How we verify clinic listings

How are clinics found?

We found clinics through Google Maps searches, then screened their websites for NAD+ content and read the NAD+ page on each clinic’s own site.

In practice that meant about 85 UK location searches, each combined with three or four service phrases, which gave 3,092 unique clinic websites. We screened those for an NAD+ page or mention and found 173, and we then hand-verified 92.

The scope is UK clinics and practitioners that list NAD+ injection or NAD+ IV on their own website. We leave out sellers who supply by post, home-pen sellers, wholesalers, trainers, vitamin-only IV clinics and non-UK sites.

We do not infer anything. If a clinic’s own site does not state a detail, that field stays blank.

What does a level A listing mean?

A level A listing means we read an NAD+ service page on the clinic’s own website and took the route, address and phone number from that site.

Level A listings have their own page that search engines may index. At the time of writing, 63 of the 92 listings are level A.

What does a level B listing mean?

A level B listing means we confirmed the clinic offers NAD+ on its own website, but one element is weaker.

The weaker element can be that the route is not specified, that the address comes from the clinic’s Google Business listing, or that the evidence is a blog post or a home-page mention.

Level B pages ask search engines not to index them, and they are left out of our sitemap, but you can still reach them from the directory and city pages. At the time of writing, 29 of the 92 listings are level B.

	Level A	Level B
NAD+ evidence	A service page on the clinic’s own site	Confirmed on the clinic’s own site, but weaker
Route, address, phone	All taken from that site	One element is weaker
Search engine indexing	Indexable	Not indexed
Listings today	63	29

How do we check the CQC register?

We matched all 92 clinics to the public Care Quality Commission register, and 41 matched a registered location.

We used the CQC’s open-data files of active locations (database as at 2 November 2026) and matched by postcode and address, phone, website domain and name. Each match was then checked against the live CQC location page on 11 November 2026 ¹.

The full result was:

• 41 clinics matched a CQC-registered location;
• 5 matched a CQC provider but not a registered location at the address on the clinic’s site;
• 45 were not found in the register files;
• 1 could not be checked, because it is in Wales, where the regulator is Healthcare Inspectorate Wales and its register could not be searched in the same way.

Of the 41 matches, 33 are high-confidence and 8 are lower-confidence. We show a CQC line only for the 33 high-confidence matches, and we do not show one where the match is weaker.

All but 2 of the 41 matches list “Treatment of disease, disorder or injury” among their registered activities, and the other 2 list only diagnostic and screening procedures ¹.

What does a CQC match mean, and what does it not mean?

A CQC match means a clinic’s location appears on the CQC register, and it does not mean the NAD+ service itself is regulated, assessed or approved.

CQC registration lists regulated activities, and CQC says the “treatment of disease, disorder or injury” activity does not include interventions carried out purely for cosmetic purposes ².

In a 2018 inspection, CQC itself found that an IV and intramuscular vitamin clinic’s wellbeing-only services were outside the scope of its registration ³.

Not finding a clinic on the register does not prove it is unregistered. A clinic can operate under another provider’s registration, or be outside CQC’s remit, and Wales and Scotland have their own regulators.

Some clinics also state on their own websites that they are CQC-registered. Where we show that, it is a statement by the clinic and not a check by us.

Our how to choose a clinic guide suggests asking a clinic for its registered provider name and location ID so you can check the regulator’s own register.

What do we not check?

We do not check clinical quality, safety, outcomes, prescribers’ registrations, the source or licence of the product, or the evidence behind any claim a clinic makes.

We do not inspect clinics, we do not publish reviews or ratings, and a listing is not an endorsement or medical advice.

We also do not check that a clinic is still operating after the date we verified it, so the verification date matters.

How often are listings re-checked?

We intend to re-verify every listing every 90 days, and each listing shows the date it was last verified.

The listings on this site were verified on 11 November 2026.

If a re-check finds that a clinic no longer meets the standard, we change its level or remove it.

How are published prices collected?

We record prices as displayed on the clinic’s own page on 11 November 2026, and they may have changed since.

Of the 92 clinics, 49 display some price on their own sites. Our statistics use only single-session prices with a clear route, which gives 46 prices: 36 for IV drips and 10 for injections.

IV and injection prices are never pooled. We leave out “from” prices, ranges, courses and packages, promotional offer prices, and any price where the dose, route or unit is not stated.

We show neutral labels such as “NAD+ IV drip, 250mg, single session” and drop rows where a clinic’s own label contains a claim.

Every statistic is shown with the number of prices behind it, and the cost guide explains what the figures do and do not tell you.
