What it is

Zinc oxide is a white powder that is naturally occurring but often produced industrially. Reduced iron is a form of iron powder made by reducing iron oxides. Both are used as nutritional supplements.

Why it's used

These ingredients are added to foods, primarily cereals, to fortify them with essential minerals, iron and zinc. This helps boost the nutritional content of the product.

Health notes

In the US, zinc oxide and reduced iron are permitted as nutrients in food. The FDA considers them safe when used as intended. JECFA has evaluated these substances and established acceptable daily intakes. Evidence does not suggest adverse health effects at typical intake levels from fortified foods.
