Primary Pathway Salvage Pathway Direct Cellular Uptake Typical Oral Dose 250-1000 mg/day 100-1000 mg/day N/A (not oral) Bioavailability Good (Oral) Excellent (Direct) Speed of Action Moderate Rapid Research Fo…
IV NAD+ 250–1000mg per session Weekly or twice weekly 30–60 minutes 100% (direct infusion) Highest peak concentration but shortest duration. Best for acute interventions or weekly maintenance; impractical for …
This table summarizes the key differences between NAD+ administration routes and their implications for research protocol design. | Administration Route | Bioavailability | Onset Time | Peak Plasma NAD+ | Effe…

Nicotinamide Riboside (NR) 250–500mg daily Moderate (oral capsule) 40–60% at 500mg Strong. Multiple RCTs in humans Best-supported precursor for systemic NAD+ elevation; enzyme saturation above 750mg limits ben…
Oral NAD+ precursors. Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). Enter cells and convert to NAD+ via the salvage pathway. NR requires one enzymatic step (nicotinamide riboside kinase), w…
NMN (oral) 250–500mg daily Moderate (15–30% systemic) 30–60 minutes 8-OHdG reduced 18–25%, gamma-H2AX foci reduced 20–34% in split-dose trials Most studied precursor with consistent human trial data; split dos…
Before choosing a precursor and dose, understand how they differ in bioavailability, cost-effectiveness, and evidence base for neuronal uptake. Nicotinamide Riboside (NR) 250–500mg SLC52A2/A3 transporters; con…
1mL bacteriostatic water 100mg/mL 0.25mL (25 units) 0.5mL (50 units) 1.0mL (100 units) 2 doses High concentration. Ideal for large single doses, minimal injection volume, fastest to exhaust vial 2mL bacteriost…
Springfield 10-Day Protocol 1000mg IV daily × 10 days 500mg IV every 14 days × 12 weeks 13 weeks Case series (n=47) showed 79% completion rate, 21% relapse at 90 days Most aggressive loading. Best for severe a…
NMN (oral) 500–900mg/day split-dose Direct Preiss-Handler entry High (crosses BBB via nucleoside transporters) Phase 2 data in Parkinson's, MCI Best-supported option for neurodegeneration. Superior CNS biomark…
Subcutaneous Injection 250–500mg per session, 2–3×/week 85–90% 30–45 minutes 8–12 weeks at 250mg twice weekly Highest efficiency, requires injection skill, best for acute decline Sublingual NMN/NR 500–750mg da…
Sublingual NMN 250–500mg daily (split dose) 60–75% 15–20 minutes 30–40% at 500mg Highest bioavailability; best supported by mitochondrial function trials Oral NMN (capsule) 400–600mg daily 12–18% 45–90 minutes…
Standard Oral NR 300mg once daily Gelatin capsule 3-5% (~15mg absorbed) Minimal NAD+ elevation; insufficient for measurable metabolic impact in most adults Ineffective for metabolic optimisation. Bioavailabili…
Oral NAD+ (standard capsules) 100–500mg <5% Not achieved N/A Ineffective. NAD+ degrades in GI tract before absorption. Use precursors instead. Oral NMN 250–500mg daily 15–35% 30–45 minutes 6–8 hours Most cost-…
NR 500mg twice daily 1000mg NR Week 1: 250mg once daily; Week 2–3: 250mg twice daily; Week 4+: 500mg twice daily 4–6 hours Moderate. 20–25% experience transient nausea during titration $80–120 Strong. Multiple…
The best NAD+ dosage for addiction recovery in 2026 follows a two-phase structure: acute high-dose loading during detox and withdrawal, followed by lower-dose maintenance infusions to sustain neurological repa…
Sublingual NMN 250–500mg daily NMN → NAD+ (1-step via NMNAT) 60–90 minutes 90 min – 4 hours post-dose Bypasses hepatic first-pass; highest peak tissue NAD+ Best for acute SIRT1/SIRT3 activation studies; fasted…
