Does NAD+ IV Therapy Actually Work? What the Evidence Shows

Short answer: no controlled clinical trial has shown that intravenous NAD+ produces a measurable clinical benefit. A 2026 systematic review of 113 intervention studies found zero outcome trials of IV NAD+ itself. Patients often report better energy and focus, but those reports are anecdotal. Trying it is reasonable. Calling it proven is not.

That is a strange thing for a wellness clinic to publish. Most NAD+ pages promise cellular repair, reversed ageing and restored youth. We would rather tell you what the literature actually contains, because the decision you are making is a medical one, and you should make it with real information.

David Patterson, APRN, is a board-certified Advanced Practice Registered Nurse and the founder of AmpUp Wellness in Delray Beach. Every infusion here is reviewed by a licensed clinician before it is given. That includes NAD+ IV therapy in Delray Beach, which we offer with a clear description of what is known and what is not.

What is NAD+ and what does it do in the body?

NAD+, or nicotinamide adenine dinucleotide, is a coenzyme present in every living cell. It carries electrons in the reactions that turn food into usable energy, and it acts as a substrate for enzymes involved in DNA repair and cellular signalling. None of that is controversial. NAD+ was first described in 1906, and its role in cellular metabolism is textbook biochemistry.

The controversy starts at the next step: whether pushing extra NAD+ into a vein changes anything you can feel or measure.

Is there any clinical evidence that NAD+ IV therapy works?

Here is the single most useful number in this article. A PRISMA-guided systematic review published in Ageing Research Reviews (Gallagher and Emmanuel, volume 116, article 103057, 2026) screened the NAD+ supplementation literature and included 113 intervention studies: 33 in humans and 80 in rodents. Its finding on the intravenous route was blunt. No eligible outcomes trials evaluated intravenous or intramuscular NAD+ itself for anti-ageing or wellness indications.

Not "weak evidence." Not "mixed results." Zero controlled outcome trials of the thing being sold. Most of the human data that does exist studied oral precursors such as nicotinamide riboside and nicotinamide mononucleotide, which are different molecules taken by a different route.

This does not mean IV NAD+ does nothing. It means nobody has run the study that would tell us either way.

Does NAD+ actually decline as you get older?

This is the claim almost every NAD+ marketing page rests on, and it is shakier than you would expect. A study published in Nature Metabolism on 14 May 2026 by Tretowicz and colleagues measured whole-blood NAD+ across seven independent human cohorts and found that levels remained stable with age, with no significant correlation to chronological age. The same assay did detect the expected rise after nicotinamide riboside supplementation, so the method was working.

There is still an open scientific question about NAD+ in specific tissues, which blood does not necessarily reflect. But the simple story, that your NAD+ tank empties as you age and an IV refills it, is not supported by the best available human blood data.

Is NAD+ IV therapy safe?

Safety here depends far more on the pharmacy than on the molecule. On 30 October 2024, the FDA issued a communication reminding compounders to use ingredients suitable for sterile compounding. It named NAD+ directly, reporting that compounders were using food-grade nicotinamide adenine dinucleotide to make injectable products, and that patients had experienced severe chills, shaking, vomiting and fatigue, some requiring medical treatment. The FDA described those reactions as consistent with excessive endotoxin levels.

Then it happened. A compounded NAD+ for Injection product was voluntarily recalled on 30 July 2025, and the FDA classified that recall as Class I on 21 October 2025, its most serious category, reserved for products that may cause serious harm or death. Testing of an unopened vial from the recalled lot found bacterial endotoxins at 3,360 EU/mL, and three patients developed low blood pressure, uncontrollable shaking and body aches shortly after administration.

That is not a theoretical risk. Contamination in compounded NAD+ has already sent real patients to medical attention. The lesson is not that NAD+ infusions are inherently dangerous. It is that where your NAD+ comes from, and how it is compounded and tested, is the thing that matters, and most patients never think to ask.

How do you tell a good NAD+ provider from a bad one?

Use this as a checklist. Ask these five questions before you sit in the chair, at any clinic, including ours.

What to check	Green flag	Red flag
NAD+ source	Sourced from a licensed compounding pharmacy or 503B outsourcing facility, pharmaceutical grade, with documentation available on request	Cannot name the pharmacy, or uses ingredients labelled for food or dietary supplement use
Sterile compounding	Finished-product endotoxin and sterility testing performed before release	No testing documentation, or product mixed on site without sterile facilities
Dose transparency	Tells you the exact milligram dose, the infusion volume and the drip duration before you book	Vague language such as "our signature blend" with no dose given
Medical supervision	Licensed clinician reviews your history, medications and suitability; someone qualified is present throughout	No intake review, or no licensed clinician on site during the infusion
Claims made	Describes what is known, what is unproven, and what side effects to expect	Promises reversed ageing, disease treatment or guaranteed results

What does an NAD+ infusion actually feel like?

NAD+ is infused slowly, and slow matters. Run too fast, it commonly causes chest tightness, flushing, nausea, cramping and a feeling of pressure in the head. Those sensations usually ease within a minute or two when the drip rate is reduced, which is why a clinician should be adjusting the rate rather than leaving you on a fixed setting. Sessions typically run between one and four hours depending on dose. Plan your day around it.

If your interest is really in feeling better hydrated and less depleted, a standard IV hydration and vitamin therapy session is faster, cheaper and better characterised. We cover the practical side of that in our guide to IV therapy in Delray Beach.

Who should not get NAD+ IV therapy?

Because the evidence base is thin, the threshold for caution should be higher, not lower. NAD+ infusions are not appropriate during pregnancy or breastfeeding. Anyone with significant cardiac, renal or hepatic disease, an active infection, or a complex medication list needs a clinician to review suitability first. If you are looking for treatment of a diagnosed medical condition, an unproven infusion is not the right tool, and we will tell you so.

Frequently asked questions

How many NAD+ IV sessions do you need to notice anything?

There is no evidence-based answer, because no controlled trial has established a dosing schedule for IV NAD+. Providers commonly suggest a series, but that convention comes from practice patterns, not published protocols. Be sceptical of anyone who quotes you a precise number.

Is NAD+ IV therapy FDA approved?

No. NAD+ for injection is a compounded preparation, not an FDA-approved drug, and compounded drugs are not reviewed by the FDA for safety or effectiveness before marketing. That is exactly why pharmacy sourcing and testing matter so much.

Is oral NAD+ or NMN as good as an IV?

Oral precursors such as nicotinamide riboside and nicotinamide mononucleotide have far more human trial data behind them than IV NAD+ does, including randomised studies. Whether that translates into benefits you can feel is a separate and still unsettled question.

Does NAD+ IV therapy help with hangovers or jet lag?

No controlled trial supports this. Any improvement you notice after an infusion may well come from the fluid volume and rest, which is a reasonable thing to want, and an honest reason to choose a simpler hydration drip instead.

What is the difference between NAD+ and peptide therapy?

They are different categories of treatment with separate evidence bases, and the quality of that evidence varies by individual peptide. We discuss candidacy and what is known in our overview of peptide therapy.

Should you try NAD+ IV therapy in Delray Beach?

If you want a guarantee, the honest answer is that nobody can give you one. If you understand that the clinical evidence is absent rather than negative, that the risk is manageable when the product is properly sourced and the drip is properly supervised, and that you are choosing to try something unproven with clear eyes, that is a legitimate decision to make.

That is the standard we hold ourselves to. If you want to talk through whether NAD+ IV therapy at our Delray Beach clinic makes sense for you, David Patterson, APRN, will review your history and give you a straight answer, including if that answer is no.
