Comparison: NAD+ Protocols by Age Decade

30–40 Mild NAMPT decline 250mg NMN daily OR 150mg NR daily Optional. Resveratrol 250mg for SIRT1 support 18–25% Younger individuals can restore NAD+ with single-precursor dosing and minimal co-factor support. The salvage pathway is still efficient 40–50 NAMPT

  • 30–40
  • Mild NAMPT decline
  • 250mg NMN daily OR 150mg NR daily
  • Optional. Resveratrol 250mg for SIRT1 support
  • 18–25%
  • Younger individuals can restore NAD+ with single-precursor dosing and minimal co-factor support. The salvage pathway is still efficient
  • 40–50
  • NAMPT decline + early mitochondrial dysfunction
  • 300–400mg NMN + 150mg NR daily
  • Quercetin 500mg, magnesium 400mg
  • 25–32%
  • This decade marks the shift toward dual-precursor protocols. CD38 inhibition with quercetin becomes measurably beneficial
  • 50–60
  • Severe NAMPT decline + elevated CD38 + inflammation
  • 400–500mg NMN + 200–300mg NR daily
  • Quercetin 500mg, resveratrol 500mg, methylated B-complex
  • 30–38%
  • The enzymatic bottlenecks require aggressive co-factor support and dual-precursor dosing. Single-precursor protocols underperform significantly
  • 60+
  • All above + mitochondrial membrane degradation
  • 500mg NMN + 300mg NR + possible NAD+ IV therapy
  • Quercetin 500mg, pterostilbene 150mg, PQQ 20mg, CoQ10 200mg
  • 28–35% (supplementation alone)
  • At this stage, oral supplementation alone may not suffice. Some patients benefit from periodic NAD+ IV infusions to bypass absorption barriers
