NAD+ Injection Dosage Per Day: Chart, Timing and Safety
NAD+ injection dosage per day ranges from 50mg to 1,000mg depending on your overall health goals and current cellular energy status.
Clinical protocols start most people at 50-100mg injections administered 2-3 times per week for general wellness. Your specific needs depend on your health goals and current NAD levels. Doses above 200mg require medical supervision to prevent adverse effects and liver stress.
Daily NAD Injection Dosage Chart and Protocols
Daily NAD+ injection dosage varies from 50mg for wellness to 1,000mg for addiction recovery protocols under medical supervision.
Standard Dose Ranges by Health Goals
Clinical protocols establish specific dosages for 5 main therapeutic applications including general wellness, loading phases, and addiction recovery.
Health Goal | Daily Dose Range | Frequency | Duration |
---|---|---|---|
General Wellness | 50-100mg | 2-3x per week | Ongoing |
Loading Phase | 100-200mg | Daily | 7-10 days |
Athletic Recovery | 200-500mg | 2-3x per week | 2-4 weeks |
Cognitive Enhancement | 100-250mg | 1-2x per week | 4-6 weeks |
Addiction Recovery* | 500-1,000mg | Daily | 7-10 days |
*Requires medical supervision
Your cellular energy needs change based on stress levels, exercise intensity, and age-related decline. NAD levels naturally decline with age, dropping approximately 50% every 20 years after age 401.
Conservative doses minimize potential side effects while your cellular function adapts to increased NAD availability.
Loading Phase vs Maintenance Protocol
The loading protocol saturates depleted cellular reserves with 100-200mg daily injections for 7-10 consecutive days.
Maintenance dosing maintains stable levels with 50-100mg injections administered 1-2 times per week for ongoing cellular health support.
Healthcare providers monitor your response during loading phases through blood work that tracks metabolic responses to higher NAD concentrations.

IV Drip vs Injection: Understanding Your Options
IV drip and subcutaneous injections both deliver NAD directly into your bloodstream, bypassing digestive breakdown for immediate cellular uptake.
IV Therapy Administration Methods
NAD IV therapy delivers 250mg to 1,000mg per session through slow infusion over 2-4 hours in clinical settings.
Extended infusion time allows cellular NAD absorption without rapid administration side effects like nausea and flushing.
IV sessions cost $300-800 each and require 4-10 clinic sessions over several weeks according to standard protocols.
Subcutaneous Injections vs Other Routes
Subcutaneous injections (sometimes called NAD shots) offer more convenience and lower costs. You inject NAD into fatty tissue under your skin, typically in your abdomen or upper arm.
These injections take 30-60 seconds to administer. The injection site may experience mild redness or swelling that resolves within hours.
Many people prefer subcutaneous injections because you can:
- Self-administer after proper training
- Use smaller volumes (1-2ml vs 250-500ml for IV)
- Avoid lengthy clinic appointments
- Pay less per dose
Timing and Frequency for Optimal Results
Morning injections provide optimal results because NAD boosts cellular energy production without interfering with sleep cycles.
Best Times Per Week for Injections
Morning administration prevents sleep interference from NAD’s energizing effects on cellular metabolism.
Injection frequency follows these 3 patterns:
- 2-3 times per week: Allows cellular recovery between doses
- Every other day: Supports loading phases
- Weekly: Maintains levels in sensitive individuals
Your qualified healthcare professional can help personalize the timing based on your energy patterns and health status.
Dosage and Frequency Considerations
Cellular NAD processing capacity limits optimal dosing, making higher doses counterproductive and potentially hepatotoxic.
Dosage and frequency follow these established patterns:
- Higher doses: Require longer intervals between injections
- Lower doses: Allow more frequent administration
- Loading doses: Use daily administration for 7-10 days maximum
Dose schedules account for natural NAD recycling processes that maintain consistent cellular energy rather than dramatic fluctuations.
Potential Health Benefits and Cellular Impact

NAD injections target cellular mechanisms that decline with age and stress through direct mitochondrial function support.
Cellular Energy Production
NAD serves as an essential cofactor in mitochondrial ATP production, converting nutrients into usable cellular energy.
Wellness clinics often claim these NAD injection effects:
- Energy level increases within hours of administration
- Mental clarity and cognitive function improvements
- Healthy aging process support
- Better exercise recovery and performance
The benefits of NAD appear with consistent dosing over weeks rather than single injections.
Mitochondrial Function and DNA Repair
NAD’s role in cellular health extends beyond energy production. NAD activates sirtuins, proteins that repair DNA damage and regulate cellular stress responses.
These processes support:
- Reduced cellular inflammation
- Better stress resilience
- Improved metabolic flexibility
- Enhanced cellular repair mechanisms
Age-related medical conditions often involve NAD depletion. Restoring adequate levels through injection can help reverse some cellular dysfunction, though individual results vary significantly.
Safety Guidelines and Healthcare Provider Oversight
NAD injection risks increase proportionally with dosage and poor administration technique.
Common Side Effects at Injection Site
Injection sites experience these 4 common reactions lasting 2-4 hours:
- Redness and swelling lasting 2-4 hours
- Mild pain or tenderness when touched
- Small bruising in sensitive individuals
- Temporary warmth or tingling sensation
Rotating injection sites prevents irritation buildup. Clean technique prevents infections that could cause serious complications.
Systemic side effects include nausea, flushing, and headaches. These typically occur with doses above 200mg and resolve within 1-2 hours.
Medical Supervision Requirements
Higher doses require monitoring to catch problems early. Your healthcare provider should track:
Monitoring | Frequency | Why Important |
---|---|---|
Liver function tests | Every 3-6 months | Detects enzyme elevation |
Blood pressure | Each visit | NAD can lower BP |
Injection site assessment | Each administration | Prevents complications |
Symptom tracking | Ongoing | Identifies adverse reactions |
Never exceed 1,000mg daily without medical supervision. These doses can overwhelm your liver’s processing capacity and cause serious complications.
Understanding NAD IV therapy side effects helps you recognize when to seek medical attention vs normal treatment responses.
Safer Alternatives: Why Oral Supplementation Wins
While injections deliver NAD directly to your bloodstream, they come with significant drawbacks compared to high-quality oral supplements.
Our Vitality NAD powder supplement offers a safer, more convenient approach to raising your NAD levels. This powder supplement contains a clinically validated blend of NMN, creatine, D-ribose, and niacinamide that work together to boost cellular energy production.
Advantages over injections:
- No injection site reactions or infection risk
- Lower cost per dose over time
- Easy daily use without clinic visits
- Proven effective in numerous clinical studies2
- Gradual NAD increase that’s gentler on your system
- Can combine with our Intracellular NAD Test to track progress
The powder format allows you to adjust your dose gradually. Start with half a scoop daily and increase based on your energy response and NAD testing results.
When comparing NAD supplements vs IV therapy, oral supplementation provides sustained NAD support without the risks and inconvenience of repeated injections.
The Bottom Line
NAD injection dosage per day ranges from 50mg for wellness to 1,000mg for medical applications, with conservative starting doses under medical supervision providing optimal safety and efficacy. High-quality oral supplements like our Vitality NAD+ Booster offer safer, more practical long-term cellular energy support than repeated injections.
