Dr Reinhold's approach

Calibre gave me a much clearer understanding of my health than any standard check-up I've had before. Instead of just receiving test results, everything was explained in context with practical, personalized recommendations that were easy to follow.

Maya

Really smooth experience so far - loved the initial assessment experience including the in-depth chat with my dedicated calibre doctor on the implications of my results. It’s great to have all my data at my fingertips and someone trustworthy to connect on it.

Luis

Great team focused on offering value to their users. I'm a GP myself and quite health-conscious, and I love that Calibre offers blood tests that are not part of classic NHS panels (e.g.: ApoA & ApoB, DHEA, etc.). Learned a lot about my own health.

Aditi

I built Calibre because my energy tanked and I couldn't get it back.

In 2019, at the peak of a demanding job, my energy tanked. I had been through ten years of high-intensity swimming and another ten years at N26 in demanding growth roles. The tools that had worked for me for two decades stopped working

I couldn't sleep well anymore. That trickled down into my focus, my clarity, and how I felt overall. Then I met Dr Reinhold. He had an approach I'd never seen from a doctor before. He looked at my full picture: my sleep, my food, my stress, my bloods. He saw sleep as the key thing to get back on track and asked me to start monitoring with an Oura ring.

For the first time, I understood what was happening in my body, why, and exactly what I could do about it.

Based on what he saw, he made specific changes: dimmer lights at home, blackout curtains, blue-light-blocking glasses for late screen work, shifting my dinner time earlier, and a few specific supplements. He asked me to re-prioritise strength training and gave me new meal plans with more nutritious breakfasts.

Within six months, my energy was back. I was sleeping well, performing under pressure at work, and feeling like myself again. That's the level of proactive care we built Calibre to give people.
