Niacin (vitamin B3) Facts

Vitamin B3, also called niacin, is a water-soluble B-vitamin that the body uses to release energy from food and to support hundreds of biochemical reactions. It is naturally found in foods such as poultry, fish, whole grains, legumes, and some vegetables, and can also be formed in the body from the amino acid tryptophan. Because the body uses it continuously and does not store large amounts, ensuring consistent intake is important.
