The most active site of iron absorption is the duodenum, but the stomach, ileum, and colon may also participate to a small degree. In the stomach, the luminal mucin and acid pH facilitate inorganic iron absorption. Gastric mucin binds to inorganic iron in the lumen, and gastric acid maintains ferric iron in a soluble form.

The duodenum receives partly digested food from the stomach, called acid chyme, as well as digestives enzymes from the pancreas that break down proteins. of malabsorption of carbohydrates and fat; anemia may occur due to inadequate levels of iron, copper, or folic acid and vitamin B12; osteopenia or osteoporosis.
