Vitamin B1 Thiamine Mononitrate

Thiamine mononitrate is a synthetic form of vitamin B1, an essential nutrient. It is made through a chemical process involving thiamine and nitric acid. It is often used to fortify foods because it is more stable than other forms of thiamine.

Manufacturers add thiamine mononitrate to foods to increase their vitamin B1 content, helping to prevent deficiencies. It is commonly found in enriched grains like bread and cereal, as well as in some processed foods such as frozen pancakes and rice mixes.

Thiamine mononitrate is recognized as safe and effective by the FDA when used as a nutrient supplement. The U.S. National Academies have established upper intake levels for thiamine. JECFA and EFSA have evaluated thiamine and its compounds, establishing acceptable daily intakes. It is crucial for energy metabolism and nerve function. Typical intake from fortified foods is not associated with adverse effects.
