What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It shuttles electrons through metabolic pathways and serves as a substrate for hundreds of enzymes, including the sirtuins and PARPs involved in gene regulation and DNA repair. Cells hold it in two forms: NAD+, the oxidized form that accepts electrons, and NADH, the reduced form that carries them.

Our vial contains the oxidized form as a lyophilized powder in a 10 mL vial for laboratory research. Buffered versions are also available, such as Buffered NAD+ 500mg. Identity is confirmed by LC-MS at 663.43 g/mol, and every lot is screened for endotoxins. Shop NAD+ for research use.
