What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide — injectable coenzyme research compound) is the oxidised form of NAD, the essential coenzyme involved in over 500 enzymatic reactions in human metabolism — MW 663.4. Injectable NAD+ bypasses oral breakdown and provides direct systemic availability. NAD+ is the primary substrate for sirtuins (SIRT1–7), PARPs (DNA repair), and CD38 — central to mitochondrial energy metabolism, DNA repair, circadian rhythm regulation, and cellular stress response. Intracellular NAD+ declines with age.
Research Applications

Mitochondrial Biogenesis
SIRT1/PGC-1α axis and SIRT3 mitochondrial protein deacetylation — mitochondrial function research
Cellular Senescence & Aging
Age-related NAD+ decline and restoration — senolytics and longevity research models
Circadian Rhythm Regulation
NAMPT-NAD+-SIRT1 feedback loop in circadian clock gene expression
