Frequently asked questions

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 arrange your blood and urine lab test through 60+ Randox clinics across the UK, or at your home or office with a Heim Health nurse.

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.
