Calibre found the root cause

I'm happy to say that because of Calibre the mystery (of my health situation) was solved. I don't think it would be possible with any other health service provider. Everyone does a little piece of the puzzle, but no one joins the dots and that is the really key thing.

I finally know where I stand

Calibre has given me a clear picture of my current health profile and what areas I need to work on and what my longer term risks are. I really value the care and insights from Calibre. The team is top notch and I feel that their method will help me reach my goals.

Just the actions that matter for me

It's been a really frictionless way of getting an understanding of where I am at health-wise, and what the biggest blockers are to my long-term goals. For anyone who wants to be healthy long term and actually wants to take some action, this will really help guide you into what are the most meaningful actions for you.

12 weeks in, I've made real progress

I've been trying to be on top of my health: tracking activities and food, occasionally doing blood tests and trying to interpret the results. Calibre has brought clarity and focus to my approach. In my first 12 weeks I have made substantial progress and look forward to continuing the journey to be the healthiest and strongest version of myself.

Doing cardio right

I would never have learned that I was doing too much zone 4/5 cardio. I would have just kept going… I really appreciate these fine nuances that you've caught.

My energy has improved

Three out of four weeks my energy level is superb across the different dimensions. My baseline has shifted up for sure. I feel like my sleep has also noticeably improved, which enabled me to do harder (workout) sessions.

Everything in one place

There are lots of aspects of my health to think about, from aging, exercise and nutrition, to family history and the risk of particular conditions. It's difficult to bring these together and get answers in the way that you want. With Calibre, I now have clarity and everything in one place.

Got more questions?

Talk to us, from general inquiries to discussing your health goals.

I've already tried Thriva or Neko. How is Calibre different?

Calibre is different both in what we measure and what happens next. We combine a 50+ biomarker lab test with five days of lifestyle tracking, wearables, health history and other diagnostics where useful. Your dedicated doctor and Calibre’s causal AI connect that evidence, then focus your plan on the few things that matter most for your energy and long-term health.

What if I've already tried more sleep, less caffeine, and supplements?

Generic advice only goes so far. Calibre looks at your physiology, diagnostics and real-life context to understand what’s actually driving your energy and focus on the few changes most likely to help.

How long until I feel a difference?

It depends on your health goal, your status quo on what’s driving it and how consistently you implement your plan. Calibre is designed to identify changes that can make a difference within 12 weeks, while some health measures may take longer to shift. We track what changes so you and your dedicated doctor can keep refining the plan.

Do I need to give up coffee, alcohol, or my current routine?

Calibre helps you understand which changes are most likely to improve your health, then works with you to build a plan that fits your life while still being effective enough to reach your goals. That might mean surprisingly small changes, such as swapping white rice for sweet potatoes or reducing high-intensity cardio. Ultimately, you decide what you do and don’t do.

Where do I get my blood drawn?

We partner with Randox clinics across England, giving you convenient in-clinic access to your Calibre lab test.

Why £39 a month? What's included?

Everything you need to work towards more energy today and better long-term health: a personalised 50+ biomarker lab test, your dedicated doctor, five days of lifestyle tracking, wearable integration, Calibre Energy Score, Health Assessment, personalised plan and ongoing diagnostic reviews. Advanced testing is included when appropriate. No hidden upsells or supplement commissions.

My GP said my bloods are normal. Can Calibre still help?

Yes. A result can sit within a standard reference range and still need to be understood in context. Calibre also measures markers that aren’t routinely included in standard testing and looks at your symptoms, family history, lifestyle and trajectory, not one number in isolation.

Can I pause or cancel my membership after I sign up?

Yes. If you need to pause your membership, message us and we’ll help arrange it.

If you cancel before completing your first lab test, you’ll receive a full refund.

If you cancel after your first lab test has been completed, a minimum of £177 is retained. Any amount paid above £177 is refunded pro rata for unused complete months remaining in your paid term.

To cancel, email refunds@getcalibre.com.

First-time members who qualify for our Money Back Guarantee are covered by that guarantee instead.

Is my data secure, and how is it handled?

Yes. Calibre meets UK GDPR and healthcare data-protection standards as a CQC-regulated care provider. Your health information is only accessible to you and the people involved in your care. We don’t share it with third parties without your consent, other than in exceptional circumstances where we have a legal obligation to do so.

What happens if you find something serious?

Your dedicated doctor reviews every result. If something needs urgent attention or specialist care, we’ll flag it promptly, explain what happens next and provide clear clinical documentation for onward care.
