What it is

Ferrous sulfate is an iron salt that appears as a white to bluish-green crystalline powder. It is produced industrially by reacting iron with sulfuric acid. It is commonly used as a source of iron in foods and supplements.

Why it's used

Manufacturers add ferrous sulfate primarily to fortify foods with iron, which is an essential nutrient. It is often found in enriched breads, cereals, and pasta products to help prevent iron deficiency. It can also be used as a colorant in some applications.

Health notes

Ferrous sulfate is generally recognized as safe (GRAS) by the FDA for use as a nutrient supplement and food additive. Iron is essential for human health, and ferrous sulfate is a common source used in food fortification. JECFA (Joint FAO/WHO Expert Committee on Food Additives) has evaluated iron salts, including ferrous sulfate, and established acceptable daily intakes. While generally safe at recommended levels, high doses of iron can cause gastrointestinal upset.

Allergen info

Ferrous sulfate is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
