NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in all living cells, playing a fundamental role in oxidation-reduction reactions central to cellular energy metabolism. It serves as an electron carrier in the mitochondrial electron transport chain and as a substrate for NAD+-dependent enzymes including sirtuins (SIRTs), poly(ADP-ribose) polymerases (PARPs), and CD38. NAD+ levels have been the subject of significant research interest due to their observed decline with age in various tissue types.

Preclinical research has investigated NAD+ supplementation for its effects on mitochondrial biogenesis, sirtuin-mediated gene regulation, DNA damage response via PARP activation, and cellular energy production. Studies have examined NAD+ in the context of metabolic research, neurological function, cardiovascular biology, and aging research. The NAD+/NADH ratio is widely used as a readout of cellular metabolic state in research settings.

NAD+ is one of the most extensively studied molecules in biochemistry and metabolic research. It is commonly referenced in studies examining mitochondrial function, longevity pathways, caloric restriction mimetics, and sirtuin biology. This 500mg research preparation is intended for laboratory studies requiring substantial quantities for in vitro or preclinical experimental protocols.
