Nicotinamide is a watersoluble vitamin, The product is white crystalline powder, odorless or nearly odorless, bitter in taste, freely soluble in water or ethanol, dissolvable in glycerin.
Nicotinamide is easy to absorb oral, and can be widely distributed in the body, the excess metabolites or prototype quickly expel from urine. Nicotinamide is part of coenzyme I and coenzyme II, plays the role of hydrogen delivery in biological oxidation respiratory chain, can promote biological oxidation processes and tissue metabolism, maintain normal tissue (especially the skin, digestive tract and nervous system) integrity has an important role.
