Niacin is a water-soluble vitamin that is passed through urine, which means people need a steady supply of it in their diet. Niacin plays an important role in lowering cholesterol, processing fat and regulating blood glucose levels in the body. When a diet is deficient in niacin, pellagra can occur.
