Niacin is both a vitamin, i.e., an essential nutrient, marketed as a dietary supplement, and in the US, a prescription medicine. As a vitamin, it is precursor of the coenzymes [[nicotinamide adenine dinucleotide]] (NAD) and [[nicotinamide adenine dinucleotide phosphate]] (NADP). These compounds are coenzymes for many dehydrogenases, participating in many hydrogen transfer processes. NAD is important in [[catabolism]] of fat, carbohydrate, protein, and alcohol, as well as cell signaling and DNA repair, and NADP mostly in [[anabolism]] reactions such as fatty acid and cholesterol synthesis. Vitamin intake recommendations made by several countries are that intakes of 14–18&nbsp;mg/day are sufficient to meet the needs of healthy adults. Niacin but also [[nicotinamide]] (niacinamide) are used for prevention and treatment of [[pellagra]], a disease caused by lack of the vitamin. When niacin is used as a medicine to treat [[hyperlipidemia|elevated cholesterol and triglycerides]], daily doses range from 500 to 3,000&nbsp;mg/day. High-dose nicotinamide does not have this medicinal effect.</div>FuzzyBot
