Still unwell after doing everything right? Let's find your root cause.
I'm William Dickinson, a gut health coach. I've worked with 1,000+ clients worldwide to understand why their symptoms are happening and what to do next — step by step, with no cookie-cutter plans.
Which path is right for you?
Everyone's gut story starts somewhere different. Find where you are, and the right first step for you.
Antibiotics threw your gut off, and you want to put it right.
- Whether your course starts next week, you're on it now, or it ended years ago
- The exact order to protect and rebuild, what to take, what to avoid, and when
- Plain-language steps you can follow at home, no guesswork
- Built from the same protocol William uses in one-to-one practice
React to food, heat, stress, even your own home? There's a reason, and there's a plan.
- Find out what's actually going on: histamine intolerance, MCAS, or the gut problem driving both, so you stop treating the wrong thing
- Eat more, not less: the full food lists plus the reintroduction method, so you get off the ten-food diet instead of living on it
- Five phases, one at a time, each with a checklist, so you always know the next step and never wonder if you're doing it wrong
- The exact protocol William uses with 1:1 clients (a first session is €250), for €17, with the histamine cup tracker and flare detective sheet included

“I have learned so much more from William during a relatively short time, than from all other sources (doctors, groups, communities) combined, for the last five years.”
