Vitamins And Minerals: Reduced Iron

Reduced iron is a form of iron used as a dietary supplement and food fortifier. It is made by reducing iron salts, often with hydrogen gas, to produce fine iron powder. This powder is then often treated to make it more bioavailable.

Reduced iron is added to foods to increase their iron content, helping to prevent iron deficiency. It is commonly found in breakfast cereals, enriched flour, and infant formulas. Its neutral taste and color make it suitable for a wide range of products.

The FDA considers reduced iron to be GRAS (Generally Recognized As Safe) for use as a nutrient supplement in food. Iron is an essential mineral for human health, playing a key role in oxygen transport. While iron deficiency is a public health concern, excessive iron intake can be harmful. JECFA has evaluated iron and set an acceptable daily intake. The US National Academies have established upper intake levels for iron. Evidence on the bioavailability of reduced iron compared to other forms is mixed.
