Overview

There are two forms of vitamin B3 - niacin and niacinamide. Niacinamide is found in many foods including yeast, meat, fish, milk, eggs, green vegetables, beans, and cereal grains. Niacinamide is also found in many vitamin B complex supplements with other B vitamins. Niacinamide can also be formed in the body from dietary niacin.

Do not confuse niacinamide with niacin, NADH, nicotinamide riboside, inositol nicotinate, or tryptophan. See the separate listings for these topics.

Niacinamide is used to prevent vitamin B3 deficiency and related conditions such as pellagra. It is also used for acne, diabetes, oral cancer, osteoarthritis, and many other conditions, but there is no good scientific evidence to support these uses.

How does it work ?

Niacinamide can be made from niacin in the body. Niacin is converted to niacinamide when it is taken in amounts greater than what is needed by the body. Niacinamide is easily dissolved in water and is well-absorbed when taken by mouth.

Niacinamide is required for the proper function of fats and sugars in the body and to maintain healthy cells.

Unlike niacin, niacinamide has no beneficial effects on fats and should not be used for treating high cholesterol or high fat levels in the blood.
