What it is

Vitamin B1, also known as thiamine, is a water-soluble vitamin essential for carbohydrate metabolism and nerve function. It occurs naturally in many foods, including whole grains, meat, and legumes. In food production, it can be synthesized chemically.

Why it's used

Manufacturers add thiamine to foods, especially refined grains like bread and cereals, to restore nutrients lost during processing. It acts as a nutrient fortification, helping consumers meet their daily requirements. It is commonly found in baked goods, breakfast cereals, and pasta.

Health notes

Thiamine is recognized as safe and effective by the FDA when used as a nutrient supplement. The WHO and EFSA have evaluated thiamine and established guidance on its intake. At typical dietary levels, it plays a vital role in energy metabolism. Deficiencies can lead to serious health issues, but these are rare in developed countries with fortified foods.

Allergen info

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