Niacin is a B vitamin. It occurs naturally in plants and animals, and is also added to many foods as a vitamin supplement. It is present in many vitamin and nutritional supplements.

Niacin is used to treat and prevent a lack of natural niacin in the body, and to lower cholesterol and triglycerides in the blood. It is also used to lower the risk of heart attack in people with high cholesterol who have already had a heart attack.

Niacin is sometimes used to treat coronary artery disease (atherosclerosis).
