What is niacin?

Niacin, or vitamin B3, encompasses nicotinic acid, niacinamide (also called nicotinamide or nicotinic acid amide) and their derivatives. It plays a role in a variety of metabolic reactions and is necessary for the activity of many enzymes. Niacin occurs naturally in foods such as meat, fish, sunflower seeds and peanuts, as well as in whole grains such as whole wheat and brown rice. The liver can also synthesize niacin from the amino acid tryptophan, a building block for proteins.
