Nicotinamide Adenine Dinucleotide
Also known as: NAD+, NAD, Coenzyme I
NAD+ is a fundamental coenzyme in cellular energy metabolism, serving as the primary electron carrier in mitochondrial oxidative phosphorylation and as an essential substrate for sirtuins (SIRT1-7), PARPs, and CD38/CD157 enzymes. NAD+ levels decline significantly with age, impairing sirtuin-mediated gene regulation, mitochondrial function, and DNA repair capacity. The 500mg product contains the s...

Key research categories and applications studied in the scientific literature.
Cognitive Enhancement
NAD+ boosts cellular energy, reducing brain fog and supporting overall mental clarity. Sirtuin activation in neurons supports synaptic plasticity and neuroprotection.
Anti-Aging & Longevity
NAD+ decline is now considered a hallmark of aging. Restoring NAD+ levels in aged animal models reverses metabolic decline, improves muscle strength, and extends lifespan.
Cellular Energy & DNA Repair
Essential coenzyme for 500+ enzymatic reactions including energy production, PARP-mediated DNA repair, and sirtuin-dependent gene regulation.
Mitochondrial Function
NAD+ is required for mitochondrial electron transport chain function. Age-related NAD+ decline impairs mitochondrial capacity, and restoration reverses this decline in preclinical models.
Frequently Asked Questions
Common questions about nad+ research research, purity standards, and sourcing.
What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell, essential for over 500 enzymatic reactions including cellular energy production, DNA repair, gene expression regulation, and calcium signaling. NAD+ levels decline with age, and this decline is now considered a hallmark of aging.
Why does NAD+ decline matter for aging?
NAD+ decline impairs sirtuin activity (SIRT1-7), reduces PARP-mediated DNA repair capacity, decreases mitochondrial function, and promotes cellular senescence. Restoring NAD+ levels in aged animal models reverses many of these age-related declines, improving metabolic function, muscle strength, and lifespan.
How does NAD+ activate sirtuins?
Sirtuins (SIRT1-7) are NAD+-dependent deacetylases that regulate gene expression, DNA repair, metabolism, and stress responses. They require NAD+ as a co-substrate — when NAD+ levels fall, sirtuin activity decreases proportionally, reducing the cell's ability to maintain homeostasis and resist stress.
