NAD+
NAD+ is a central redox cofactor studied in research involving cellular energy metabolism, mitochondrial function and NAD-dependent enzymes.
Research overview
NAD+ is an endogenous coenzyme central to oxidation-reduction reactions and cellular energy metabolism. It also serves as a substrate for enzymes including sirtuins and PARPs, linking NAD biology to DNA repair, stress responses and metabolic regulation.
Evidence status
NAD biology is well established, but evidence for specific exogenous NAD+ interventions depends heavily on route, population and outcome. Mechanistic importance does not by itself establish a clinical benefit.
Areas under investigation
- Cellular redox and energy metabolism
- Mitochondrial biology
- Sirtuin, PARP and NAD-consuming enzyme pathways
