Oral iron absorption occurs in the duodenum and requires increased gastric acidity to allow iron to remain in the more soluble, ferrous form. Many patients with iron deficiency anemia who require oral iron repletion are on proton pump inhibitors (PPIs) for management of various conditions that require acid suppression for treatment.

Conversely, iron absorption is inhibited by plant phytates and tannins. These compounds also chelate iron, but prevent its uptake by the absorption machinery (see below). Phytates are prominent in wheat and some other cereals, while tannins are prevalent in (non-herbal) teas. Enhancers of iron absorption: ascorbic acid and other organic acids. Ascorbic acid (AA), with its reducing and chelating properties, is the most efficient enhancer of non-heme iron absorption when its stability in the food vehicle is ensured. 2019-07-31 2010-03-03 Iron deficiency is a major world health problem, that is, to a great extent, caused by poor iron absorption from the diet.

While the exact absorption of heme iron is unknown (estimated to be around 15-35%), we know that heme iron is more readily absorbed by the body than nonheme iron (about 3-20%).
