Is NAD+ Legal in the UK? MHRA Status and Novel Food Rules Explained

Is NAD+ legal in the UK? Yes — it's legal to buy and use NAD+ self-injection kits here, but that's a different question from whether NAD+ is a licensed medicine, and it isn't. NAD+ injections are sold in the UK as an unlicensed wellness product, which means the MHRA (the UK's medicines regulator) hasn't reviewed, approved or authorised them the way it reviews a prescription drug. Understanding the gap between ‘legal to sell’ and ‘licensed as a medicine’ is the key to understanding how NAD+ is actually regulated here.

Is NAD+ Legal to Buy and Use in the UK?

Yes, in the sense that no UK law bans the sale or personal use of NAD+ self-injection kits, and sellers like ours operate openly within the law. What NAD+ doesn't have is a UK marketing authorisation — the formal licence the MHRA grants to a product it has independently assessed for quality, safety and efficacy as a medicine. Without that licence, NAD+ sits in a category often called ‘unlicensed’ or ‘borderline,’ alongside a range of other wellness injectables sold directly to consumers. If you're also weighing up whether NAD+ injections are right for you medically rather than legally, our guide on who should avoid NAD+ injections covers the health-based precautions separately.

How the MHRA Decides What Counts as a ‘Medicine’

The MHRA doesn't classify a product as a medicine purely because of what it contains. According to the regulator's own guidance on borderline products, a product is treated as ‘medicinal’ if it's presented as addressing disease, or if it's intended to restore, correct or modify a body function through a pharmacological, immunological or metabolic action. Crucially, the same ingredient can be marketed as a cosmetic, a food supplement or a medicine depending almost entirely on the claims made about it — not just what's in the vial. In practice, the regulator weighs the explicit and implied claims made about a product, the ingredient's pharmacological properties, how it's intended to be used, whether comparable licensed products already exist, and how it's presented across packaging, websites and marketing.

Because UK sellers market NAD+ as a general wellness product rather than as something that addresses a named medical condition, it sits on the food-supplement side of that line. That's also why you'll notice reputable NAD+ sellers avoid language claiming the product treats, cures or prevents disease: crossing that line in marketing, not the ingredient itself, is what would reclassify a product as an unlicensed medicine being marketed unlawfully.

Where UK Novel Food Law Fits In

Separately from medicines regulation, there's a second layer worth knowing about: novel food law. In the UK, a ‘novel food’ is broadly any food or ingredient that wasn't eaten to a significant degree before May 1997, and it generally needs safety authorisation from the Food Standards Agency before it can be sold as a food or drink ingredient. NAD+, and its related precursor NMN, fall into this grey area too — neither currently holds a UK novel food authorisation as an oral ingredient, which is part of why NAD+ is marketed in the UK mainly as an injectable wellness product rather than as a food or drink additive. Where companies do pursue novel food authorisation, it's a genuinely slow process: typically 18–24 months, backed by toxicological and metabolic safety data, not a formality.

What ‘Unlicensed’ Really Means for You as a Buyer

The practical upshot is that NAD+ injections don't come with the safety net a licensed medicine does. There's no MHRA-approved patient information leaflet listing official contraindications, and far less independently reviewed long-term human safety data than you'd find behind a prescription drug. The NHS's own guidance on unlicensed medicines makes a similar point about products outside the standard licensing framework: more of the responsibility for checking suitability and quality sits with the buyer and supplier rather than being guaranteed by a regulator. That's exactly why we're upfront about NAD+'s unlicensed status rather than burying it in small print — and it's also why some of the claims you'll see about NAD+ elsewhere online don't hold up. Our breakdown of common NAD+ myths digs into several of those claims in more detail.

Frequently Asked Questions

Will NAD+ ever become a licensed medicine in the UK?

It's possible, but there's no indication it's imminent. A company would need to sponsor clinical trials and submit them to the MHRA for formal marketing authorisation — a separate and generally longer undertaking than pursuing novel food status for an ingredient.

Is it illegal to import NAD+ injections into the UK for personal use?

Buying NAD+ injection kits for personal use from a UK-based seller is not illegal. Bringing in larger quantities from abroad can raise separate customs questions, so buying from a UK-based supplier avoids that complexity altogether.

Does ‘unlicensed’ mean NAD+ hasn't been tested for safety at all?

No — it means NAD+ hasn't gone through the MHRA's formal medicine licensing assessment. Some research on NAD+ and related compounds exists in scientific literature, but it hasn't been reviewed and approved by a regulator the way a prescription medicine's evidence package is.

Can NAD+ injections be sold alongside claims that they treat a specific condition?

No. The moment a seller claims a product treats, prevents or cures a named medical condition, UK rules treat that product as an unlicensed medicine being marketed unlawfully, regardless of what it's made from. Reputable NAD+ sellers stick to general wellness language for exactly this reason.

What should I check before buying an NAD+ injection kit in the UK?

Look for a UK-based supplier that's transparent about NAD+'s unlicensed status, lists ingredients and sourcing clearly, and gives clear usage and storage guidance rather than medical claims. Checking with a GP or pharmacist before starting, particularly if you take other medication, is also worth doing given the limited regulatory oversight.
