NAD+ (Buffered) 500mg
Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme present in all living cells, functioning as an essential electron carrier in mitochondrial oxidative phosphorylation and as a substrate for sirtuins (SIRT1-7), PARPs, and CD38/CD157 ectoenzymes. NAD+ levels decline with age in multiple tissues in preclinical models, a decline studied in relation to mitochondrial dysfunction and impaired DNA repair. This buffered lyophilized formulation is intended for research applications requiring direct NAD+ addition. Supplied strictly for in-vitro research and laboratory use only. Not for human or animal use.

Mechanism of Action
NAD+ serves as a substrate for three major enzyme families: (1) Sirtuins — NAD+-dependent deacetylases that regulate mitochondrial biogenesis, DNA repair, inflammation, and metabolic adaptation; (2) PARPs — DNA damage repair enzymes that consume NAD+ during poly(ADP-ribosyl)ation; (3) CD38/CD157 — ectoenzymes involved in calcium signaling. Camacho-Pereira et al. found that CD38 was required for age-related NAD+ decline in the mouse tissues they studied, with mitochondrial effects linked partly to SIRT3. The cited restoration studies concern NMN/NR precursors or CD38 deletion in mice; they do not establish those whole-organism findings for direct addition of this NAD+ formulation.
