Nlacin

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

Niacin is added to foods as a nutrient supplement, often to fortify grains like flour and cereals. It plays a role in energy metabolism and is important for the nervous system and skin health. It is commonly found in enriched bread, pasta, and breakfast cereals.

Niacin is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The World Health Organization (WHO) and the European Food Safety Authority (EFSA) have evaluated niacin and established acceptable daily intakes. At typical dietary levels, niacin is safe and beneficial. High supplemental doses, far exceeding typical food levels, can cause side effects like skin flushing, but these are not associated with niacin added to foods.
