What it is
NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a pyridine nucleotide cofactor used by cells in redox reactions and as a substrate for enzymes such as sirtuins and PARPs. It is not a peptide. It is supplied here as a lyophilized research material in amber glass, not as an infusion product or a wellness drip.
Research focus
The literature places NAD+ in metabolic and aging biology: mitochondrial redox state, NAD+/NADH ratio, sirtuin activity and related models of cellular energy. These are research territories, not outcomes a visitor should expect. Published papers examine NAD+ as a cofactor and as a declining metabolite with age in many tissues. This page documents the material on file. It does not instruct use.
