What it is

Vitamin B1, also called thiamine, is a water-soluble vitamin essential for carbohydrate metabolism and nerve function. It is found naturally in foods like whole grains, pork, and legumes. In food production, it is often added as a synthetic nutrient.

Why it's used

Manufacturers add vitamin B1 to fortify foods, helping consumers meet their daily nutritional needs. It is commonly found in breakfast cereals, bread, pasta, and infant formulas.

Health notes

Vitamin B1 is recognized as safe and effective for food fortification by the FDA. The U.S. National Academies have established an upper intake level for thiamine. JECFA and EFSA have evaluated thiamine and established acceptable daily intakes. Deficiency can lead to serious health issues, but it is rare in developed countries due to fortification and dietary intake.

Allergen info

Vitamin B1 is not derived from any of the nine FDA major allergens. It does not contain gluten.
