Your protocol is the live cultures, the fibres that feed them and the supplement layer your reading called for — each one dosed to your gut. Nothing is manufactured before we have read you.
Every formula reviewed by our seven-person science board, analysed in EU labs.
One sample, collected at home. Everything after that is ours.
That single charge unlocks your report and releases your first delivery. Never before.
A sample in private, sent back with the prepaid return, plus a short intake form: your diet, your symptoms, what you already take.
Shotgun sequencing in EU labs reads every organism at species level. You get the full report.
Built from that report and nothing else, then delivered presorted. It tops up monthly.
A small stool sample. A few tiny amounts into the tube, nothing more. Private, and done in minutes.
Seal it, and send it back with the prepaid return included in your kit. Everything you need is in the box, and a replacement kit is free if anything goes wrong.
One finger prick, and a single drop of blood into each circle on the two collection cards. They go into the envelope, and back in the same return bag as everything else.
No needles, no clinic, no appointment. The panel tells us what actually reached you, so your doses land on measured levels rather than on symptoms.
Sequencing produces the numbers. Seven specialists review them against your intake form and turn the two into a decision — the people who read your sample and build from it, plus two senior microbiome scientists who check the method from outside, with no stake in nb1. No formula is made until one of them signs it off.
Every species scored across the eight patterns, against a reference set of 8,069 guts.
The answers you gave us: what you already take, your diet and lifestyle, your symptoms, your goals, and anything a clinician should know.
You get the full reading in plain language, and the formula it decides. Nothing is made before that signature.
Built in three parts, each a small set of units. Only the ingredients your reading calls for go in, each dosed to your gut. Nothing is a default.

Everything is pre-sorted before it ships. No juggling bottles, no pill organiser, no counting. What is left is yours: the commitment to show up.
Taken with your first meal.
Taken before bed.
Whenever suits your day.
This was the drawer. This is the whole thing now.
Your whole day arrives already divided into morning and evening packs. No pill organiser, nothing to count, nothing to measure out.
Tear off the days you need and go. Packs slip into a bag or pocket, so a weekend or a full month packs flat in seconds.
Your next month arrives before you finish this one. No reordering, no gaps to plan around, no running out mid-week.
“They've made taking supplements much easier for me, since everything is already organised by them into morning and evening doses.”
Every plan starts with the same gut reading, and the formula built from it. Advanced then adds three things, and they work as one loop: we measure again, we rebuild from the new numbers, and we add a blood panel so the doses land on measured levels rather than on how you say you feel.
We re-read your gut and your blood on the same methods, so the new numbers are comparable to the old ones rather than a fresh opinion.
Your formula is not topped up from the last one. It is built again from the new reading, so strains and doses follow where your gut has actually got to.
Your gut read says what your microbes can do. A blood panel says what actually reached you, so doses land on measured levels instead of on symptoms.
You can start on Core and move up at any cycle boundary. Your existing reading carries over, so nothing is re-collected and nothing restarts.
Compare Core and Advanced →Your kit ships first; your formula is produced after your analysis, never before.
We read your gut, and build your formula from it.

Gut and blood. Your formula rebuilds every cycle.
Four months is the minimum cycle, the window biology needs to shift.
Charged only when your formula is made, never before your analysis completes.
The minimum window biology needs to shift, not a contract trick.
The analysis is the product. It is in your subscription, not an add-on.
