Another name for niacin is vitamin B3.
Niacin, a water-soluble B vitamin, goes by several names, but vitamin B3 is the most common alternative. It's essential for various bodily functions. Niacin also encompasses the terms nicotinic acid, nicotinamide (or niacinamide), and related derivatives such as nicotinamide riboside. While these terms refer to specific forms, "niacin" generally serves as the overarching term.
