NAD+ is a coenzyme, a helper molecule that cells need to produce energy. Every living cell contains it. It works by carrying electrons from one reaction to the next. Studies have measured its role in mitochondria, in cell signaling, and in DNA repair. Levels inside cells decline with age across many tissue types.
Pyridine dinucleotide coenzyme
The pathways NAD+ acts on — and what each one does. Signalling pathways studied in preclinical models · illustrative.
NAD+ is essential for mitochondrial electron transport chain function, directly participating in the conversion of nutrients to cellular energy (ATP). Declining NAD+ levels impair mitochondrial efficiency.
NAD+ is the obligate co-substrate for all 7 sirtuin enzymes (SIRT1-7), which regulate aging, inflammation, stress resistance, and metabolic homeostasis. Without NAD+, sirtuins cannot function.
PARP enzymes consume NAD+ to repair DNA damage. As NAD+ declines with age, DNA repair capacity decreases, accelerating cellular senescence and genomic instability.
The main areas NAD+ is being studied for — and the study-reported figures behind them.
NAD+ supplementation extends lifespan in multiple model organisms by activating sirtuin-mediated longevity pathways and improving mitochondrial function.

Declining NAD+ induces a pseudohypoxic state disrupting nuclear-mitochondrial communication. Restoring NAD+ reverses age-related metabolic decline in animal models.

NAD+ fuels PARP enzymes responsible for single-strand DNA break repair. Depletion leads to accumulated DNA damage and accelerated cellular aging.

NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in every living cell. It participates in over 500 enzymatic reactions and is critical for energy metabolism, DNA repair, and cellular signaling. NAD+ levels naturally decline with age, which researchers believe contributes to age-related metabolic dysfunction.
NAD+ levels decline approximately 50% by age 50. This decline impairs mitochondrial function, reduces sirtuin enzyme activity, and compromises DNA repair capacity. Research in animal models shows that restoring NAD+ levels can reverse some markers of age-related decline.
Sirtuins (SIRT1-7) are a family of enzymes that regulate aging, metabolism, inflammation, and stress resistance. They are completely dependent on NAD+ as a co-substrate — without sufficient NAD+, sirtuins cannot function, and their protective effects are lost.
NAD+ is the active coenzyme itself. NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are precursors that cells convert into NAD+. Direct NAD+ supplementation bypasses the conversion steps, while NMN and NR rely on cellular enzymes to produce NAD+.
Lyophilized NAD+ should be stored at -20°C for long-term stability. NAD+ is sensitive to heat and light — always protect the material from direct light.
