Ferrous Sulfate Thiamin Mononitrate

Ferrous sulfate is an iron salt that is often added to foods to increase their iron content. It is a synthetic compound, typically produced by reacting iron with sulfuric acid. Thiamin mononitrate is a synthetic form of vitamin B1 (thiamin), a nutrient essential for energy metabolism.

These ingredients are added to foods as nutrients, specifically to fortify them with iron and vitamin B1. They are commonly found in enriched grain products like pasta and bread, as well as in some frozen meals and deli salads, to help consumers meet their daily nutrient needs.

Ferrous sulfate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. Thiamin mononitrate is also approved by the FDA as a food additive for nutritional fortification. Both are essential nutrients. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated thiamin and set an acceptable daily intake. Excessive iron intake can cause gastrointestinal upset, but this is unlikely from typical food fortification levels. Evidence does not suggest significant health concerns at typical intake levels.
