Welcome to Cortigenix — our mission and what we believe

Our mission is simple: to help people live longer, healthier, and happier lives. We believe that understanding what's happening inside your body is the first step towards making the lifestyle changes that actually matter — and that the key to improved health is measuring what's happening over time, not just taking a snapshot on one particular morning.

What we believe

Inner health insight comes before change. You can't meaningfully improve what you can't measure. Understanding your biological status — in particular your long-term cortisol patterns — gives you a factual basis for lifestyle decisions, rather than guesswork.

The trend matters more than the moment. Short-term changes to lifestyle rarely produce lasting improvements on their own. We believe the key to genuinely better health is understanding how your body is responding to your lifestyle over time, and making adjustments based on that data.

Prevention is proactive, not reactive. Most people don't test their health until they have a symptom. We believe prevention should start long before that — giving people the insight they need to act while there's still time to make a real difference.

Your genes are not your destiny. Genetics play a role in health, but lifestyle is a powerful modifier. Knowing how your choices are affecting your biology — and having the data to adjust those choices — means your long-term health is far more within your control than it might seem.

Why hair cortisol?

Cortisol is one of the most informative and wide-ranging hormones in the body. Hair cortisol testing gives a 3-month average — the kind of stable, long-term biological measure that actually reflects how your lifestyle is affecting you. It's the HbA1c for stress hormones: one test, three months of insight.

We're proud to work alongside researchers at the University of Nottingham, King's College London, University of Auckland, and the University of Oxford. Our test is independently validated and our research partners include some of the world's leading scientists in stress, health, and longevity.
