What it is

Vitamin B-1, also known as thiamine, is a water-soluble vitamin essential for carbohydrate metabolism and nerve function. It occurs naturally in whole grains, meat, and legumes. In food production, it can be synthesized.

Why it's used

Manufacturers add thiamine to foods, especially refined grains like bread and cereal, to restore nutrients lost during processing. It is often used as a nutrient supplement in fortified foods to help consumers meet their daily intake needs.

Health notes

Thiamine is a vital nutrient. The U.S. Food and Drug Administration (FDA) recognizes thiamine as safe and allows its addition to foods. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated thiamine and established guidelines for its use. Typical dietary intake is generally considered safe and beneficial for health.

Allergen info

Thiamine itself is not one of the FDA's nine major allergens, nor is it related to gluten. Not a major allergen.
