Cut out gluten. Try another probiotic. Feel better for a week, then back to square one. You're not doing it wrong, you're doing it blind. We read your gut at species level and build a protocol around what it actually needs, not what worked for someone else.
Read at species level, signed off by our science board. A reading, not a questionnaire.
Pick the one that fits best.
Turn this into your formula.
A reading confirms which pattern is really yours, then we build a formula from it, dosed to your gut. Nothing's charged until it's made.
Every fix on the shelf is a guess, built for an average gut, not yours. That's why the relief never lasts. Sound familiar?
Gluten, dairy, onions, coffee. The list of "maybe it's this" gets longer and your meals get smaller.
A different strain, a bigger CFU count, whatever the reviews say. No way to know if it's right for your gut.
A good week. Maybe two. You start to think you cracked it. Hope is the expensive part.
The bloating returns. You never learned why, so you're guessing again, from scratch.
This is the guessing loop. A reading is how you leave it.
Across the guts we've read, the same handful of imbalances come up again and again. Your symptoms almost certainly point to one of them, but several look identical from the outside. Which is exactly why guessing fails.
That bloated, gassy, over-full feeling after meals, even normal-sized ones.
Bloating that turns up daily, no matter how carefully you eat.
Everything moves slowly, and all that "healthy fibre" doesn't seem to help.
Foods that never bothered you suddenly do. Your gut feels easily irritated.
After antibiotics, illness or travel, it takes far too long to feel normal again.
Low energy, off your food, reacting to more and more. Everything feels run down.
When life gets stressful or sleep slips, your gut is the first thing to feel it.
Sometimes your gut is doing well, and the smart move is to protect it, not force change.
The quiz gives our best guess from your symptoms. The reading tells you which is actually yours.
It starts with a simple at-home sample. We read it properly, every strand of DNA, down to the species, and the functional genes that tell us what your gut can actually do with what you eat. Not a colourful score. A real map of what's driving your symptoms.
That's the difference between a guess and a reading. A probiotic off the shelf hopes it's right. Your reading knows which microbes are missing, which fibres your gut can ferment, and where the discomfort is coming from.
From that we build your protocol: only the components your biology calls for, each dosed to your gut, posted monthly, presorted. And because your gut keeps changing, it recalibrates each cycle.
How we read a gut →Not a cupboard of bottles you're guessing at. A small, considered protocol built from what your gut actually showed, presorted and travel-ready, so the only thing you have to do is take it.
Morning
The morning foundation, built from what your reading found you're short on, to start the day steady.
Evening
A calmer, overnight layer, added only when your reading calls for it. Nothing here by default.
Anytime
The living layer. Precision prebiotics, fibre matched to your gut's fermentation machinery, plus a probiotic, to feed the microbes your reading showed were missing.
One reading tells you more about your gut than years of trial and error ever could. That's where relief that lasts actually begins.
Your reading is built by real scientists and checked by an independent board before anything reaches you. No hype, no guesswork, just people who know guts doing the work behind the scenes, so you don't have to.
Every ingredient we use has to earn its place with real evidence. If it doesn't hold up, it doesn't go in your formula. Simple as that.

“The same symptoms can come from completely different guts. Until you actually read one, you’re treating a guess, not a person.”
“Bloating is just the headline. What matters is what your gut is actually doing underneath, and that’s exactly what a reading shows us.”
“A sensitive, reactive gut almost always has a reason. Find it, and you can stop cutting foods out one by one.”
“Two people with the exact same symptoms often need opposite formulas. The reading is what tells them apart.”
“Most gut products treat the average. Building from one person’s actual reading is a genuinely different, and more honest, approach.”
“Symptoms point you in a direction. Only a proper reading of the ecosystem tells you which pattern you’re actually dealing with.”
When you're ready to actually read your gut, here's how it goes. Nothing's charged today, you leave your details and we post your kit first.
Choose a plan and check out. No charge today, we simply validate your card and post your kit.
A two-minute sample, sealed and posted back in the same box. Send it back within 30 days, a one-time £49 fee only applies if you don't.
We read your sample and build your protocol. Your plan starts from there, posted monthly and recalibrated every cycle as your gut changes.
