NAD+ (Nicotinamide Adenine Dinucleotide)

moderateResearch Use OnlyInjection

Critical molecule for cellular energy and DNA repair. Levels may drop ~50% by middle age. Activates sirtuin longevity genes and powers PARP DNA repair enzymes. Injectable form bypasses oral absorption issues.


Key facts
Classification
NAD+ is a critical coenzyme in redox reactions and substrate for sirtuins, PARPs, and CD38.

Scientific overview

NAD+ is a critical coenzyme in redox reactions and substrate for sirtuins, PARPs, and CD38. Intracellular levels may decline substantially between ages 40-60. Exogenous supplementation bypasses the NAMPT rate-limiting step, improving mitochondrial membrane potential, energy production, and DNA repair capacity.
