Collection: Personal Physiology Maps

Understand what might be shaping how you feel.

Human physiology is complex.

Low iron isn't always just about iron.

Feeling tired isn't necessarily about sleep.

Drinking more water doesn't automatically mean you're better hydrated.

And the supplement, diet or practice that helped someone else may have very little to do with what your body needs.

Personal Physiology Maps are free guided tools designed to help you look more deeply.

Each Map starts with something you want to understand about your body and walks you through the different domains that may be contributing.

We look at your history, food and nutrient intake, medications and supplements, reproductive life where relevant, sleep, movement, environment, family patterns, previous investigations and — importantly — what you've already tried and what happened when you did.

We draw broadly from physiology and biochemistry, published research, clinical knowledge, traditional knowledge systems and lived experience.

And we don't pretend they all tell us the same thing.

Where something is well established, we'll tell you.

Where a mechanism is plausible but still uncertain, we'll tell you that too.

Where another knowledge system offers a useful way of viewing the problem, we'll allow it to speak in its own language.

And sometimes the most useful clue is something you've already noticed about yourself.

The aim isn't to diagnose you.

It is to help you discover:

what appears relevant to you
what you may reasonably explore yourself
what questions remain open
and what deserves a deeper conversation with your healthcare provider.

Free to explore. Full results included.

There is no paywall between you and your Map.

If you find one useful, you'll have the option to make a small contribution at the end. Contributions help us continue researching, testing and building more Maps.

Whether you contribute or not: you receive the same Map.
