2. What Is Niacin (Vitamin B3)?
Niacin is an essential B-complex vitamin that functions as a biochemical precursor of nicotinamide adenine dinucleotide (NAD⁺) and NAD phosphate (NADP⁺), which are critical coenzymes involved in cellular energy metabolism and redox reactions.
In industrial applications, niacin is commonly supplied as nicotinic acid powder, distinguished from niacinamide (nicotinamide) by its chemical structure, solubility profile, and formulation behavior. Niacin is widely used as a nutritional fortification ingredient, functional cosmetic active, and pharmaceutical intermediate, subject to regional regulatory frameworks.
