the type of iron found in supplements and plant-based sources) by competing for absorption in the intestines,” says Carla Hernandez, RDN, a ...
However, this effect is often not seen in practice and reduction of absorbed minerals can be attributed mainly to the phytic acids in fibrous food. [11] [12] Foods high in calcium eaten simultaneously with foods containing iron can decrease the absorption of iron via an unclear mechanism involving iron transport protein hDMT1, which calcium can ...
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.
Non-heme iron is more sensitive to both inhibitors and enhancers of iron absorption: Vitamin C is an iron absorption enhancer; the main inhibitors for most people are phytates (e.g. legumes and cereal grains), but other inhibitors include tannins (from tea and wine), calcium, and polyphenols. [1]
