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.

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.

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.

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.

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.

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.

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.

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.

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.
