October 9, 2025 •

5 min read

Research indicates that Nicotinamide Adenine Dinucleotide (NAD+) levels naturally decline with age and stress, influencing cellular energy and repair. This depletion has led to the popularity of supplemental therapies, prompting many to ask, how often can I get an NAD injection?. The answer is not one-size-fits-all, depending heavily on your individual health needs and goals.

Quick Summary

The frequency for NAD injections varies based on health goals, from anti-aging to chronic fatigue and addiction recovery. Protocols typically involve an initial loading phase, followed by a less frequent maintenance schedule. Personal factors, lifestyle, and medical consultation are key to determining the right approach.

Key Points

Initial Loading Phase: A loading period often involves more frequent injections (1-2 times weekly for 4-6 weeks) to restore depleted NAD+ levels.
Maintenance Phase: After the initial period, frequency typically reduces to once every 1-4 weeks to sustain benefits for general wellness.
Personalized Plan: Your specific health goals, age, lifestyle, and response to treatment will determine your optimal injection schedule.
Intensive Protocols: For conditions like addiction recovery or chronic fatigue, more frequent and sustained therapy may be necessary.
Absorption Differences: NAD+ injections offer rapid, convenient absorption compared to oral supplements but differ from the more gradual, sustained benefits of IV infusions.
Mild Side Effects: Common temporary side effects include injection site soreness, nausea, fatigue, or flushing.
Medical Consultation: Always consult a qualified healthcare provider to determine the right protocol and ensure safety.

Nicotinamide Adenine Dinucleotide (NAD+) is a vital coenzyme found in every living cell, crucial for hundreds of metabolic processes, including energy production, DNA repair, and cellular defense mechanisms. As we age, NAD+ levels naturally decline, contributing to decreased cellular function and many age-related health issues. NAD injections offer a way to replenish these levels directly, bypassing the digestive system for more efficient absorption compared to oral supplements. However, determining the correct frequency is a critical step that requires a personalized approach based on your specific health objectives.

The Standard NAD Injection Protocol: Loading and Maintenance

Most clinics and wellness providers follow a two-phase protocol to maximize the effectiveness of NAD+ therapy. This structured approach ensures that your body's NAD+ levels are initially replenished before transitioning to a long-term plan for sustaining them.

The Initial Loading Phase

For those new to NAD injections, a loading phase is often recommended to rapidly build up NAD+ concentrations in the body. This phase typically involves more frequent injections to restore depleted cellular levels and maximize the therapeutic benefits from the start.

Frequency: 1 to 2 times per week
Duration: 4 to 6 weeks

This initial period is designed to provide a foundational boost, particularly for individuals experiencing significant fatigue or other symptoms related to low NAD+ levels.

The Maintenance Phase

After completing the initial loading phase, individuals transition to a maintenance schedule. The goal of this phase is to sustain the benefits achieved and continue supporting overall cellular wellness.

Frequency: Once every 1 to 4 weeks
Duration: Ongoing, as needed, based on individual response and goals

This schedule is more flexible and can be adjusted based on how the individual feels, their lifestyle, and their long-term health objectives.

Customizing Your NAD Injection Frequency

While the loading and maintenance protocol provides a general framework, the ideal frequency for NAD injections is highly dependent on your specific health goals.

General Wellness and Anti-Aging: For those focused on overall health and mitigating the natural aging process, a maintenance schedule of once every 2 to 3 weeks is often sufficient. Some may find monthly injections are enough for ongoing support.
Intensive Recovery (Addiction/Fatigue): In clinical settings, especially for substance withdrawal or chronic fatigue, a more intensive regimen is necessary. This may involve daily injections during the initial detox phase, followed by a tapering to weekly or monthly maintenance. The initial high-dose protocol helps significantly reduce cravings and withdrawal symptoms.
Athletic Performance and Recovery: Athletes and highly active individuals may benefit from a more frequent schedule, such as 1 to 3 times per week during periods of high training or intense recovery.

Understanding the Factors That Influence Your Protocol

Several personal factors, in addition to your health goals, will influence the best injection frequency for you. A medical professional will consider these during a consultation.

Age and Natural NAD+ Decline: As NAD+ levels naturally decrease with age, older individuals may require more frequent injections to achieve and maintain optimal levels.
Lifestyle and Stress Levels: High levels of stress, poor sleep, and a suboptimal diet can deplete NAD+ more quickly, potentially necessitating a more frequent schedule.
Existing Health Conditions: Chronic illnesses can place a higher demand on the body's resources, including NAD+, requiring a more tailored and potentially more intensive treatment plan.
Therapist Recommendations: A reputable healthcare provider will help determine the best dosing schedule based on lab results, health assessments, and individual response to therapy.

Comparison of NAD+ Delivery Methods

NAD+ can be administered in several ways, each with its own frequency, absorption rate, and convenience profile. This comparison table highlights the differences between injections, IV therapy, and oral supplements.


Aspect	NAD+ Injections	NAD+ IV Therapy	Oral NAD+ Supplements
Delivery Method	Administered directly into the muscle (intramuscular) or subcutaneously.	Delivered directly into the bloodstream via an intravenous drip.	Taken by mouth in pill or powder form.
Absorption Rate	Rapid absorption into the bloodstream through muscle tissue.	100% bioavailability, with NAD+ entering the system immediately and steadily.	Poorer absorption due to breakdown in the digestive system.
Typical Frequency	Initial: 1-2x/week for 4-6 weeks; Maintenance: 1-4x/month.	Initial: Daily infusions for several days; Maintenance: Monthly.	Daily use for long-term maintenance.
Convenience	Quick sessions (a few minutes), convenient for regular upkeep.	Longer sessions (1-3 hours), requires more time investment.	Easiest method to incorporate into a daily routine.
Potency	Offers a concentrated, potent dose with good bioavailability.	Highest potency, as it bypasses the digestive system completely.	Less potent due to reduced absorption.

Potential Side Effects and Safety Considerations

While NAD injections are generally safe, understanding the potential side effects is important. Most adverse reactions are mild and temporary, but it is always crucial to receive injections from a qualified professional.

Common side effects may include:

Redness, swelling, or soreness at the injection site.
Temporary fatigue or lethargy.
Nausea or stomach discomfort.
Headaches or mild brain fog.
Flushing or heat sensation.

More serious side effects are rare, but it's important to discuss any health concerns with a medical provider before beginning therapy. High doses or improper administration may increase the risk of side effects. As with any medical treatment, consultation with a healthcare professional is key to a safe and effective plan.

Conclusion: Finding the Right Rhythm for You

NAD injections are a powerful tool for supporting cellular health, energy, and cognitive function. However, the optimal frequency for receiving them is not a universal constant. It is a dynamic process that begins with a loading phase to rapidly elevate depleted NAD+ levels, followed by a personalized maintenance schedule. Your unique health goals, lifestyle, and individual response will ultimately dictate the frequency that is right for you, whether that's for general wellness, intensive recovery, or anti-aging. Working closely with a qualified medical professional is the best way to develop a protocol that is safe, effective, and tailored to your needs. This personalized approach ensures you achieve the maximum benefits of NAD therapy while minimizing potential side effects.
