Introduction: NAD+ Therapy and the 2025 Hype Cycle
Once a niche wellness treatment, NAD+ IV therapy has become a multimillion-dollar industry promising energy, anti-aging, and brain optimization. From celebrity endorsements to boutique IV lounges, NAD+ drips are now marketed as panaceas for fatigue, addiction, and longevity. But in 2025, as regulators scrutinize these claims, clinicians and patients must ask: What’s real, what’s risky, and where does NAD+ therapy actually fit?
This evidence-based review separates data from marketing, outlining legitimate use cases, limitations, and safer, physiologic alternatives. For providers offering infusion or functional wellness services, understanding the science, consent language, and ethical positioning of NAD+ is essential.

What Is NAD+ and Why It Matters
Summary: NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme for cellular metabolism, mitochondrial function, and DNA repair.
NAD+ exists in every cell, driving redox reactions that produce ATP and regulate aging-related pathways such as sirtuins and PARPs. Levels naturally decline with age, stress, and poor sleep, correlating with fatigue, neurodegeneration, and metabolic dysfunction (Yoshino et al., 2021).
This biologic importance has led to interest in therapies claiming to boost NAD+ levels—including oral precursors (nicotinamide riboside, NMN), injections, and IV infusions.
How NAD+ IV Therapy Works (and What’s Claimed)
Summary: NAD+ drips deliver the coenzyme directly into the bloodstream, bypassing intestinal metabolism—but claims often exceed evidence.
IV formulations typically contain 250–750 mg of NAD+ administered over 60–120 minutes. Clinics market them for:
-
Fatigue and brain fog relief
-
Addiction recovery and detox support
-
Anti-aging and mitochondrial repair
-
Improved metabolism and athletic performance
While IV delivery ensures 100% bioavailability, most data supporting these effects are anecdotal or extrapolated from small animal and pilot human studies.
Evidence Review: What the Science Shows
Summary: Human evidence for NAD+ IV therapy remains limited; benefits are modest and short-term.
1. Energy and Fatigue
A 2023 systematic review ( Nutrients) found insufficient evidence that IV NAD+ improves fatigue or energy in healthy adults. Most studies rely on subjective self-reports without controlled design.
2. Addiction and Withdrawal
Some older studies (circa 1960–1980s) suggested NAD+ may aid detoxification, but modern randomized trials are lacking. A 2022 JAMA Psychiatry commentary noted that claims of addiction recovery are unsupported by current clinical data.
3. Neuroprotection and Aging
Animal data show NAD+ precursors can improve mitochondrial resilience and cognitive function. However, these results come primarily from oral NMN or NR supplementation, not IV NAD+ (Yoshino et al., 2021).
4. Metabolic Health
Small human trials indicate potential benefits for insulin sensitivity when NAD+ is increased via precursors—but again, IV NAD+ evidence is minimal and lacks metabolic biomarker endpoints.
In short: while NAD+ biology is real and promising, IV infusion efficacy is not yet validated in controlled human research.
Risks, Side Effects, and Safety Profile
Summary: Though often promoted as “natural,” NAD+ IV therapy can pose risks if improperly administered or misrepresented.
Common Reactions
-
Flushing, chest tightness, or nausea (related to infusion rate)
-
Vein irritation or phlebitis
-
Headache or dizziness
Rare but Serious Risks
-
Infection or infiltration from IV access
-
Electrolyte imbalance when combined with other drips
-
Contamination or instability from compounded NAD+ formulations
Since NAD+ is not an FDA-approved drug for these indications, most infusions use compounded preparations that vary in sterility and stability. Clinics must follow USP <797> sterile compounding standards and obtain informed consent specifying off-label use.
Regulatory and Ethical Considerations
Summary: NAD+ IV therapy occupies a regulatory gray zone.
The U.S. Food and Drug Administration (FDA) does not recognize NAD+ infusions as approved treatments for fatigue, aging, or detox. Marketing such claims may violate FTC advertising regulations (FDA, 2024).
Providers should:
-
Avoid disease claims (e.g., “treats Alzheimer’s” or “reverses aging”).
-
Use consent forms disclosing unapproved status and potential risks.
-
Keep records of compounding sources and sterility documentation.
Clinicians can align practice with functional medicine principles that emphasize evidence-based lifestyle and nutritional interventions over unproven infusions. Functional Medicine Basics offers foundational training in integrative, compliant patient care.
Natural Alternatives to Boost NAD+
Summary: Lifestyle and nutrition remain the most reliable, low-risk ways to support NAD+ metabolism.
1. Sleep and Circadian Health
NAD+ synthesis follows circadian rhythms. Restorative sleep enhances sirtuin activation and mitochondrial repair. Sleep deprivation rapidly depletes NAD+ precursors.
2. Exercise
High-intensity interval and resistance training stimulate NAMPT, the rate-limiting enzyme in NAD+ salvage pathways. Regular training increases NAD+ turnover naturally.
3. Diet
Diets rich in tryptophan, niacin, and polyphenols (e.g., turkey, salmon, berries) supply NAD+ precursors. Intermittent fasting and calorie restriction also enhance NAD+ recycling via AMPK activation.
4. Oral Supplements
Precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) have better safety data and oral bioavailability than IV NAD+. Both remain under investigation for long-term outcomes.
Clinical Integration: When (and If) to Consider NAD+ IV
Summary: NAD+ infusions may serve as adjuncts in select, closely monitored patients—but not first-line therapy.
Appropriate use cases:
-
Short-term adjunct for chronic fatigue or withdrawal under medical supervision
-
Post-viral or post-surgical recovery with metabolic monitoring
-
Research contexts evaluating mitochondrial biomarkers
Not recommended for:
-
Routine wellness or anti-aging claims
-
Cognitive enhancement without medical indication
-
Long-term self-administration outside clinical oversight
When offered, NAD+ therapy should be paired with informed consent, metabolic evaluation, and concurrent lifestyle optimization.
The Bottom Line
NAD+ is vital for life—but IV infusions promising to restore it are running ahead of science. While short-term use appears low-risk under sterile, supervised conditions, there is no high-level evidence that NAD+ drips improve energy, longevity, or metabolism in healthy adults.
Clinicians can responsibly guide patients by combining transparent education, consent-driven care, and proven strategies like sleep, nutrition, and exercise. The future of NAD+ therapy will depend on rigorous research, not marketing momentum.

No clinical trials confirm anti-aging outcomes in humans.
Sleep, exercise, nutrient-rich diets, and oral precursors have proven physiologic benefits.
