If you've spent any time in the wellness internet in the last two years, you've probably heard about NAD+ IV therapy. It shows up in longevity podcasts, celebrity health routines, and clinic menus next to vitamin drips. The marketing claims are aggressive: more energy, mental clarity, slower aging, better workouts, faster recovery.
Some of that may turn out to be true. A lot of it is ahead of the evidence.
Here's what we know, what we don't, and what we'd tell a friend before they book a session.
What NAD+ actually is
NAD+ stands for nicotinamide adenine dinucleotide. It's a coenzyme that exists in every cell in your body and [plays a role in hundreds of biological processes](https://www.peachiv.com/blog-post/nad-iv-therapy-safety-side-effects), including converting food into energy, DNA repair, and how cells respond to stress.
NAD+ levels naturally decline with age. This is well-established biology, not a marketing claim. The question that's driving the current interest is whether replenishing NAD+ through IV infusions produces the outcomes people hope for. That's where the science gets thinner.
What the IV therapy involves
An NAD+ IV session typically runs two to four hours. Sterile NAD+ is dissolved in saline and infused slowly into a vein, usually in the arm. The slow pace isn't optional. Fast infusions are associated with more side effects.
Most clinics recommend a series of sessions to start, often [four to ten over several weeks](https://www.trimbodymd.com/faqs/nad-iv-therapy-benefits-and-side-effects/), followed by occasional maintenance sessions. Pricing varies significantly by city and clinic, but expect it to be one of the more expensive treatments in any wellness menu.
What the evidence actually supports
Here we need to be careful.
NAD+ IV therapy is [not FDA-approved for any specific medical condition](https://www.peachiv.com/blog-post/nad-iv-therapy-safety-side-effects). It's classified as a dietary supplement, which means clinics can offer it but can't legally make clinical claims about what it treats. Most of the published research is preliminary, involves small sample sizes, or comes from animal studies.
What that means in plain language:
- The biology of NAD+ is real and well-understood - The claims about what NAD+ IV therapy does for energy, aging, cognition, and recovery are largely based on early research and clinical observation, not large human trials - The field is active and more evidence is coming, but we're not there yet
If a clinic or provider promises specific outcomes, that's a signal to slow down, not speed up. The honest answer right now is "some people report benefits, the mechanism is plausible, the evidence is still developing."
What a session actually feels like
Most people are surprised by how physical the experience is.
The infusion has to be administered slowly because faster rates tend to trigger side effects. The [most common ones](https://merciehealth.com/services/nad-katy-texas/) are flushing, chest tightness, shortness of breath, nausea, cramping, and headache. These usually resolve when the infusion rate is slowed down. Good clinics will adjust in real time.
After a session, people describe a range of experiences. Some feel immediate energy. Others feel drained for a day and then notice something shift. Some feel nothing specific at all. The variation is wide, and the placebo effect in high-priced wellness treatments is meaningful.
Before you book
This is one of the treatments where the venue matters more than usual. A few things we'd check:
- **Is a licensed medical professional on site?** NAD+ is administered intravenously. This is not a spa service. Whoever is inserting the IV should be a nurse or doctor, and a physician should be overseeing the protocol. - **Is there a consultation before the first session?** A good clinic will screen for contraindications, review your medications and medical history, and adjust the protocol to your specific situation. - **What's their protocol if you have a reaction?** They should be able to tell you without hesitation. - **Are they making specific medical claims?** A clinic that promises to cure depression, reverse aging, or treat a specific condition is overreaching. Credible providers are more measured.
Talk to your doctor before booking your first session, especially if you're on any medications, have any underlying health conditions, or are pregnant.
Who it might not be right for
NAD+ IV therapy [is not recommended](https://driphydration.com/what-is-nad-iv/) for people with certain cardiovascular conditions, kidney problems, during pregnancy or breastfeeding, or for anyone with an active infection. This isn't an exhaustive list. The clinic should screen you properly.
If you have any concerns, the answer isn't to skip the screening and hope. The answer is to ask a doctor.
How to think about cost
NAD+ IV therapy is expensive. Single sessions often run several hundred dollars, and recommended protocols of multiple sessions can add up quickly. It's worth being honest with yourself about what you're actually buying.
If you're curious, healthy, and have the budget, one or two sessions will tell you whether it resonates. If you're managing a specific health concern, the honest move is to start with your doctor, not an IV drip.
