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, and whole grains. It can also be produced synthetically for use as a food additive.

Why it's used

Niacin is added to foods as a nutrient supplement, often to fortify grains and cereals. It plays a role in energy metabolism and is commonly found in products like bread, pasta, and breakfast cereals to help consumers meet their daily vitamin needs.

Health notes

Niacin is recognized as safe and effective by the FDA when used as a nutrient. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated niacin and established an acceptable daily intake. High doses of niacin can cause side effects like skin flushing, but these are generally not seen at typical dietary intake levels.

Allergen info

Niacin is not a major allergen and does not contain gluten.
