If you've been looking at Superpower from the UK, you've probably been drawn in by the headline: 150+ biomarkers a year for $349 (it was $199 until 1 September 2026). It sounds like a breakthrough. And for Americans who've only ever had 20-marker GP panels, it is.

But there are two things to know upfront. Superpower is not available in the UK. And even where it is available, the core membership tests blood only: there’s no DNA test, and gut testing is an add-on. This article covers:

What is Superpower?

Superpower is a US-based, venture-backed health testing platform. It positions itself as a health super-app for preventative wellness. Membership costs $349 a year (up from $199 on 1 September 2026). For that, members get 150+ biomarkers a year across two blood draws, a baseline and a retest, taken at Quest labs or at home in some US cities. They also get a digital dashboard with colour-coded results and a biological age estimate, and AI-generated health recommendations.

The model is a relatively low entry price for blood testing, with extra diagnostics and supplements sold through the platform. What you spend beyond the $349 membership depends on how many of those you add.

Why UK residents are searching for Superpower

The appeal is straightforward. UK residents who follow the US longevity and biohacking space see platforms like Superpower and Function Health offering broad biomarker panels for a fraction of what private clinics charge here. What they are actually looking for is:

• More visibility into their health than the NHS provides

• Affordable access to advanced blood markers like ApoB, Lp(a) and HbA1c

• A platform that interprets results rather than returning raw lab numbers

• Trend tracking over time, not a single annual snapshot

• An action plan alongside their data

This demand is real and growing. NHS waiting lists, limited routine blood panels, and rising awareness of preventative health are all driving UK consumers towards self-pay testing.

Superpower is not available in the UK

Superpower currently operates in the United States only, with blood draws at Quest labs or at home in some US cities. At the time of writing there is no UK service, no UK lab partner, and no announced timeline for international expansion.

Beyond geography, there are structural limitations worth understanding even if Superpower were to launch here:

Even at $349, the price is compelling as a headline. But the real cost of acting on your results (add-on diagnostics and supplements) can be significantly higher, and the membership itself doesn't include the DNA or microbiome testing that gives blood results their full context.

The UK alternative: Stride

For anyone in the UK searching for comprehensive preventative health testing, Stride's StrideOne membership is a UK alternative, and it works differently.

Rather than starting with a low-cost blood panel and upselling add-ons, Stride wraps everything into a single annual membership: DNA, gut microbiome and blood testing (500+ biomarkers), quarterly 1:1 video consultations with a Stride expert, Stride BioAge to track your biological age, and the MyStride dashboard for your results. Members also get 25% off Stride supplements. Where Superpower sells you the starting point and asks you to build from there, Stride gives you the full stack from day one.

Superpower vs Stride: side by side

The real cost of each approach

Superpower's $349 headline is still low for what you get in the base panel, which covers two blood draws a year. But the question is what happens next. If you want to act meaningfully on your results (understand your gut health, add more specialised panels, take supplements), the costs add up quickly.

The comparison shifts when you look at total cost of ownership rather than entry price. Stride's membership includes the testing, the retesting and the practitioner time, with a member discount on supplements. Superpower's membership is the starting ticket, and what you add after that is all incremental.

Why blood testing alone is not enough

Blood biomarkers are powerful. They show your current metabolic state, nutrient levels, organ function and inflammation. But they represent one layer of a multi-layered biological picture.

Who each approach suits

Superpower may suit you if

• You are based in the United States

• You want a relatively low entry price for blood testing

• You are comfortable managing your own follow-up and supplement choices

• You want access to prescriptions and peptides through a digital platform

• You don’t need DNA or microbiome testing, or scheduled one-to-one consultations

Stride suits UK residents who want

• Comprehensive multi-omic testing across DNA, blood, gut microbiome and biological age

• 500+ biomarkers, with blood and gut retested every six months

• Quarterly 1:1 video consultations with a Stride expert

• 25% off Stride supplements, with expert input on what fits their results

• A single membership that covers testing, retesting and consultations
