The reported inhibition of iron absorption by calcium is the same for nonheme and heme iron (2, 11). Because heme and nonheme iron are absorbed by differ- ent receptors on the mucosal surface, inhibition by calcium must be located within the mucosal cell at some transfer step common to the 2 kinds of iron.
What blocks the absorption of iron?
Calcium (like iron) is an essential mineral, which means the body gets this nutrient from diet. Calcium is found in foods such as milk, yogurt, cheese, sardines, canned salmon, tofu, broccoli, almonds, figs, turnip greens and rhubarb and is the only known substance to inhibit absorption of both non-heme and heme iron.
Does calcium help iron absorption?
Calcium-Rich Foods
Studies have shown that 165 mg of calcium from milk, cheese or a supplement reduced iron absorption by around 50–60% ( 4 , 17 ). This is worrisome, as increased calcium intake is commonly recommended for children and women, the same populations that are at risk of iron deficiency.
