NAD+
An essential coenzyme present in every living cell that drives energy metabolism, DNA repair, and sirtuin-mediated longevity pathways.
NAD+ (nicotinamide adenine dinucleotide) is a critical coenzyme that participates in over 500 enzymatic reactions including mitochondrial energy production, DNA repair, and epigenetic regulation. Cellular NAD+ levels decline by approximately 50% between ages 40 and 60, contributing to metabolic dysfunction and age-related disease. Supplementation via IV infusion or oral precursors (NMN, NR) has been shown to restore blood NAD+ levels and is being actively investigated across 30+ clinical trials.
⚙️ Mechanism of Action
NAD+ serves as the primary electron carrier in mitochondrial oxidative phosphorylation, directly fueling ATP production. It is also the essential substrate for sirtuins (SIRT1-7), a family of deacetylase enzymes that regulate gene expression, mitochondrial biogenesis, and cellular stress responses. Additionally, NAD+ powers PARP enzymes critical for DNA repair, and its depletion with age creates a cascade of metabolic and genomic instability.
✅ Benefits
- •Supports mitochondrial energy production (ATP synthesis)
- •Activates sirtuin longevity pathways
- •Enhances DNA repair via PARP enzymes
- •May improve cognitive clarity and reduce brain fog
- •Supports healthy aging and metabolic function
- •Well-tolerated safety profile in clinical trials
⚠️ Risks & Considerations
- •Flushing and warmth with IV administration
- •Nausea and headache during infusions
- •Chest tightness (transient, dose-dependent)
- •Mild GI discomfort with oral precursors
