Niacin B3

Niacin, also known as Vitamin B3, is an essential nutrient that plays a role in energy production and cell function. It is found naturally in foods like meat, fish, eggs, and grains. Industrially, it can be synthesized through chemical processes.

Niacin is often added to foods as a nutrient supplement, particularly in fortified cereals, bread, and pasta. Manufacturers add it to help consumers meet their daily vitamin B3 requirements. It is also used as a food additive for other purposes, such as improving texture and flavor in some products.

Niacin is recognized as safe and effective by the FDA when used as a nutrient supplement. The National Academies have established a Tolerable Upper Intake Level (UL) for supplemental niacin to prevent adverse effects like skin flushing. International bodies like JECFA and EFSA have also evaluated niacin, and it is considered safe when consumed within recommended dietary guidelines. Research has explored niacin's potential role in managing cholesterol levels, but it is not a substitute for medical treatment.
