How much nonheme iron is absorbed?
Only 2–20% of nonheme iron is absorbed by the body, and absorption of nonheme iron is affected by a number of factors. It is also likely that dietary iron is taken into the intestinal cells as ferritin, the iron storage molecule of animal and plant cells.

Does vitamin D help absorb iron?
