Coenzyme · Cellular Metabolism
NAD+
Cellular energy, longevity pathway
Mechanism
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme central to redox reactions in every cell. It is a required substrate for sirtuins (SIRT1–7) and PARPs, which regulate DNA repair, gene expression, and mitochondrial biogenesis. Parenteral NAD+ bypasses gut conversion inefficiency, delivering the coenzyme directly into circulation.
Indications
Regulatory status
NAD+ is available as an injectable via 503A compounding pharmacies. It is not FDA-approved as a drug but is recognized as a naturally occurring substance with established safety at therapeutic doses.
