NAD+ Research Guide
Full name: Nicotinamide Adenine Dinucleotide (NAD+ / NMN / NR)
Critical coenzyme declining 50% between ages 40-60. Supplementation via precursors (NMN, NR) or direct NAD+ infusion restores cellular energy, DNA repair, and sirtuin pathways.
How NAD+ Works
NAD+ serves as cofactor for sirtuins (SIRT1-7), PARPs (DNA repair), and CD38. Declining NAD+ impairs mitochondrial function and epigenetic maintenance. Restoration reactivates longevity pathways.
Dosing Protocol
- Typical dose: 250-500mg IV or 500-1000mg NMN oral
- Frequency: Weekly (IV) or Daily (oral)
- Duration: Ongoing
- Route: IV infusion or Oral (precursors)
Reported Benefits
- Restored cellular energy
- Enhanced DNA repair
- Sirtuin activation
- Improved mitochondrial function
- Cognitive clarity
- Anti-aging
Potential Side Effects
- Flushing (IV)
- Nausea
- Headache
- Insomnia if taken late
- GI discomfort (oral)
