What it is

Thiamin mononitrate is a synthetic form of thiamin, also known as vitamin B1. It is produced through chemical synthesis and is commonly used to fortify foods. Thiamin is essential for converting carbohydrates into energy and for the proper functioning of the nervous system.

Why it's used

Manufacturers add thiamin mononitrate to foods as a nutrient supplement, primarily to fortify cereals, bread, and pasta. It helps restore thiamin levels lost during food processing. It is often found in baked goods, breakfast cereals, and enriched grain products.

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated thiamin and its derivatives, establishing acceptable daily intakes. At typical dietary intake levels, it is considered safe and essential for health.
