What it is

Thiamin mononitrate is a synthetic form of thiamin, also known as vitamin B1. Thiamin is essential for carbohydrate metabolism and nerve function. It is produced through chemical synthesis.

Why it's used

Manufacturers add thiamin mononitrate to fortify foods, meaning to add back nutrients lost during processing or to increase the nutritional value. It is commonly found in enriched grain products like bread, cereals, and pasta, as well as in some beverages and infant formulas.

Health notes

In the U.S., thiamin mononitrate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated thiamin and has established an acceptable daily intake. No significant health concerns are associated with typical dietary intake of thiamin from fortified foods.

Allergen info

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