Heme iron charge
Webheme iron. Studies of food iron bioavailability appear to have conflicting results (see Table 2). These may be better understood by considering the behaviors of the different chemical forms of the non-heme iron used, such as ferric citrate or ferric chloride. Each form has a different chemistry in the stomach or in the gut.
