NAD+ therapy has become the headline act of longevity marketing. Clinics promise cellular repair, sharper thinking, steadier energy, and a slower clock.
The molecule is real and the interest is understandable. The evidence sits at a much earlier stage than the advertising suggests.
SDBody offers NAD+ infusions under supervision at its La Jolla clinic and tells patients where the research actually stands before they book. Here is that picture, without the sales gloss.
Quick Summary
- NAD+ is a coenzyme involved in how cells make energy, and levels decline with age.
- NAD+ infusions are not FDA approved to treat or prevent any medical condition.
- A 2026 systematic review found no outcome trials testing intravenous NAD+ for aging or wellness results.
- Infusions run slowly, because a faster rate commonly brings chest tightness, nausea, flushing, and cramping.
- Kidney disease, heart failure, fluid overload, bleeding disorders, pregnancy, and some medications need a clinician’s review first.
What NAD+ is, and why everyone is talking about it
NAD+, short for nicotinamide adenine dinucleotide, is a coenzyme involved in cellular energy metabolism. Levels fall as people age, which is what drives the interest in raising them, whether through oral precursors or an infusion.
That much is settled biology. The leap happens when a clinic turns a coenzyme into a promise.
What the evidence actually shows
A systematic review published in 2026 pulled together 113 intervention studies, 33 of them in humans. Oral precursors reliably raised NAD-related markers in the blood and were generally well tolerated over weeks to months, while effects on function, metabolism, and other health outcomes came out mixed and often absent.
For infusions specifically, that review found no eligible outcome trials testing intravenous NAD+ for aging or wellness results, and concluded that clinical effectiveness for those goals remains inconclusive.
Even the basics are still being mapped. A pilot study that infused NAD+ over six hours found no rise in plasma NAD+ or its metabolites for the first two hours, which suggests the body cleared it about as fast as it arrived.
It is the same pattern described in what hyperbaric oxygen therapy can and cannot do: a real mechanism, and outcome research that has not caught up with the marketing.
What NAD+ therapy cannot promise
If a clinic tells you an infusion will undo aging, repair your DNA, or fix a diagnosed condition, that is a marketing claim rather than a clinical one. No infusion has been shown to do those things.
SDBody offers NAD+ as a supervised wellness service rather than a treatment. Patients ask for it, it can be given safely under supervision, and the clinic says exactly that before anyone books.
What an NAD+ infusion feels like
Most of the discomfort people describe comes down to speed. A fast drip is commonly associated with chest tightness, nausea, flushing, and cramping, and slowing the rate generally settles it. That is why an NAD+ session runs considerably longer than a standard vitamin drip.
Tell the nurse the moment you feel it, because that feedback is what the rate adjustment is for. Staff stay with you through the session and adjust to your tolerance.
Who should not book an NAD+ infusion
An infusion is a medical procedure, so screening matters more than the ingredient list. Talk to a clinician first with kidney disease, heart failure, a history of fluid overload, a bleeding disorder, during pregnancy or breastfeeding, or while taking medications that interact with high-dose vitamins.
The same caution applies when the real question is why energy has been low for months. That belongs to bloodwork, and panels are drawn on site, so diagnostic labs in La Jolla is the better place to start.
How to judge an NAD+ offer anywhere
- What dose is in the bag, and over how long will it run?
- Who monitors the infusion, and what happens if symptoms start?
- What does the clinic claim it does, and what evidence sits behind that claim?
- What would show it is working, and at what point would you stop?
A clinic that answers those plainly is a different proposition from one selling a longer menu. The service page for IV and NAD+ therapy in La Jolla sets out what a clinician reviews before a first infusion.
Frequently asked questions about NAD+ therapy
Does NAD+ therapy really work?
For aging and general wellness goals, the honest answer is that it has not been shown. A 2026 systematic review found no outcome trials testing intravenous NAD+ for those goals and called clinical effectiveness inconclusive.
Is NAD+ therapy FDA approved?
No. NAD+ infusions are not FDA approved to treat or prevent any medical condition, which is worth knowing before a clinic quotes you a package price.
Why does an NAD+ drip cause chest tightness?
That sensation is commonly linked to the infusion running too quickly. Slowing the rate generally settles it, so tell the nurse the moment it starts.
How long does an NAD+ infusion take?
Longer than a standard vitamin drip, because the rate has to stay slow for comfort. The team confirms the expected time for your infusion when you book.
Who should not have an NAD+ infusion?
Anyone with kidney disease, heart failure, a history of fluid overload, or a bleeding disorder, anyone pregnant or breastfeeding, and anyone taking medications that interact with high-dose vitamins should be reviewed by a clinician first.
Is NAD+ therapy available at both SDBody clinics?
Yes. IV and NAD+ therapy run at the La Jolla clinic on Fay Ave and at the Mission Hills clinic.
Talk through NAD+ therapy with the SDBody La Jolla team
If NAD+ is on your list, the useful first step is a conversation about what it can and cannot do for your goals. The clinical team reviews your health history, explains where the research stands, and says plainly when an infusion is the wrong answer.
