Vitamin B3 (Niacin & Niacinamide)

Merchandising recommendation: narrow this page to direct niacin and niacinamide products or consolidate it into B Vitamins until a meaningful assortment exists.

Only NOW Foods Niacinamide is clearly a direct vitamin B3 product from the current titles. Four other active records are NAD, NADH, or NAD-support formulas and should move to the NAD+ or cellular-energy taxonomy unless their labels contain a meaningful, clearly disclosed B3 amount.

Distinguish nicotinic acid, niacinamide, and other forms; do not equate NAD, NADH, or nicotinamide riboside products with a niacin supplement. High-dose niacin and cholesterol-related use require professional guidance because flushing, liver effects, glucose changes, medication interactions, and monitoring may be relevant.
