Thimine Mononitrate

Thiamine mononitrate is a synthetic form of thiamine, also known as vitamin B1. It is a white crystalline powder produced through chemical synthesis. Thiamine is essential for carbohydrate metabolism and nerve function.

Manufacturers add thiamine mononitrate to foods as a nutrient supplement, primarily to fortify grain products like cereals, bread, and pasta. It is also used in infant formula and dietary supplements to help consumers meet their daily thiamine requirements.

Thiamine mononitrate is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The National Academies have set an upper intake level for thiamine. JECFA has evaluated thiamine and its salts, establishing acceptable daily intakes. Consuming thiamine mononitrate at typical levels found in fortified foods is not associated with adverse health effects.
