Overview

Niacinamide, also called nicotinamide, is a form of vitamin B3. It's found in many foods including meat, fish, milk, eggs, green vegetables, and cereals.

Niacinamide is required for the function of fats and sugars in the body and to maintain healthy cells. Niacin is converted to niacinamide when it is taken in amounts greater than what is needed by the body. Unlike niacin, niacinamide doesn't help treat high cholesterol.

People use niacinamide to prevent vitamin B3 deficiency and related conditions such as pellagra. It is also used for acne, diabetes, cancer, osteoarthritis, aging skin, skin discoloration, and many other conditions, but there is no good scientific evidence to support most of these uses.

Do not confuse niacinamide with niacin, NADH, nicotinamide riboside, inositol nicotinate, or L-tryptophan. These are not the same.
