Short answer: what is NAD+ IV therapy? It is a drip that delivers NAD+, a molecule found in every cell of your body, directly into a vein, usually slowly over a few hours. It is popular in wellness and “longevity” circles, but research in humans is still at an early stage, and there is no good evidence yet that a NAD+ drip slows ageing or reliably boosts energy in healthy people.
This guide explains NAD+ in plain English: what it does in the body, why people are interested, what the studies actually show, what to expect from a drip, and who should avoid one. It is general education, not a recommendation, so you can make up your own mind with realistic expectations.
What is NAD+?
NAD+ stands for nicotinamide adenine dinucleotide. It is a coenzyme, a helper molecule that many of the body’s enzymes need in order to work. Its best-known job is helping your cells turn the food you eat into usable energy. It is also involved in processes that repair everyday wear and tear inside cells.
Your body makes its own NAD+, partly from forms of vitamin B3 in your diet. Some supplements contain “precursors”, building blocks the body can turn into NAD+, such as nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN). A NAD+ drip skips that step and puts NAD+ itself into the bloodstream.
Why are people interested in NAD+ IV therapy?
Because NAD+ is so central to how cells produce energy, scientists have asked whether levels fall as we age, and whether topping them up might support healthier ageing. Studies in animals have looked promising, and that research has fuelled a large wellness market for NAD+ supplements and drips. Clinics and influencers often describe NAD+ drips as a way to feel sharper, more energetic or “younger at a cellular level”.
Those claims run well ahead of the evidence. Results in mice don’t always carry over to people, and most human research so far has looked at oral precursors rather than drips.
NAD drip benefits: what the research shows so far
A 2025 review in the journal Nature Metabolism, NAD+ precursor supplementation in human ageing: clinical evidence and challenges (Vinten and colleagues), looked at the human evidence. The authors reported that:
- evidence that NAD+ levels fall with age in humans has been consistently seen in only a limited number of studies
- although animal studies support the idea, human clinical trials of NAD+ precursors have shown limited efficacy
- data on how NAD+ behaves in different human tissues remains sparse, and more clinical studies are needed
Research on NAD+ given directly into a vein is even more limited. One of the few published human studies is a small pilot by Grant and colleagues (2019) in Frontiers in Aging Neuroscience. Eleven healthy men took part: eight received NAD+ by drip over six hours, and three received a salt-water drip for comparison. The researchers tracked NAD+ and related substances in blood and urine. Surprisingly, NAD+ levels in the blood didn’t rise at all for the first two hours, suggesting the body takes it up or breaks it down quickly. No adverse events were seen in this small group.
That study measured what happens to NAD+ in the body. It wasn’t designed to test whether people felt more energetic, thought more clearly or aged more slowly. So, in plain terms:
- NAD+ is a genuinely important molecule and an active area of research
- it has not been shown that NAD+ drips slow ageing, extend life or reliably improve energy
- some people say they feel clearer or more energetic afterwards, but personal experience isn’t proof
How long does a NAD drip take?
Longer than most drips. NAD+ is usually given slowly, because many people feel uncomfortable when it runs quickly. Depending on the dose and how you feel, a drip can take a couple of hours or more. In the research study above, the infusion lasted six hours. Any provider should tell you in advance how long to set aside, and you should plan a quiet afternoon rather than squeezing it in before a flight or a dive.
What it feels like and possible side effects
Sensations commonly reported during NAD+ drips include:
- flushing or a feeling of warmth
- nausea or stomach cramps
- a tight or heavy feeling in the chest
- headache, light-headedness or tiredness
These are often linked to the speed of the drip, and slowing it down usually helps. Tell the nurse or doctor at once if you feel any of them. As with any drip, there is also a small risk of bruising, vein irritation, fainting and, rarely, infection or an allergic reaction. Because there is far less research on NAD+ than on simple hydration drips, it is sensible to be more cautious, not less.
NAD+ drip or supplements?
Oral precursors such as NR and NMN are cheaper, don’t need a needle and have been studied more in humans than drips, although, as the 2025 review notes, the benefits seen so far have been limited. A drip delivers NAD+ directly, but no study has shown that this leads to better health outcomes than supplements, or than a balanced diet, regular exercise and good sleep. Whichever route you consider, talk to your doctor first if you have a medical condition or take regular medication.
Who shouldn’t have a NAD+ drip
Avoid a NAD+ drip, or get advice from your own doctor first, if you:
- are pregnant or breastfeeding
- have a heart condition, high blood pressure, or kidney or liver disease
- have, or have had, cancer, as the effects of raising NAD+ in this situation are not well understood
- take regular medication
- are feeling unwell, have a fever or are dehydrated from illness
A proper health screening before any drip should cover all of these. If a provider doesn’t ask, that is a warning sign.
When to see a doctor
Call 1669 or go to hospital straight away if, during or after a drip, you have chest pain that doesn’t ease when the drip is stopped, difficulty breathing, swelling of the face, lips or tongue, a racing or irregular heartbeat, or you faint. See a doctor if the drip site becomes red, hot, swollen or painful, or if you have a fever afterwards. If you are drawn to NAD+ because of ongoing tiredness, low mood or poor concentration, see a doctor about those symptoms first, as they can have causes that need proper treatment.
FAQs
What are the main NAD drip benefits?
The claimed benefits are more energy, clearer thinking and healthier ageing. None of these has been reliably shown in human studies of NAD+ drips yet. You may feel rested and hydrated afterwards, partly thanks to the fluid and a few quiet hours.
Is NAD+ IV therapy safe?
Small studies have not reported serious problems, but the research is limited and uncomfortable side effects are common if the drip runs fast. It should only be given after a health screening, by a registered nurse or doctor who stays with you throughout.
How often do people have NAD+ drips?
There is no evidence-based schedule. Providers suggest very different plans, which is itself a sign that the science isn’t settled. Be cautious about expensive packages of many sessions.
Can I have a NAD+ drip before a dive or a flight?
It is better not to schedule one right before. The drip is long, side effects such as nausea or light-headedness can linger for a while, and it is wise to rest afterwards.
