Nicotinamide aka Vitamin B3 (niacinamide, nicotinic acid amide) is the pyridine 3 carboxylic acid amide form of niacin. It is a water‑soluble vitamin that is not stored in the body. The main source of vitamin in diet is in the form of nicotinamide, nicotinic acid, and tryptophan. The main source of niacin include meat, liver, green leafy vegetables, wheat, oat, palm kernel oil, legumes, yeast, mushrooms, nuts, milk, fish, tea, and coffee.The recommended daily dose of vitamin B3 in niacin equivalent is given in Table 1.
Nicotinamide is a component of coenzyme I (nicotinamide adenine dinucleotide, NADP) and coenzyme II (nicotinamide adenine dinucleotide phosphate, NADP). The nicotinamide part of these two coenzyme structures in human body has reversible hydrogenation and dehydrogenation characteristics, It plays a hydrogen transfer role in biological oxidation, can promote tissue respiration, biological oxidation process and metabolism, and is of great significance to maintain the integrity of normal tissues, especially skin, digestive tract and nervous system. When lacking, pellagra is caused by the influence of cell respiration and metabolism.
