NAD+ drips are sold at wellness clinics for hundreds of dollars a session. NMN capsules cost a fraction of that. We compared what each actually does, what it costs and what can go wrong.
Neither NMN nor NAD+ IV therapy is proven to slow aging. Oral NMN has a handful of small, short placebo-controlled trials showing it raises blood NAD+ and is well tolerated, at roughly $1.60 to $2.30 a day for the brand we priced. NAD+ IV drips cost about $400 to $1,000 per session, have no controlled anti-aging trials, often cause nausea or chest tightness during infusion, and use compounded products that are not FDA-approved.
NAD+ is a coenzyme found in every cell, involved in turning food into energy and in DNA repair. Levels in some tissues appear to fall with age in animal studies, which is why "NAD+ boosting" has become a longevity trend. Our complete guide to NAD+ explains the biology in more detail.
There are two main approaches. You can take a precursor such as NMN (nicotinamide mononucleotide) by mouth and let your body build NAD+ from it, or you can have NAD+ itself dripped into a vein at a clinic. For background on the oral route, see our complete guide to NMN as an NAD+ precursor.
| Oral NMN | NAD+ IV therapy | |
|---|---|---|
| Typical cost | About $49 to $69 a month for 500 mg a day (one brand, October 2026) | About $400 to $1,000 per session (clinic prices, 2026) |
| Time | Seconds a day | Often several hours per drip, depending on dose |
| Human evidence | Several small placebo-controlled trials, 4 to 12 weeks | Pilot studies only; no controlled anti-aging trials |
| Raises blood NAD+? | Yes, in multiple trials | Yes, temporarily, in a small pilot study |
| Common side effects | Few reported in trials; possible mild stomach upset | Nausea, flushing, abdominal discomfort, headache, chest tightness during infusion |
| Regulatory status | Sold as a dietary supplement (FDA reversed its ban in September 2025) | Compounded drug; no FDA-approved NAD+ IV product |
Prices vary a lot by city, dose and whether a nurse comes to your home. A cost roundup on HealingMaps, with prices checked in August 2026, listed Drip Hydration at $799 for a 500 mg NAD+ IV and quoted typical ranges of $429 to $879 in clinic and $628 to $1,078 for mobile visits from a California provider. An Arizona clinic, AZ IV Medics, listed NAD+ from $80 for 100 mg up to $690 for 1,000 mg, plus the cost of fluids, when we checked in October 2026.
Clinics usually recommend a "loading" series of several drips followed by top-ups. Even at the low end, a few sessions can cost more than a year of oral NMN.
For comparison, one NMN brand we checked, GenuinePurity, charged $49 a month on subscription or $69 for a single bottle of 500 mg-a-day capsules in October 2026, roughly $1.60 to $2.30 a day. Heads-up: the $19 first-bottle offer auto-renews at $49 every 30 days until you cancel. Other brands vary.
The best-known human study of IV NAD+ is a 2019 pilot by Grant and colleagues in Frontiers in Aging Neuroscience. Eight healthy men aged 30 to 55 received 750 mg of NAD+ over six hours, and three received saline. Plasma NAD+ did not rise at all in the first two hours, then climbed to about four times baseline by the end of the six-hour infusion. It was a metabolism study, not a test of any health benefit.
Funding is worth noting. The study was co-funded by NAD+ Research Inc., run at a wellness center that sells IV NAD+, and one author directed both. A July 2026 review on Science-Based Medicine cited a February 2026 systematic review of 113 studies that found no eligible controlled trials of IV, intramuscular or injected NAD+ for anti-aging or wellness. In plain terms, nobody has shown that drips make healthy people age better, think more clearly or feel more energetic compared with a placebo.
NMN has more human data, though it is still modest. A 2023 review in Advances in Nutrition covered trials in which people took 250 to 1,250 mg a day for up to 12 weeks. NMN consistently raised blood NAD+, and some small trials reported changes in muscle insulin sensitivity, walking distance or muscle performance. Results were mixed, groups were small and several trials were funded by NMN makers. The review judged oral NMN safe and well tolerated in the short term.
So the honest comparison is "a little evidence" versus "almost none." Neither has shown a meaningful anti-aging effect in people.
Clinics themselves list side effects during infusion, including nausea, flushing, abdominal discomfort or pressure, headache, fatigue and chest tightness, especially if the drip runs too fast. This is a big part of why sessions take hours. Any IV also carries the usual risks of bruising, vein irritation and infection at the needle site.
Product quality is a real concern. In October 2024 the FDA warned that some compounders were using food-grade NAD+, meant for oral products, to make IV drugs. The agency received reports of severe chills, shaking, vomiting and fatigue after NAD+ injections, some needing medical treatment, which it said were consistent with excessive endotoxins (bacterial toxins). In 2025 the FDA classified a recall of NAD+ for injection from GenoGenix LLC as Class I, its most serious level, because of elevated endotoxin levels.
In published trials, adverse events on NMN were no more common than on placebo at doses up to 2,000 mg a day for four weeks. Long-term safety is unknown, and product purity varies between brands. People who are pregnant, have cancer, or take diabetes or blood pressure medicines should talk to their doctor first. Our article on NMN side effects covers who should avoid it.
No NAD+ IV product is FDA-approved, and NAD+ drips are not approved to treat aging or any other condition. Clinics use products made by compounding pharmacies, which are not reviewed by the FDA for safety or effectiveness the way approved drugs are.
Oral NMN is a dietary supplement. The FDA said in late 2022 that NMN could not be sold as a supplement, then reversed that position on September 29, 2025, after a petition and lawsuit by the Natural Products Association. Supplements are not approved for any health use either, but NMN can now be legally sold. If you are deciding between NMN and nicotinamide riboside, our GenuinePurity NMN vs Tru Niagen comparison looks at both.
If you want to experiment with raising NAD+, oral NMN is far cheaper, easier and better studied than an IV drip, though its real-world benefits are still unproven. NAD+ IV therapy costs hundreds of dollars per session, has no controlled evidence for anti-aging, commonly causes uncomfortable side effects during infusion and has had contamination problems serious enough for FDA warnings and a Class I recall.
If you still want to try a drip, ask the clinic where its NAD+ comes from, whether it is made by an FDA-registered 503B outsourcing facility and who supervises the infusion. Tell your doctor first if you have heart disease, are pregnant or take regular medication.
