Every supplement you've tried promised results "soon" and never said when. This one comes with a timeline built from your own gut reading, mapped across your first full cycle, and a reading at the end to show what actually moved. Here's what the weeks really look like.
Built from your reading, measured against it every cycle. A timeline, not a promise.
Every supplement you've tried worked the same way: take it, hope, wait for a payoff nobody ever defined, and quit when nothing obvious happened. With no timeline and nothing to measure, you were set up to give up.
A probiotic, a fibre, whatever the reviews rated. No real idea what it's doing, or when it's meant to work.
A week? A month? Nobody said. So you watch for a change with nothing to measure it against.
Maybe a little better, maybe not. With no marker, you can't tell a real shift from a good day.
You stop before anything could have landed. Back to square one, still guessing.
A protocol should tell you when. And prove it when the time comes.
Not a contractual lock. The minimum window in which real biological change can be measured, tracked month by month.
Probiotic strains begin colonising. You may notice small shifts in digestion, normal as your gut adjusts.
SCFA production rebuilds as fibre supply stabilises. Energy and sleep often respond first.
Team composition shifts measurably. Skin and immune markers tend to follow.
On Advanced, the same pipeline runs again, now with your first blood biomarker panel layered in alongside it. Your formula recalibrates against everything that shifted, in your gut and your blood. On Core, add a retest whenever you want to see your change.
Retest your gut and see exactly what moved. The same markers, re-measured before and after. One number, objectively re-scored.
The score is what we measure. How it feels is what members tell us, self-reported alongside each retest, not a lab result.
Sleep is self-reported and logged alongside your gut score at each retest. As fibre-fed species recover early in a cycle, sleep and energy tend to be among the first signals people notice shifting.
Energy is one of the self-reported markers tracked against your gut score. In the early weeks, as bifidobacteria respond and fermentation picks back up, daytime energy is often where people report the earliest change.
Bloating is the most direct read on how the gut is running day to day. As an ecosystem moves from a protein- or mucus-driven state back toward a fibre-fed one, digestive comfort is usually where change shows up first and most clearly.
Stress is self-reported alongside each retest. The gut and the systems governing stress are in constant chemical exchange, so it tends to be a slower-moving marker, usually consolidating in the back half of a cycle rather than the first weeks.
An example retest, ~4 months in. Individual responses vary; your own retest measures your markers, before and after.
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.
A protocol built from your own reading, with a timeline you can hold us to, and a second reading to prove it moved.
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.

“When a formula is built from your actual gut, you’re not hoping something works, you’re giving it exactly what the biology asked for. That’s what makes the difference show up.”
“The data tells us precisely which inputs will move your gut and which won’t. That’s the difference between a formula that does something and one that just looks good on a label.”
“Give a gut what it’s genuinely missing and it settles, becomes more resilient. That’s the outcome we build toward, not just a shorter ingredient list.”
“Two people can need opposite formulas to reach the same result. Reading each gut is how we get both of them there, and how we can measure it actually worked.”
“Building from one person’s reading produces a formula that genuinely fits them. That’s a more honest, and more effective, place to start than the average.”
“Match the inputs to a gut’s real ecosystem and you change what that ecosystem produces. That’s where the meaningful results come from.”
When you're ready to start the clock, 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.
Not sure yet? Compare Core and Advanced side by side first, no card needed.
See the plans →Both start the same way: read your gut, build your formula, recalibrate every cycle. The difference is how deep the reading goes.
We read your gut, and build your formula from it.
Gut and blood. Your formula rebuilds every cycle.
4-month minimum, biology takes that long to shift. Prefer no commitment? The month-to-month option is £109/mo. Compare in detail →
We read your gut and build your formula from it, then show you what to expect, when, and how we prove it moved. There's a four-month minimum, because biology takes that long to shift.
