NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, functioning as a critical electron carrier in cellular respiration and as a substrate for multiple enzyme families central to cellular homeostasis. Its roles span glycolysis, the TCA cycle, oxidative phosphorylation, sirtuin activation, PARP-mediated DNA repair, and CD38-mediated signalling.
NAD+ has become one of the most actively researched compounds in longevity biology due to its well-documented decline with age and its central position in multiple ageing-associated biochemical pathways.
NAD+ is the obligate substrate for sirtuin deacylase enzymes (SIRT1–7), which regulate gene expression, stress response, mitochondrial function, and metabolic adaptation. NAD+ availability directly determines sirtuin activity levels — making it the key regulator of this broadly studied enzyme family.
Poly-ADP-ribose polymerases (PARPs) consume NAD+ during the DNA damage response. NAD+ is used in studies examining DNA repair kinetics, PARP enzyme activity, and the metabolic cost of DNA damage response activation.
As the central electron carrier in the main energy-generating pathways, NAD+ is foundational to cellular bioenergetics research — from glycolytic flux to oxidative phosphorylation efficiency.
The documented decline of NAD+ levels with age has generated intense research interest. Cell studies investigating NAD+ supplementation effects on mitochondrial function, sirtuin activity, and age-related metabolic phenotypes are among the most active areas of longevity biology research.
NAD+ is the endpoint of the NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) biosynthesis pathways. Researchers often study NAD+ directly alongside its precursors to map the salvage biosynthesis pathway and its regulation.
NAD+ 500mg is available from Nova Biolabs at £40, from UK domestic stock. HPLC-verified at >98% purity.
The relationship between NAD+ and mitochondrial function is one of the most active research areas in current cell biology. NAD+ availability affects mitochondrial membrane potential, respiratory chain complex activity, and ATP production efficiency — all critical parameters in mitochondrial research models. For complementary mitochondrial research tools, see also MOTS-C and SS-31, both also stocked by Nova Biolabs.
All Nova Biolabs peptides are research grade, HPLC-verified and held in UK stock for same or next-day dispatch.
