What Is Niacin?
Niacin (CAS No. 59-67-6) is a water-soluble B vitamin that naturally occurs in many foods and plays a critical role in the conversion of carbohydrates, fats, and proteins into energy (ATP). Chemically known as nicotinic acid, it can also be converted into niacinamide (nicotinamide), another bioavailable form with a different functional profile in skincare and medical applications.
Niacin is a coenzyme precursor for NAD and NADP, two essential molecules for more than 400 enzymatic reactions in the human body, including DNA repair, detoxification, and cell regeneration.
