About Us

We believe everyone should have access to information that tells them what’s going on inside their body - so they can take action to optimise their health - and to avoid illness now and in the future.

The key to improved inner health is to know what’s happening within your body over-time, not just a snapshot.

So we bought together a team of world leading scientists to develop our Cortisol-Over-Time (COT) test.

Our mission is to empower millions of people around the world with the information they need to take control of their inner health, and provide insights that will help optimise their biological wellness so that they can live longer, healthier and happier lives.
