What It Is
NAD+ is an essential coenzyme in cellular energy metabolism, serving as an electron carrier in mitochondrial oxidative phosphorylation (complex I, III, IV). It activates sirtuins (SIRT1-7) which regulate gene expression, DNA repair, circadian rhythm, and mitochondrial biogenesis. NAD+ is consumed by PARP enzymes for DNA repair and by CD38 for calcium signaling. When administered exogenously (IV or subcutaneous), NAD+ raises intracellular NAD+ levels, improving mitochondrial function, cellular energy production, oxidative stress resilience, and neurological function. Subcutaneous and IV administration are more effective than oral precursors (NMN, NR) at rapidly raising blood NAD+ levels.
Supplies Needed
Diluent for IV infusion
Reconstitution solvent
IV administration setup
Subcutaneous administration
Storage
Store at -20C protected from light. NAD+ is sensitive to light and heat - store carefully.
Refrigerate at 2-8C; use within 24-48 hours once reconstituted. NAD+ in solution degrades relatively quickly.

Dosing Protocols
Timing: Morning. Subcutaneous is a gentler alternative to IV; start low to assess tolerance and flushing
↓ Apply these values to the reconstitution calculatorTiming: Morning. IV provides fastest and highest NAD+ elevation; subcutaneous for maintenance between IV sessions
↓ Apply these values to the reconstitution calculatorTiming: Morning. High-dose IV NAD+ used for addiction recovery, neurological conditions, and intensive anti-aging protocols

| Week | Expected Effects |
|---|---|
| Week 1 | Improved energy and mental clarity; particularly notable after IV infusion |
| Week 2 | Reduced fatigue; improved cognitive function and working memory |
| Week 4 | Sustained energy improvement; improved sleep quality; possible mood enhancement |
| Week 12 | Cumulative sirtuin activation benefits; mitochondrial function improvements; anti-aging cellular benefits |

Injection Technique & Reconstitution
- For subcutaneous use: Remove flip-top cap from vial
- Swab rubber stopper with alcohol swab
- Draw sterile 0.9% saline or bacteriostatic water into syringe
- Inject slowly down the vial wall
- Gently swirl until dissolved - solution should be clear
- For IV use: dissolve in 250 mL 0.9% saline for slow drip (over 1-2 hours minimum)
- Label with date; refrigerate at 2-8C
- IV administration should be performed slowly to avoid flushing, nausea, and chest tightness

Mechanism of Action
NAD+ is an essential coenzyme in cellular energy metabolism, serving as an electron carrier in mitochondrial oxidative phosphorylation (complex I, III, IV). It activates sirtuins (SIRT1-7) which regulate gene expression, DNA repair, circadian rhythm, and mitochondrial biogenesis. NAD+ is consumed by PARP enzymes for DNA repair and by CD38 for calcium signaling. When administered exogenously (IV or subcutaneous), NAD+ raises intracellular NAD+ levels, improving mitochondrial function, cellular energy production, oxidative stress resilience, and neurological function.

5-Amino-1MQ inhibits NNMT (prevents NAD+ degradation) while direct NAD+ supplementation provides substrate - additive effect on intracellular NAD+ levels.
Anti-aging synergy - NAD+ activates sirtuins and improves mitochondrial function while Epithalon extends cellular lifespan via telomerase activation.
Frequently Asked Questions
NAD+ is used to restore declining coenzyme levels associated with aging, improve mitochondrial energy production, activate anti-aging sirtuins, improve cognitive function, and aid addiction recovery. IV NAD+ is particularly popular in longevity clinics.
IV and subcutaneous NAD+ raise blood NAD+ levels most rapidly and directly. NMN and NR require intracellular conversion steps but are effective at raising NAD+ with regular oral supplementation. IV is best for acute high NAD+ elevation; oral precursors for daily maintenance.
NAD+ must be infused slowly (over 1-2+ hours) to avoid side effects including chest tightness, flushing, nausea, and palpitations. These side effects are rate-dependent and resolve when the infusion is slowed.
