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.
Iron is a mineral that is crucial for optimal health and well-being. Found naturally in many foods and dietary supplements, it is a key component of hemoglobin, the part of red blood cells ...
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 ...

In fact, over a third of U.S. females ages 12 to 21 are iron-deficient, with heavy periods, pregnancy and the postpartum period being major causes of iron deficiency anemia.
Roughly 5 grams of iron are present in the human body and is the most abundant trace metal. [1] It is absorbed in the intestine as heme or non-heme iron depending on the food source. Heme iron is derived from the digestion of hemoproteins in meat. [4] Non-heme iron is mainly derived from plants and exist as iron(II) or iron(III) ions. [4]
White beans. There’s a reason beans are a go-to for plant-based eaters. One half-cup of white beans offers nearly 3.5 mg of iron, the USDA says, along with 8.7 grams (g) of protein and 5.6 g of ...
