How do I check a clinic that offers NAD+ injections or IV therapy?

This is a checklist for checking a clinic, drawn from regulator and legal sources. It does not say that any clinic is safe or unsafe, and it is not advice.

How can I check a clinic is registered?

Ask the clinic for its registered provider name and location ID, then look it up on the regulator’s own register for the part of the UK where it operates.

The regulator depends on where the clinic is.

Where	Regulator	How to check	Worth knowing
England	Care Quality Commission (CQC)	Search its find care services page by service name or location 4	Registration covers set regulated activities, not every service 1
Wales	Healthcare Inspectorate Wales (HIW)	Ask the clinic for its HIW registration details and check with HIW 6	A nurse-led clinic may not need to register 5
Scotland	Healthcare Improvement Scotland (HIS)	Search its independent healthcare provider page by name, location or keyword 8	Registration turns on the professional providing the service 7

We have not researched the register for Northern Ireland.

What does registration show, and what does it not show?

It shows that a location is on a regulator’s register. It does not show that the regulator has assessed NAD+ itself.

The CQC says its regulated activity “Treatment of disease, disorder or injury” does not include “Interventions carried out purely for cosmetic purposes” or alternative and complementary medicine, with an exception for osteopathy and chiropractic. ¹

In a 2018 inspection summary the CQC found that the intravenous and intramuscular vitamin services at one clinic were “out of CQC scope of registration and regulation”. ²

We found no CQC page specifically about NAD+, so we cannot say how it would treat an NAD+ service. ²

Our own check shows why a name search may not be enough. We matched our 92 listed clinics against the CQC’s open data of 2 November 2026. ³

Result of our check	Clinics
Matched a registered location	41
Matched a registered provider but not the clinic’s own address	5
Not found	45
Could not be checked (Wales)	1

Some clinics are registered under a different name from their trading name, and “not found” does not prove a clinic is unregistered. ³

Of the 92, 29 mention the CQC on their own websites, and 20 of those say explicitly that they are registered or regulated. A statement on a clinic’s site is not the same as an entry on the register.

For the legal background, see how NAD+ is regulated.

Who gives the injection or drip, and what registration might they hold?

If the product is a prescription-only medicine, it must be prescribed by an appropriate practitioner and given by one, or by someone acting on their directions. ¹¹

Appropriate practitioners include doctors, dentists, supplementary prescribers, nurse independent prescribers and pharmacist independent prescribers. ¹¹

The person who prescribes and the person who gives the injection may be different people, so it is worth asking about both.

Profession	Regulator	What you can check
Doctor	General Medical Council (GMC)	That the doctor is on the GMC’s register
Nurse or midwife	Nursing and Midwifery Council (NMC)	The NMC’s register shows who can practise in the UK, searchable by PIN or name 9
Pharmacist	General Pharmaceutical Council (GPhC)	That the pharmacist is on the GPhC’s register

The NMC says a Patient Specific Direction is the legal method of prescribing, including when a prescriber delegates the administration of a prescription-only medicine. ¹⁰

It also says prescribers must have enough knowledge of your health and your full medical and prescribing history before supplying medicines. ¹⁰

Whether NAD+ is a prescription-only medicine is not settled in any public MHRA statement we could find. The legal status guide explains what is and is not known.

What questions could I ask a clinic?

These 12 questions come from the rules and studies in our evidence review, and each one lists why it matters.

#	Question you could ask	Why it matters
1	Who is the prescriber, what is their professional registration (GMC, NMC or GPhC), and have they assessed my medical history before I am treated?	Prescription-only medicines may be supplied only on a prescription from an appropriate practitioner, and prescribers need your full medical and prescribing history. 10, 11
2	Is there a patient-specific prescription or direction for me, rather than a stock supply?	The NMC says a Patient Specific Direction is the legal method of prescribing, including when administration is delegated. 10
3	Who will insert the cannula or give the injection, and what is their registration?	Giving a prescription-only medicine by injection is lawful only by an appropriate practitioner or someone following their directions. 11
4	Is the clinic registered with the CQC, HIW or HIS, and what are the registered provider name and location ID, so I can check the register myself?	Registration is regulator-specific, and trading names can differ from registered names. 1, 3
5	Does the registration cover this service, and which regulated activities does it list?	Scope turns on whether a service treats a disease, disorder or injury, and the CQC has found IV and IM wellbeing-only services outside it. 1, 2
6	What exactly is the product (a licensed medicine, an unlicensed special or an imported product), who supplies it, and what is the batch and expiry?	Unlicensed supply is allowed only for an individual patient’s clinical need, not for cost or convenience, and such products may not have been assessed for safety, quality and efficacy. 12, 13
7	What evidence do you rely on for any benefit you describe, and are those human trials of NAD+ injections specifically?	A 2026 systematic review found no outcomes trials of IV or intramuscular NAD+ for ageing-related or wellness uses, and the CAP Code requires objective claims to be backed by evidence. 14, 20
8	How fast will the infusion run, how long will it take, who monitors me, and what happens if I feel flushing, nausea, cramps, chest pressure or a racing heart?	These effects are reported with IV NAD+, particularly at faster infusion rates, in small studies with no incidence data. 16, 17
9	What infection-prevention steps do you follow, and which signs at the needle site (redness, swelling, pain) should make me contact you?	An NHS trust leaflet says a cannula can lead to infections and that phlebitis is the most common complication, while the NHS says bruising or swelling after a blood test should go away after a few days. 18, 19
10	What is known about the long-term safety of repeated NAD+, and will you tell me in writing that it is not known?	A 2026 review says long-term safety data are lacking. 15
11	If this is offered for alcohol or drug withdrawal, who medically supervises it, and what is the evidence?	We found no controlled human trials, and the CAP Code expects supervision by a suitably qualified professional. 15, 20
12	Can I take independent medical advice, for example from my GP, before committing to a course?	The CAP Code expects marketers of invasive treatments to encourage independent medical advice. 20

