The same can occur with elements in food, such as calcium, which impacts both heme and non-heme iron absorption. Absorption of iron is better at a low pH (i.e. an acidic environment), and absorption is decreased if there is a simultaneous intake of antacids. Many other substances decrease the rate of non-heme iron absorption. One example is tannins from foods such as tea and phytic acid. Because iron from plant sources is less easily absorbed than the heme-bound iron of animal sources, vegetarians and vegans should have a somewhat higher total daily iron intake than those who eat meat, fish or poultry.Taken after a meal, there are fewer side effects but there is also less absorption because of interaction and pH alteration. Generally, an interval of 2–3 hours between the iron intake and that of other drugs seems advisable, but is less convenient for patients and can impact on compliance. History
The first pills were commonly known as Blauds pills, which were named after P. Blaud of Beaucaire, the French physician who introduced and started the use of these medications as a treatment for patients with anemia. Administration
By mouth
Iron can be supplemented by mouth using various forms, such as iron(II) sulfate. This is the most common and well studied soluble iron salt sold under brand names such as Feratab, Fer-Iron, and Slow-FE. It is in complex with gluconate, dextran, carbonyl iron, and other salts. Ascorbic acid, vitamin C, increases the absorption of non-heme sources of iron.Heme iron polypeptide (HIP) (e.g.
