What is the typical daily dietary iron absorption percentage in healthy individuals?

The typical daily dietary iron absorption percentage in healthy individuals is between 5% to 15%. This range reflects the body's ability to absorb iron from various dietary sources, which can vary based on several factors, including the type of iron (heme versus non-heme), the presence of enhancers such as vitamin C, and inhibitors like phytates and calcium.

Heme iron, found primarily in animal products, tends to have a higher absorption rate than non-heme iron, which is found in plants. For most healthy individuals consuming a mixed diet that includes both heme and non-heme sources, daily iron absorption falls within this 5% to 15% range.

This understanding of iron absorption is crucial in clinical settings, especially in evaluating dietary intake and the risk of anemia, as well as in developing appropriate recommendations for individuals at risk of iron deficiency.
