Thiamine Mononitrate Folic Acid

Thiamine mononitrate is a synthetic form of vitamin B1 (thiamine), and folic acid is a synthetic form of vitamin B9 (folate). Both are produced through chemical processes. They are often combined to fortify foods with essential nutrients.

Manufacturers add thiamine mononitrate and folic acid to foods to increase their nutritional value, helping to prevent nutrient deficiencies. They are commonly found in enriched grain products like rice, flour, bread, and pasta, as well as in cereals and some prepared meals.

Both thiamine mononitrate and folic acid are recognized by the FDA as safe for use in food fortification. Thiamine is crucial for energy metabolism and proper nerve function, while folic acid is vital for cell growth and DNA formation, especially important during pregnancy to prevent birth defects. JECFA has evaluated both thiamine and folic acid and, as essential nutrients, did not set a specific acceptable daily intake (ADI). There are no significant controversies regarding their use as fortifying agents at typical intake levels.
