Niacinamide (Nicotinamide, 3-pyridinecarboxamide; CAS 98-92-0) is the amide form of Vitamin B3 (niacin). It is a water-soluble white crystalline powder that occurs naturally in many foods (meat, fish, eggs, dairy, mushrooms, legumes, nuts, whole grains) and is synthesized industrially from beta-picoline or nicotinic acid. Niacinamide has TWO distinct major use categories: (1) Dietary/Functional Vitamin — used to prevent pellagra and as a vitamin B3 source in food fortification (cereals, flour, infant formulas) and dietary supplements. The FDA-recognized Recommended Daily Intake is 14-16 mg/day. (2) Cosmetic Skincare Active — Niacinamide is one of the most widely used cosmetic actives globally, prized for its multifunctional benefits: improves skin barrier function (boosts ceramide synthesis), reduces hyperpigmentation (inhibits melanosome transfer), regulates sebum production, calms inflammation and redness, minimizes the appearance of pores, and provides antioxidant defense. Typical use concentration in skincare: 2-10%. Appears in serums, moisturizers, toners, eye creams, sunscreens, and acne treatments. The FDA recognizes Niacinamide as GRAS under 21 CFR 184.1530 for food use; FDA-approved as a food additive and as a topical OTC ingredient. CosIng-listed under EU Cosmetic Products Regulation (EC) 1223/2009 with multiple functions (skin conditioning, antimicrobial, smoothing). CIR-assessed safe. EWG hazard: 1 (lowest).
