Beyond the Badge: A Practical Guide to Vetting Health-Tech Claims in 2026

Health technology is no longer confined to hospitals. It sits in pharmacies, arrives through the post and runs on the phone in your pocket. That is broadly good news for access, but it places a new burden on the public: judging whether a product's claims are proportionate to its evidence. Phrases such as 'clinically proven', 'NHS-approved' and 'lab-tested' sound authoritative. They are not self-explanatory. At Sarissa Biomedical, our editorial work is concerned with translating biomedical evidence into everyday care, and that includes helping readers ask better questions before they spend money on a device or app.

Start with the intended purpose

A useful first question is not 'Does it work?' but 'What is it legally and clinically claiming to do?' In the UK, products that are intended to diagnose, prevent, monitor, treat or alleviate disease are generally medical devices and fall under the Medicines and Healthcare products Regulatory Agency (MHRA) framework. Products positioned as general wellness items may sit outside that framework, which can mean lighter scrutiny. A sleep tracker that encourages healthier habits is not the same as a device that claims to detect sleep apnoea. If the marketing implies a medical purpose, the evidence and regulatory expectations should be correspondingly stronger.

What 'clinically proven' can mean

'Clinically proven' is a marketing phrase, not a regulatory category. It may sit alongside a randomised controlled trial published in a peer-reviewed journal, or it may rest on a small internal study with no comparator, no published protocol and no clear clinical outcome. Readers should look for the citation itself, not the badge. A useful evidence summary will say who was studied, how many people took part, what the product was compared with, what was measured, how long the study lasted and whether the results were independently scrutinised. A claim based on 30 healthy volunteers over two weeks is not equivalent to a claim based on a diverse NHS population over twelve months. Words such as 'proof' deserve particular caution: clinical evidence is usually probabilistic, incremental and bounded by the study's design.

'NHS-approved' and 'lab-tested'

The NHS does not generally 'approve' consumer health products in the way the phrase suggests. A product may be available through an NHS supply route, mentioned in NHS information, evaluated by the National Institute for Health and Care Excellence (NICE) for a specific use, or used by an NHS organisation locally. Each of those is narrower than a blanket endorsement. 'Lab-tested' is similarly thin without context. It may mean the product was checked for electrical safety, that a sample was analysed for purity, or that a prototype was tested in controlled conditions. It does not, by itself, demonstrate clinical benefit.

Regulators and advertising rules

The MHRA operates UK medical device regulation and maintains public information about registered devices and manufacturers. Registration is not a consumer endorsement of every claim, but a missing or inconsistent regulatory trail is a warning sign. Advertising in the UK is also governed by the Advertising Standards Authority (ASA) and the Committee of Advertising Practice (CAP) Code, which require claims to be substantiated before they appear. The ASA publishes rulings on health claims, and its website is a practical resource for readers who want to see how evidence standards are applied. If a product's marketing feels evasive, check whether the manufacturer names a regulatory route, a UK responsible person and a complaints process.

Red flags worth noticing

Be wary of claims that a product can diagnose or treat a wide range of unrelated conditions, especially where the mechanism is described in vague terms such as 'energy', 'balance' or 'cellular optimisation'. Other warning signs include a lack of named manufacturer or UK contact details, heavy reliance on testimonials rather than data, countdown offers, claims of 'no side effects', before-and-after imagery presented as proof, and citations that cannot be found or do not match the claim. Artificial intelligence is not itself evidence. A product may use machine learning, but the relevant questions remain the same: what was it trained on, how was it validated, in whom, and against what comparator?

A checklist before you buy

1. Write down the exact health claim. Is it wellness, monitoring, diagnosis or treatment?
2. Check the manufacturer's regulatory information. Is there a UKCA or CE marking where relevant, and a clear intended purpose?
3. Ask for the evidence citation. If there is no reference, treat the claim as unproven.
4. Read the study summary. Who was studied, and do those people resemble you or the person you care for?
5. Look for a comparator. Compared with what: usual care, a placebo, a sham device or no intervention?
6. Check whether the outcome is clinically meaningful, not merely a sensor reading.
7. Search the ASA and MHRA websites for the product, manufacturer or claim.
8. Review data privacy and security if the product is an app or connected device.
9. Ask what clinical support exists if the device produces an alarming result.
10. Consider whether an NHS route, GP appointment or pharmacist assessment would answer the same question at lower cost.

What good looks like

Good health-tech communication is rarely breathless. It states the intended purpose, cites peer-reviewed evidence, describes limitations and avoids implying that a consumer product replaces clinical assessment. It gives a UK contact point and explains what the device or app is not designed to do. That kind of restraint may be less exciting than a badge, but it is more useful. Translating research into everyday care depends on readers being able to distinguish between a regulated medical claim and a marketing impression. The checklist above is not a substitute for professional advice, but it is a practical way to make that distinction before you buy.
