NAD Injections in the UK: Clinics and the Rules

Over the last twelve months the MHRA has taken seizures of improperly distributed medicines worth around £64.4 million, amounting to a total of 28.5 million doses. The majority of seized medicines are prescription medicines rather than NAD+, but it proves to be a good sign that the UK regulator is very active in the unregulated part of the market, and that the NAD injections sold in UK centres are located there.

This guide helps you understand who supplies NAD+ in the UK, what kind of rules exist for clinics and research products, what checks I would do before making a payment. It's about the system, not whether NAD+ is suitable for you, as that is for your doctor to decide.

Who offers NAD injections in the UK

NAD injections available to UK consumers are mostly found in private clinics, med-spas, and IV bars, either in the form of IV drips or as injections. Each clinic sets the price independently, resulting in dramatically different prices for NAD+ without any standard pricing.

Alongside the clinics, research vendors, mostly based abroad, sell NAD+ as research-use powder and sprays. Food supplement retailers sell oral precursors such as NMN and NR, which are a different category with different rules. Our page on NMN vs NAD explains how those relate.

One thing to note is that you will not find an NHS pathway. NAD+ as an injection is not a confirmed medicine; hence it does not qualify for being prescribed by the NHS.

How UK medicines law treats NAD+

Products in the UK are categorized regarding their functions. By virtue of Human Medicines Regulations of 2012, products that have therapeutic effects on injury, mental activity, and metabolism can be considered medicines and, as such, fall under licensing requirements as well.

The principle carries more importance than its substance. NAD+, being a natural coenzyme, will fall under the laws of medicines at the point when the seller or the clinic verifies that it can treat a specific condition. Thus, sellers who claim that the unlicensed product has medicinal properties put themselves at risk of selling a product that weighs as an unlicensed medicine.

Labels including "meant for research only" and "not for human consumption" do not somehow make a product lawful for supply to humans, and they do not indicate that it was manufactured according to medical standards. To me, these labels say more about the seller’s intention to do business.

The MHRA's current focus on clinics

In April 2026 the Guardian reported that the MHRA was investigating UK peptide clinics that make medicinal claims about unregulated peptides. Many providers in that market rely on "research only" labelling.

The same reference did not state that selling these compounds is illegal by itself. The key issue is with what is claimed. A clinic that guarantees the reversal of aging, the treatment of fatigue, or the reduction of weight with an illegal product occupies a different legal position than a clinic that carefully articulates its services.

For context, in the US NAD+ as an injectable is not an FDA-approved drug. When the FDA sent warning letters to five online peptide vendors on 24 August 2026, NAD+ was not among the products named, but the agency made clear it judges a whole website, including disease claims and dosing guidance, not just the label.

Checks to make before booking a clinic

The relevant verification steps provided by NAD clinics across the UK relate not to the photographs of the clinic but about people and paper documents. I will ask the questions written below before booking any NAD drip or injection:

1. Who carries out the consultation, and what is their professional registration?
2. Who decides whether the treatment is suitable for you, and do they ask about your medical history and current medicines?
3. Where does the clinic source its NAD+, and can it show quality documentation for the batch?
4. What does the clinic do if you feel unwell during the session?
5. Does the clinic's website promise to treat or cure anything? If so, treat that as a warning sign.

Our page on what a NAD drip session involves covers the session itself, and NAD injection side effects lists what clinics commonly report.

Buying research products from abroad

Research vendors such as Real Peptides are US-based and price in US dollars: the NAD+ multi-dose vial is listed at $60.00 (US dollars) and the NAD+ liquid spray at $120.00. Both are labelled research use only, with no consultation.

There’s no confirmation that this supplier ships to the UK. Before you place your order, it’s important to check whether they ship to the UK on their website. There can also be currency and card charges when making a dollar purchase. Further, customs can detain the shipment or additional VAT and taxes may be charged. The free-shipping limits that managers of US companies are providing refer to US priorities.

Reporting a problem

In case you experience any adverse reaction from using any item or treatment, you should report it to the MHRA's Yellow Card system. This includes treatments from clinics and products purchased via the internet.

In case you come across a pharmacy selling prescription medications without any prescription via social media or expecting payment via bank transfer or cryptocurrency, report them to the authorities. In order to confirm the legitimacy of an online pharmacy, look up its name on the General Pharmaceutical Council (GPhC) register to see if it is duly licensed.
