NAD+

🔬What Is NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in every living cell, essential for over 500 enzymatic reactions including cellular energy production, DNA repair, gene expression regulation, and cellular signaling. NAD+ levels naturally decline by approximately 50% between ages 40 and 60, contributing to metabolic dysfunction, cognitive decline, and accelerated aging. It serves as a substrate for key enzymes including sirtuins (SIRT1-7), PARPs (poly-ADP-ribose polymerases), and CD38. Research published in Science and Cell Metabolism demonstrates that restoring NAD+ levels reverses many hallmarks of aging, improves mitochondrial function, enhances DNA repair capacity, and activates sirtuin-mediated longevity pathways.

📊Clinical Studies & Results

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme studied extensively in aging, cellular metabolism, and neuroprotection:

• ▪Randomized controlled trial with 80 middle-aged adults demonstrated NMN supplementation (600mg/day) significantly increased blood NAD+ levels and improved physical performance including walking endurance over 60 days (Yi et al., Geroscience, 2023; PMID: 36482258)
• ▪Pilot clinical trial showed nicotinamide riboside improved vascular endothelial function and cognitive performance in older adults with peripheral artery disease (PMID: 40479886)
• ▪NAD+ precursor supplementation reliably increased intracellular NAD+ concentrations in human tissues, with tissue-specific effects on metabolic and mitochondrial function (Vinten et al., Nat Metab, 2025)
• ▪Studies demonstrated NAD+ activates all seven sirtuin enzymes (SIRT1-7), which regulate DNA repair, inflammation, mitochondrial biogenesis, and circadian rhythm (Imai & Guarente, Trends Cell Biol, 2014; PMID: 24786309)
• ▪NAD+ depletion was shown to impair PARP-mediated DNA repair capacity, with supplementation restoring genomic integrity in aging cells (Fang et al., Cell Metab, 2016; PMID: 26686024)

NAD+ supplementation is one of the most evidence-supported interventions in longevity science, with demonstrated effects on cellular energy, DNA repair, and systemic metabolic optimization.
