The absorption of dietary iron is a variable and dynamic process. The amount of iron absorbed compared to the amount ingested is typically low, but may range from 5% to as much as 35% depending on circumstances and type of iron. The efficiency with which iron is absorbed varies depending on the source.
While this form of iron is also valuable, it is generally less easily absorbed by the body than heme iron. However, nonheme iron absorption can be enhanced by consuming it with vitamin C-rich ...

Ferrous iron is then absorbed in the small intestine where it is oxidized into its ferric iron (Fe 3+) form before being released into the bloodstream. [4] Free iron in the blood is toxic to the body as it disrupts normal cell function, damaging organs such as the liver, stomach, and cardiovascular system. [4]
Red meat is an obvious and effective way to boost iron levels, as it’s easily absorbed. A 4-ounce serving of ground beef , for example, packs 2.19 mg of iron, over 12% of the daily value.
The same can occur with elements in food, such as calcium, which impacts both heme and non-heme iron absorption. [39] Absorption of iron is better at a low pH (i.e. an acidic environment), and absorption is decreased if there is a simultaneous intake of antacids. Many other substances decrease the rate of non-heme iron absorption.
Iron provided by dietary supplements is often found as iron(II) fumarate, although iron(II) sulfate is cheaper and is absorbed equally well. [145] Elemental iron, or reduced iron, despite being absorbed at only one-third to two-thirds the efficiency (relative to iron sulfate), [165] is often added to foods such as breakfast cereals or enriched ...
Iron from food is absorbed into the bloodstream in the small intestine, primarily in the duodenum. [38] Iron malabsorption is a less common cause of iron-deficiency anemia, but many gastrointestinal disorders can reduce the body's ability to absorb iron. [39] There are different mechanisms that may be present.
