Iron Absorption

Iron absorption is affected by the form in which iron is presented to the digestive tract, and inorganic iron ions change oxidation state during the absorption process.

There are two major forms of dietary iron.

Some iron-rich foods are poor sources of the mineral because other compounds render it nonabsorbable.

Iron ions undergo two important changes of oxidation state during digestion and absorption.

The first change occurs in the stomach.

The second change occurs in the duodenum.
