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.

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.

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.

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.

Your dedicated doctor reviews every result. If anything requires urgent attention or specialist input, we'll flag it immediately and provide a GP referral letter for onward care. Calibre works alongside NHS care, and is not a replacement for primary or acute care.

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

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.

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.

Calibre is available for adults aged 18 to 65 living in England, with a particular focus on 25 to 55-year-olds who are broadly well and looking for a holistic, proactive and expert-led approach to their health.

Calibre works alongside traditional healthcare and is not suitable as a first point of contact for new or urgent health concerns. Calibre is not currently suitable if you: are under 18 or over 65; are not resident in England; are experiencing new, worsening or urgent symptoms not yet discussed with a doctor, including mental health symptoms; are currently pregnant; or have a health condition that is unstable or not well controlled.

You’ll create your Calibre account and set up WhatsApp as your direct channel to the Calibre team. The app then guides you through completing your health questionnaires, connecting your wearable, uploading past medical records, booking your lab test and choosing your five-day lifestyle-tracking window.

Because health is a trajectory, not a snapshot. As we learn more about you and measure what changes, your Health Assessment and plan become more precise over time.

Week 1: Build your baseline
Complete your health questionnaires, connect your wearable, upload past medical records and book your lab test.

Week 2: Diagnostics
Complete your personalised blood and urine test at a Randox clinic, alongside five days of lifestyle tracking covering energy, blood pressure, nutrition, activity and sleep.

Week 3 to 4: Understand your health
Once all your information is complete, your dedicated doctor and Calibre’s causal AI bring it together in your Health Assessment. You meet your dedicated doctor to understand what’s driving your energy and long-term health and agree your first personalised plan.

From there
We track what changes, learn from the results and continuously refine your plan.

Your membership starts with a personalised blood and urine lab test covering 50+ biomarkers, selected to build a meaningful baseline for your energy and long-term health.

Every six months, you and your dedicated doctor decide which diagnostic will add the most value. This may mean targeted blood-marker retesting or an advanced test such as DEXA, VO₂ max or CGM. Your full blood and urine lab test is repeated annually.

This cycle continues throughout your membership.

We personalise our 50+ biomarker baseline test by asking you a targeted set of questions about your past health, current context and goals. Your answers help us select the markers most relevant to understanding your energy and long-term health.

An annual health check gives you a snapshot. Calibre is built around your trajectory. We decide what to measure, interpret it in the context of your full story, act on what matters and track what changes over time, working towards more energy today and lower long-term health risks.

A wearable can tell you something’s off, but it can’t tell you why. Calibre combines wearable data with diagnostics, lifestyle and your health history to understand what it means for you and what to do about it.

Calibre was co-founded by physician and sports scientist Dr Reinhold Innerhofer. Every member has a dedicated doctor, supported by Calibre’s clinical methodology and causal AI. Clinical care and interpretation are delivered directly by Calibre as a CQC-regulated care provider.

No. Calibre is your primary relationship for proactive health, working alongside traditional healthcare. We help you understand what’s driving your health and how to improve it over time. When something requires specialist or urgent care, your dedicated doctor guides you to the right service.

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.

Yes. Family history shapes what we measure and how your results are interpreted. A “normal” ApoB reading can mean something very different if your father had a heart attack at 55. Your dedicated doctor interprets every result in the context of your individual risk profile.

Yes. Lp(a) is included in your baseline lab test. It is a largely genetic cardiovascular risk factor elevated in roughly 1 in 5 people, and many have never been tested. If yours is elevated, your dedicated doctor will explain what it means in the context of your wider cardiovascular risk and which modifiable factors matter most.

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.

Yes. We provide clear clinical documentation you can share with your GP or specialist, and can facilitate direct sharing where appropriate and with your consent.

Yes. Your membership can include advanced diagnostics such as DEXA, VO₂ max and CGM, chosen with your dedicated doctor when they are the most useful next test.

For specialist diagnostics we don’t yet offer directly, such as coronary calcium scoring, your dedicated doctor can help you understand whether they are appropriate and guide you to the right specialist service.

