What it is

Thiamine mononitrate is a synthetic form of thiamine, also known as vitamin B1. Thiamine is an essential nutrient that plays a key role in energy metabolism. It is produced through chemical synthesis.

Why it's used

Thiamine mononitrate is added to foods as a nutrient supplement, primarily to fortify grain products like rice and cereals. This helps to replace thiamine lost during processing and ensures consumers receive adequate amounts of this essential vitamin.

Health notes

Thiamine mononitrate is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated thiamine mononitrate and established an acceptable daily intake. Typical intakes from fortified foods are well within safe levels and contribute to meeting daily thiamine requirements. No significant health controversies are associated with its use at typical levels.

Allergen info

Thiamine mononitrate is not derived from any of the nine FDA major allergens. It does not contain gluten.
