Bloating · gas · unpredictable digestion

Stop guessing what your gut needs.

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.

Step 1 of 3
Where does it hit you hardest?

Pick the one that fits best.

Why nothing sticks

You've probably tried everything. That's the problem.

Every fix on the shelf is a guess, built for an average gut, not yours. That's why the relief never lasts. Sound familiar?

  1. 1

    Cut something out

    Gluten, dairy, onions, coffee. The list of "maybe it's this" gets longer and your meals get smaller.

  2. 2

    Try another probiotic

    A different strain, a bigger CFU count, whatever the reviews say. No way to know if it's right for your gut.

  3. 3

    Feel better, briefly

    A good week. Maybe two. You start to think you cracked it. Hope is the expensive part.

  4. 4

    Back to square one

    The bloating returns. You never learned why, so you're guessing again, from scratch.

and you're back to the start

This is the guessing loop. A reading is how you leave it.

There's order under it

Your symptoms aren't random. They fit a pattern.

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.

  • Bloating and gas

    That bloated, gassy, over-full feeling after meals, even normal-sized ones.

  • Bloated every day

    Bloating that turns up daily, no matter how carefully you eat.

  • Sluggish and slow

    Everything moves slowly, and all that "healthy fibre" doesn't seem to help.

  • A sensitive, touchy gut

    Foods that never bothered you suddenly do. Your gut feels easily irritated.

  • Slow to bounce back

    After antibiotics, illness or travel, it takes far too long to feel normal again.

  • Drained and reactive

    Low energy, off your food, reacting to more and more. Everything feels run down.

  • Stress hits your gut

    When life gets stressful or sleep slips, your gut is the first thing to feel it.

  • In good shape

    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.

Reading your gut at species level

The way out

Stop guessing. Read your gut.

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.

Readout → protocol

Your reading becomes a protocol.

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.

  • Activate, morning protocol Morning

    Activate

    With your first meal

    The morning foundation, built from what your reading found you're short on, to start the day steady.

  • Restore, evening protocol Evening

    Restore

    Before bed

    A calmer, overnight layer, added only when your reading calls for it. Nothing here by default.

  • Nourish, precision prebiotic powder Anytime

    Nourish

    Once a day

    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.

Stop guessing.
Start reading.

One reading tells you more about your gut than years of trial and error ever could. That's where relief that lasts actually begins.

The nb1 team at work

Real science, minus the white coats

Serious about your gut. Not clinical about you.

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.

  • Built by scientists Designed by our own researchers, not marketers.
  • Checked independently An outside board signs off before it reaches you.
  • Evidence, not hype Every ingredient earns its place, or it's left out.

The board behind your reading

Real scientists design and check every formula, including two independent academics with no stake in the company. Meet the full board →

    “A sensitive, reactive gut almost always has a reason. Find it, and you can stop cutting foods out one by one.”

    “Symptoms point you in a direction. Only a proper reading of the ecosystem tells you which pattern you’re actually dealing with.”

How it works

From symptoms to a real answer. No more guessing.

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.

What it costs to read your gut

Two ways to read your gut.

Both start the same way: read your gut, build your formula, recalibrate every cycle. The difference is how deep the reading goes.

Your gut, decoded

Stop guessing. Read your gut.

A reading shows what's actually driving your symptoms, then we build a formula from it, dosed to your gut. Nothing's charged until your formula is made.
