- Sublingual NAD+
- None (direct)
- 250–500mg twice daily
- 4–6 hours
- $180–$300
- Fastest activation, highest bioavailability, requires refrigeration. Best for acute protocols
- NMN (nicotinamide mononucleotide)
- One (via NMNAT)
- $80–$150
- Optimal balance of cost, efficacy, and stability. Recommended for most DNA repair protocols
- NR (nicotinamide riboside)
- Two (NRK1/2, then NMNAT)
- 300–600mg twice daily
- 3–5 hours
- $60–$120
- Well-studied, lower conversion efficiency, requires higher doses. Cost-effective option
- Liposomal NAD+
- 200–400mg twice daily
- 5–8 hours (extended)
- $150–$250
- Improved pharmacokinetics, limited clinical data, premium pricing
- NAD+ IV infusion
- None (direct, bypasses GI)
- 250–500mg per session
- 6–10 hours
- $200–$400 per session
- Highest acute bioavailability, impractical for daily use, clinical setting required
