Description
NAD+ is nicotinamide adenine dinucleotide, a coenzyme present in all living cells, formed from nicotinamide mononucleotide and adenosine monophosphate joined by a pyrophosphate bridge — a dinucleotide rather than a peptide. This 1000 mg refill cartridge holds the same coenzyme in a format compatible with the reusable metal dispensing pen.
