NAD is the abbreviation of Nicotinamide Adenine Dinucleotide. NAD powder is easy to dissolve in water, insoluble in acetone or other organic solvents. NAD exists in two forms: oxidized form NAD+ and reduced form NADH. NAD+ is like a carrier in the energy production process, however nadh carries crucial electrons and hydrogen. In metabolism, NAD is a cofactor, involved in redox reactions, by carrying electrons from one reaction to another.

NAD powder is helpful for improving metabolism. It can potentially prolong the lifespan of cells, thus it may have anti-aging effect. NAD powder can be used in supplements, and it is also be used in pharmaceuticals.
