Frequently asked questions

Talk to us, from general inquiries to discussing your health goals.
I've already tried Thriva or Neko. How is Calibre different?
Those services give you data. Calibre is designed to deliver outcomes. That’s why we have personalised blood tests, and assess your lifestyle, health history and wearable data in order to build the complete picture of your health. This is joined up and reviewed by a dedicated doctor who provides you with a holistic health assessment and then builds a plan around the 2 to 3 specific things actually driving your energy and long-term health. Not another dashboard to decode alone.
What if I've already tried more sleep, less caffeine, and supplements?
You're not alone. Most Calibre members have already tried what generic advice recommends. That's why we don't start with generic advice. We start with your specific context and data, find what's actually driving your energy, and build a plan around the 2 to 3 things that matter for your body. The cause of low energy often differs from person to person.
How long until I feel a difference?
Most members report noticeable improvements within 4 to 8 weeks. Meaningful change in your biomarkers typically shows in the first re-test at month 6. Your Energy Score is remeasured every quarter so you can see progress objectively, not just how you feel on any given day. Results may vary and will also depend on you implementing the plan.
Do I need to give up coffee, alcohol, or my current routine?
Maybe. Calibre isn't a restrictive protocol. Your dedicated clinician looks at what you're currently doing and identifies the specific changes that will move your energy for your body. Often it's not what people expect. One member's energy improved by swapping white rice for sweet potatoes. Another's by reducing high intensity cardio. We will show you the full picture and provide you with different choices on how to improve your energy.
What if my results indicate something serious?
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.
Where do I get my blood drawn?
We partner with clinics across London, giving you a choice of locations and flexible appointment slots.
Why £39 a month? What's included?
Everything. Your 50+ biomarker panel, your dedicated doctor, quarterly reviews, five days of lifestyle tracking every quarter, wearable integration, your Calibre Energy Score, your personalised plan, advanced testing where indicated (DEXA, VO₂ max, CGM, hormone panels). No upsells. No supplement commissions. Comparable care assembled separately would cost around £5,000 a year.
My GP said my bloods are normal. Can Calibre still help?
Yes. Standard NHS panels are designed to detect disease, not to identify what's driving your energy or what’s optimal for you. Being within reference range doesn't mean your body is running at its best. Calibre tests specific markers most GPs don't run, including leptin, fasting insulin, Free T3, ApoB, and interprets them in the context of your full picture, so we can find what's driving your energy even when your bloods look fine.
Can I pause or cancel my membership after I sign up?
Yes to both. If you need to pause or cancel your membership for any reason, just reach out to us via WhatsApp, and we'll sort it out.
Is my data secure, and how is it handled?
We are privacy-first by design, and our data practices are built to meet the latest UK data protection and GDPR standards. We follow CQC-regulated policies that apply to UK clinical care providers.
Your health data is only accessible to you and your clinical team. It is not shared beyond that without your explicit consent, except where legally required.
