Thiamine

Thiamine, also known as vitamin B1, is a water-soluble vitamin essential for carbohydrate metabolism and nerve function. It is found naturally in whole grains, meat, and legumes. It can also be produced synthetically for use as a food additive.

Thiamine is added to foods as a nutrient supplement, particularly in enriched grains like bread and cereals, to help prevent deficiencies. It is also used as a flavoring agent in some processed foods.

Thiamine is recognized as safe and effective by the FDA when used as a nutrient supplement. It is an essential nutrient, and deficiency can lead to serious health issues. International bodies like JECFA and EFSA have evaluated thiamine. Typical intakes from fortified foods are generally considered safe and beneficial for public health.
