What it is

Niacin, also known as Vitamin B3, is a water-soluble vitamin essential for human health. It occurs naturally in foods like meat, fish, eggs, and grains. It can also be synthesized for use as a food additive.

Why it's used

Niacin is added to foods as a nutrient to help fortify them, increasing their nutritional value. It is commonly found in enriched grain products like bread and cereals, as well as in beverages.

Health notes

Niacin is recognized as safe and effective by the FDA when used as a nutrient. The U.S. National Academies have established an upper intake level for niacin. International bodies like JECFA and EFSA have also evaluated niacin. At typical dietary intake levels, niacin is generally considered safe. High doses, often from supplements, can cause side effects like skin flushing.

Allergen info

Niacin itself is not one of the major allergens. It is not derived from any of the major allergens and does not contain gluten.
