Absorption/Dlstrlbutlon - The average dietary intake of iron is 12 to 20 mg/day for males and 8 to 15 mg/day for females however, only about 10% of this iron is absorbed (1 to 2 mg/day) in individuals with adequate iron stores. Absorption is enhanced (20% to 30%) when storage iron is depleted or when erythropoiesis occurs at an increased rate. Iron is primarily absorbed from the duodenum and jejunum. The ferrous salt form is absorbed 3 times more readily than the ferric form. The common ferrous salts (ie, sulfate, gluconate, fumarate) are absorbed almost on a milligram-for-milligram basis but differ in the content of elemental iron. Sustained-release... 

Orally administered ferrous salts are the preferred treatment for iron deficiency. Ferrous salts are absorbed about three times as well as ferric salts and the bioavailability of the sulfate, fumarate, succinate, gluconate, and other ferrous salts is approximately the same. Ferrous sulfate, being the least expensive, is then the treatment of choice. Ferrous fumarate is available as a syrup and may be useful in small children for the treatment and prophylaxis of iron deficiency. 

Iron deficiency anemia occurs mainly in infants, children, and fertile women. For this reason, a variety of foods, including infant formula and infant cereals, is fortified with iron. Ferrous sulfate is a form of iron that is most readily absorbed by the gut, but when added to dry cereals it can promote their spoilage and rancidity. For this reason, dry cereals are fortified with elemental iron particles, ferric pyrophosphate, or ferrous fumarate (Davidsson et ah, 1997). Ascorbic add may also be added to the cereal to enhance iron absorption. To view some of the numbers, infant cereals may contain 75 mg iron/kg cereal (1.3 mmol iron/kg), 1 mmol phytic acid/kg, and 2.6 mmol ascorbic acid/kg (Davidsson et cd., 1997). Although phytic acid impairs iron absorption, the added ascorbate serves to prevent this effect. An alternate method for preventing phytate from impairing iron absorption is to treat the food with the enzyme phytase. A parent interested in enhancing a child s iron absorption can easily feed a child some orange juice, but it would not be practical to pretreat the child s cereal with phytase. A typical availability of ferrous sulfate in infants is about 3-5% (with no ascorbate), and 6-10% (with ascorbate). Ascorbate is effective when present in a twofold molar excess over the iron. 

One of the best iron supplements is Chromagen, which has ferrous fumarate, vitamin C, and desiccated stomach substance, a stomach protomorphogen that is claimed to improve assimilation of vitamin C. Considering the various iron supplements by themselves, desiccated liver is the best, in my opinion. After desiccated liver, 1 would recommend ferrous fiimarate, then ferrous sulfate, and, lastly, ferrous gluconate. Avoid any supplements whose chemical names begin with ferric. This is a form of iron with a higher electric charge than the ferrous minerals, and it has to be reduced to the ferrous state before it can be used. 

Supplements. Supplemental iron is available in two forms ferrous and ferric. Ferrous iron salts (ferrous fumarate, ferrous sulfate, and ferrous gluconate) are the best absorbed forms of iron supplements. Elemental iron is the amonnt of iron in a snpplement that is available for absorption. Figure 8.19 lists the percent elemental iron in these snpplements.
