What it is

Vitamin B1, also known as 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. Manufacturers can also produce it synthetically for use as a food additive.

Why it's used

Manufacturers add thiamine to foods, particularly refined grains, to restore nutrients lost during processing. It functions as a nutrient, helping to fortify products like breads, cereals, and pasta. It is also used in some dietary supplements.

Health notes

Thiamine is recognized as safe and effective by the FDA when used as a nutrient supplement in food. The U.S. National Academies have established a tolerable upper intake level for thiamine. International bodies like JECFA and EFSA have also evaluated thiamine. Deficiency can lead to serious health issues, but at typical intake levels from fortified foods and a balanced diet, it is generally considered safe and beneficial.

Allergen info

Thiamine is not derived from any of the 9 FDA major allergens. It does not contain gluten.