Everything you need to work towards more energy today and better long-term health: a personalised 50+ biomarker lab test, your dedicated doctor, Health Assessment and personalised plan, wearable and lifestyle integration, regular reviews and follow-up diagnostics. Advanced testing is included when appropriate. No hidden upsells or supplement commissions.

We review your diagnostics every six months and remeasure when it can improve the next decision.

For example, at Month 6 you may repeat targeted markers or choose an advanced diagnostic. At Month 12, we repeat your full blood and urine lab test. At Month 18, we again choose the most useful targeted or advanced diagnostic.

Those months are examples of the ongoing cycle, which continues for as long as you’re a member.

Yes. You can pause or cancel anytime with no penalties. If your health assessment does not give you clarity, we offer a full money-back guarantee. We do not lock members in.

We arrange your blood and urine lab test through Randox clinics across England. Once you’ve completed your health questionnaires, lab test, five-day lifestyle tracking and uploaded your past medical records, your dedicated doctor and Calibre’s causal AI bring everything together in your Health Assessment and personalised plan.

Calibre starts with the outcome, not the size of the test panel. We combine a 50+ biomarker lab test with lifestyle, wearables and health history, then your dedicated doctor and Calibre’s causal AI connect the dots and prioritise the few actions most likely to improve your energy and long-term health. We then keep measuring what changes over time.

Most people haven’t done too little. They’ve tried too many things without knowing which matter. Calibre is designed to identify the few factors most likely to make a difference for you.

Yes. Calibre integrates with leading wearables and health apps, so your sleep, activity, heart rate, HRV and recovery trends become part of the picture your dedicated doctor interprets alongside your diagnostics and lifestyle.

Yes. Your 50+ biomarker baseline includes markers such as ApoB, Lp(a), fasting insulin, HOMA-IR, leptin, Free T3, DHEA-S and SHBG. We don’t maximise biomarker count for its own sake. We select markers because they help us understand the drivers of your energy and long-term health.

Yes. Your dedicated doctor takes a proactive, evidence-based approach to performance and long-term health, combining diagnostics, physiology, lifestyle and your health trajectory rather than looking at isolated results. Every recommendation is grounded in high-quality evidence.

We look at the systems that shape energy, including sleep and recovery, metabolism, hormones, inflammation, fitness, and mind and mood. We combine those with your diagnostics and real-life context to understand what’s driving your energy and which few levers matter most.

Wearables infer recovery and readiness, but they can’t directly measure how energetic you feel. The Calibre Energy Score takes under 10 seconds and measures four dimensions of lived energy: wakefulness, drive, mood and calm. We then compare that outcome with the biological and lifestyle factors that may be driving it.

Every six months, you and your dedicated doctor decide which diagnostic step will add the most value.

For example, at Month 6 that may be targeted blood-marker retesting or an advanced diagnostic such as DEXA, VO₂ max or CGM. At Month 12, your full blood and urine lab test is repeated. At Month 18, you again choose the most useful targeted or advanced diagnostic.

This cycle continues for as long as you’re a member. The principle is simple: test when the result can improve the next decision.

We look beyond whether a marker sits inside a standard reference range. Your dedicated doctor considers what is optimal in your individual context and, importantly, your trajectory over time.

As we build your longitudinal data, some markers can also develop a more personalised range based on your own healthy baseline. That helps us distinguish what is normal for the population from what is normal and optimal for you, and spot meaningful changes earlier.

We start with what you’re already doing. If it’s working, we keep it. If something important is missing, we add it. And if you’re spending time or money on things that add little value, we’ll tell you what you can stop, so you can focus on the few things that matter most.

Yes. Your dedicated doctor will review what you’re already taking and guide you on what is worth keeping, changing or stopping. We often find people are spending money on supplements that add little value and can simplify their routine. Calibre doesn’t earn commissions from supplement companies, so recommendations are based on your health and the evidence.

Only on your request. If you want to share your results with your GP, cardiologist, endocrinologist, or specialist, we make that straightforward with clean clinical documentation. Your data is yours. We facilitate sharing when you ask; we never share without explicit consent.
