Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme found in all living cells, playing a central role in cellular energy metabolism, DNA repair, and the regulation of key biological processes. As a hydride-transferring molecule, NAD+ serves as a critical electron carrier in oxidative phosphorylation and the citric acid cycle, facilitating the conversion of nutrients into adenosine triphosphate (ATP).
Beyond its metabolic function, NAD+ is a substrate for sirtuin deacetylases (SIRT1–SIRT7), PARP enzymes involved in DNA damage response, and cyclic ADP-ribose synthases, making it a focal point in longevity, genomic stability, and circadian rhythm research. Declining intracellular NAD+ levels have been associated with cellular senescence and age-related metabolic dysfunction, driving significant scientific interest in NAD+ repletion strategies.
