Niacin is a water-soluble vitamin, also known as vitamin B3 or nicotinamide. Niacin is a precursor to the most central electron carrier substances in living cells, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), thus functioning in many metabolic pathways 1. Foods that contain niacin include beans, liver, fish, poultry and cereal grains.
The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 20 mg niacin for adults and children 4 or more years of age (21CFR101.9).

RDIs serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels.