What two questions do we add?

Two further questions come from us and not from a regulator source.

What is the total price, in writing? Prices on clinic websites vary by dose and by what is bundled, so it may help to have the full amount, and what it covers, set out before you agree. Our figures on published prices show the range clinics displayed, and they are not a quote.

What happens if something goes wrong? Ask who you contact, how a complaint is handled, which is covered by question 8 and by the last section of this page.

What are warning signs in clinic advertising?

Claims that NAD+ treats or prevents a disease, or that an injection delivers a health benefit without human trial evidence, are things the advertising rules and regulators have taken a close interest in.

• Medical claims. The CAP Code says medicinal or medical claims may be made only for a medicine licensed by the MHRA, VMD or under the EMA, or for a medical device with the applicable conformity marking. ²⁰
• Advertising a prescription-only treatment to the public. CAP says prescription-only IVs and vitamin injections cannot be advertised to the public, and rule 12.12 says the same for prescription-only treatments. ^20, 21
• Claims resting on oral supplement studies. CAP’s expert advice is that it is unlikely to be acceptable to extrapolate studies of regular supplementation to a one-off infusion. ²¹
• Addiction or withdrawal claims. The Observer reported in February 2025 that an MHRA spokesperson said anyone making medicinal claims about NAD+, including for addiction, is in breach of its regulations. That is a press report, and we found no MHRA-published page. ²²
• Infection or immunity claims. In 2020 the ASA upheld a complaint about NAD+ IV drip posts that said the drip could help protect against viral infections. ²³
• Discouraging medical care. The CAP Code says: “Marketers must not discourage essential treatment for conditions for which medical supervision should be sought.” ²⁰
• No clear answer on who gives it. The CAP Code says marketers offering invasive treatments may be asked to give full details of who supervises and administers them. ²⁰

A warning sign is a reason to ask more questions, and not proof that a clinic is doing anything wrong.

Does a listing here mean a clinic is approved?

No: a listing means a clinic says on its own website that it offers NAD+ by injection or IV and that we read that page; it is not an endorsement or an approval.

We do not rate, rank or recommend clinics. We do not assess a clinic’s clinical practice, its advertising or its regulatory history.

CQC registration, where we found it, does not mean the NAD+ service itself is regulated, and 45 of our 92 listed clinics were not found on the CQC register. ³

Our how we verify listings page explains what we do check, and the directory of listed clinics shows each listing with its verified date.

What could I tell my GP?

It may be useful to tell your GP that you are considering, or have had, NAD+ by injection or IV, and to share what you were given, when and by whom.

The NMC says prescribers need to know your full medical and prescribing history before supplying medicines, so a GP can only take that into account if they know about it. ¹⁰

Questions 6 and 8 above ask for the product details and symptoms that may help.

We cannot tell you what your GP will advise, and the sources we reviewed do not say.

What can I do if something goes wrong?

For urgent medical help, the NHS points you to 999 in a life-threatening emergency and to NHS 111 if you are not sure, and our side effects and safety guide gives the details.

After that, there are several routes, and the right one depends on what happened.

• The clinic. You can tell the clinic what happened and ask how it handles complaints, as in the question above.
• Suspected side effects. The MHRA’s Yellow Card scheme says anyone can report an issue with a medicine, vaccine, medical device, blood product or e-cigarette. ²⁵
• An advertisement. The ASA takes complaints through an online form and does not accept anonymous complaints. ²⁴
• The clinic’s regulator. You can look up the provider on the CQC’s find care services page in England, or on HIS’s provider search in Scotland. ^4, 8
• The clinician’s professional regulator. The NMC’s register shows whether a nurse is currently able to practise. ⁹
