Understanding NAD+: The Cellular Energy Currency
What is NAD+?
NAD+ is a coenzyme that exists in every cell of your body and is essential for:
- Energy production: NAD+ is crucial for mitochondrial function, driving ATP production to fuel all cellular activities
- DNA repair: Required for the activation of PARPs (poly ADP-ribose polymerases), enzymes that detect and repair DNA damage
- Metabolic regulation: Plays a vital role in regulating glucose and lipid metabolism, promoting efficient energy use
- Cellular health: Activates sirtuins, proteins that regulate cellular health, reduce inflammation, and improve resilience
Why NAD+ Levels Decline
As we age, NAD+ levels naturally decrease due to:
- Increased consumption by NAD+-consuming enzymes
- Reduced biosynthesis efficiency
- Chronic inflammation and oxidative stress
- Accumulated DNA damage requiring more NAD+ for repair
By age 50, NAD+ levels can be approximately 50% lower than in youth, contributing to reduced energy, slower recovery, and accelerated aging processes.

Methods of NAD+ Administration: A Comprehensive Comparison
Not All NAD+ Delivery Methods Are Created Equal
The method of administration significantly impacts bioavailability, cost-effectiveness, and clinical outcomes. Here's what you need to know:
1. At-Home NAD+ Injections (Subcutaneous) ⭐ RECOMMENDED
Uptake: High ✅ (measured dosing over time provides excellent absorption)
Value: 🏆 Best Overall (strong performance, sustained benefits taken several times a week, lower price than infusions)
Cost: $150-450/month depending on dosing
Convenience: Great - at home, 2-5 times per week
Clinical Notes:
- Provides steady, sustained elevation of NAD+ levels
- Measured dosing allows for flexible scheduling
- Can spread smaller doses throughout the week to maximize uptake
- Ideal for performance, longevity, and mitochondrial support
- Recommended dose: 1000mg/month minimum for therapeutic effects
Best for: Individuals seeking consistent benefits, cost-effectiveness, and convenience of home administration
2. IV NAD+ Drip (Intravenous)
Uptake: Highest ✅⭐ (rapid spike, but blood NAD+ is cleared in ~4 hours; cellular effects can last days to weeks)
Value: ❌ Low-Moderate (immediate but short-lived effects; expensive, requires multiple visits)
Cost: $250-900 per session (250mg-1000mg per session)
Convenience: Worst - requires clinic visits, 1-3 hours per session
Clinical Notes:
- Provides immediate, dramatic spike in blood NAD+ levels
- Blood levels return to baseline within ~4 hours
- Cellular benefits may persist for days to weeks
- Ideal for acute energy or recovery boosts
- Best option for severe immune challenges
- Most expensive option per milligram
Best for: Acute situations requiring immediate intervention, special events, or those with significant health challenges
3. Oral Supplements (NMN and NR)
Uptake: 💊 Low-moderate (relies on conversion to NAD+)
Value: Decent low-cost option for daily support
Cost: $35-100/month
Convenience: Easiest - daily supplement
Clinical Notes:
- NAD+ breaks down in digestion when not injected
- Supplements rely on precursors (NMN, NR) which help cells make NAD+
- Conversion efficiency varies significantly between individuals
- Clinical and anecdotal results not as significant as injections or IV
- Requires consistent daily use
- Best as maintenance or complement to other methods
Best for: Those seeking affordable daily support or who cannot tolerate injections
4. Nasal Spray
Uptake: Medium (mostly cognitive effects)
Value: 🏆 Great for specific cognitive applications
Cost: $$$ (typically premium pricing)
Convenience: Great - at home, as needed
Clinical Notes:
- Absorbs through nasal mucosa for rapid delivery
- More targeted to brain and cognitive function
- Limited systemic distribution compared to injections
- Useful for acute cognitive enhancement needs
Best for: Cognitive performance, focus, and mental clarity needs
Side-by-Side Delivery Method Comparison
| Method | Overall Value | Cost | Uptake | Convenience | Best Use Case |
|---|---|---|---|---|---|
| NAD+ Injections | 🏆🏆🏆 WINNER | $$ | High, steady benefits | Great: At home 2-5×/wk | Long-term optimization, best value |
| IV NAD+ Drip | 🏆🏆 | $$$$ | Highest, but short-lived | Worst: Clinic visits, 1-3 hrs | Acute recovery, severe challenges |
| NMN/NR Supplements | 🏆 | $ | Low-Medium, less felt effects | Easiest: Daily supplement | Daily maintenance, budget option |
| Nasal Spray | 🏆 | $$$ | Medium, mostly cognitive | Great: At home as needed | Cognitive enhancement |
Provider Comparison: Finding the Best Value
Price Per Milligram Analysis
When evaluating NAD+ injection providers, the most important COST metric is price per milligram including all fees (shipping, supplies, consultation, and provider support).
We also know that service, transparency, trusted pharmacies, communication, flexibility and more are also important when choosing a provider, for but for many people, cost is still king, so we will focus on that.
NAD+ Injections Price Comparison
| Provider | Milligrams NAD+ | Price | Price/mg |
|---|---|---|---|
| Levers | 2000mg | $297 | $0.15 |
| Joi + Blokes | 1000mg | $400* | $0.40 |
| AgelessRx | 1000mg | $395 | $0.40 |
| Drip Hydration | 1000mg | $299 | $0.30 |
*Sold as a "10-week" NAD+ plan without disclosing it's only 1000mg total, or just 100mg/week
Important Note: Consider sourcing, service, and overall price per milligram for NAD+ at-home injections. Flexibility and transparency are also very important.
Buyer beware: Many providers will also lock you into a subscription with a low introductory rate, but will only provide you 250mg or 500mg of NAD+ for the first few months, not providing more NAD+ until you're at a higher dosing.

Dosing Recommendations
Know Your Dose
Based on clinical evidence and practitioner recommendations:
- Maintenance/Prevention: 500-1000mg/month
- Therapeutic/Optimal: 1000-2000mg/month
- Performance/Intensive: 2000mg monthly
Important: Many providers don't clearly disclose the total milligrams you're receiving. Always calculate the actual NAD+ content:
- Some "10-week programs" provide only 1000mg total (100mg/week), below therapeutic thresholds
- Levers clearly states milligrams: 1200mg or 2000mg plans
Flexible Dosing with Injections
One advantage of at-home injections is dosing flexibility:
- Spread doses throughout the week (e.g., 200mg 2-3× weekly)
- Adjust based on your activity level and recovery needs
- Smaller, frequent doses may maximize cellular uptake
