The only probiotics matched to your missing strains
Most people try 4-5 brands before giving up. You're about to try your last one - the one made for your gut.
Your gut influences
Everything.
3pm crashes.
Bathroom anxiety.
Same problem.
Generic probiotics failed because your gut destroys foreign bacteria on sight. You need the right strains at doses that actually colonise.
That 3pm exhaustion? Same source as your bathroom anxiety
-imbalanced gut bacteria producing inflammatory compounds. Your 40s are being written by your microbiome right now.
Colonisation resistance means 99% of probiotic strains die in your gut within 48 hours. You need 50 billion CFUs minimum to establish new colonies. Most brands ship 5 billion. You've been underdosing by 10x.
We test your bacteria, deliver therapeutic doses, then test again to prove colonisation. No other company verifies their probiotics actually survived. We show you the data.
Custom probiotics for gut health test and best probiotic for bloating with personalized options available.
The Problem

Every store bought probiotic contains the same few bacteria. For everyone.

Your completely unique gut, their completely unique gut - same exact bottle. The math never made sense.

You know what happened next.
Nothing. Or worse - you felt more bloated, more exhausted. Because those ten bacteria? They were feeding what you already had too much of. Strengthening the wrong populations. Like watering weeds hoping flowers would grow. Your gut needed completely different bacteria. It always did.
Taking the same probiotic as everyone else is like wearing someone else's prescription glasses and wondering why you still can't see.
We've analyzed thousands of microbiomes.

No two matched. Ever.

Meanwhile, every month on the wrong bacteria, your exhaustion compounds. Your bloating entrenches. That energy at 3pm? That morning without negotiation? That freedom from gut planning? Only happens when you get YOUR specific missing bacteria. We can tell you exactly which of 300+ possible bacteria you need.
From one simple test.
At home.

Getting Back to Normal

What 71% of people experience by week 16 (according to published research)

"I eat lunch and still have energy at 3pm"
Published research shows digestive comfort supports sustained energy levels. You're not crashing at your desk anymore. You stopped needing that emergency sweet snack. The food coma that hijacked your afternoon - gone.

You have the energy to volunteer for afternoon meetings now. That heavy, "I want to lie down" feeling after eating vanishes. Studies link digestive optimisation to nutrient absorption and energy maintenance.1

Typically emerges by weeks 8-10. No special effort required.*
"I'm not the person who crashes anymore"
Clinical research demonstrates 63% of participants achieve significant symptom improvement by week 8.2 You're still contributing in 4pm meetings. Actually hearing what people say after 2pm. That person who lived on coffee and willpower - that's not you now.

You stopped declining lunch invitations. Your partner notices you're really, actually present for evening conversations. Published studies confirm sustained digestive comfort throughout the day.2

Typically weeks 6-12. Happens while you're living, not trying.*
"Mornings don't require negotiation anymore"
Meta-analysis shows personalised probiotics achieve 44% response rate versus 22% for generic formulations, that's a 2x difference.3 You wake up and just... start your day. No bathroom mapping. Morning is just morning again.

You're scheduling early meetings without panic or worries. Your family stopped tiptoeing around you before 10am. Research confirms improved morning digestive comfort.3

Builds progressively weeks 10-16. Nothing you need to do.*
"I'm not the first one sick anymore"
Research confirms 70% of immune cells reside in the gut.4 The office cold makes rounds - you keep working. Your kids bring home everything - you're still standing. Published studies demonstrate probiotic support for immune functions.5

You stopped hoarding sick days. Travel doesn't automatically mean travel recovery time. Clinical evidence links gut health to immune system support.5

Strengthens naturally by weeks 12-16. Building protection naturally.*
"I forgot I was someone with 'gut issues'"
Research shows 71% of participants maintain improvements at 16 weeks and beyond.1 You're not managing anymore. You're forgetting. Forgetting which foods were "dangerous." Forgetting your bathroom strategies. (Although you never forget diet is critical, and to listen to advice from your medical professionals).

Friends stop asking "can you eat there?" Your emergency kit gathers dust. Published studies demonstrate sustained probiotic benefits with continued use.6

This deepens over months. Supporting long-term digestive wellness.*

mathematically proven wellbeing

You're wasting $600-1,200 yearly on probiotics that never actually colonise.

Research shows 77% of generic strains fail to establish. Our approach achieves 2.3x superior colonization- verified through DNA.
Step 1: Test Your Unique Microbiome
Your kit arrives in 2-10 days. We analyse 300+ bacterial strains in YOUR gut- not the 10 or so species regular probiotics providers just guess are there. This precision feeds computational modelling that predicts which probiotics will actually colonise YOUR specific ecosystem. Labs charge $500+ for this sequencing, we take a loss to include the best testing possible in your subscription.
Step 2: Receive Your Pharmaceutical-Grade Formula
Your personalised formula arrives fresh from our TGA-licensed facilities located in Queensland's sunshine coast- manufactured to medicine standards, not supplement rules. Each batch is precision compounded within days. Your 8-20 strains at therapeutic doses, verified through TGA licensed laboratory testing.
Step 3: Verify & Evolve Quarterly
When you take store bought probiotics you take them and hope they work- that's not the case here. GutGutGoose is the only probiotic in the world that uses semi-annual DNA proof showing exactly which strains became permanent residents versus temporary tourists. We track YOUR bacterial changes and evolve your formula based on what actually worked.

FAQ

Common
questions

How does gutgutgoose work?

We analyse your microbiome from a simple at-home stool test, then create an advanced model of your gut, we give you deep insights on how and why your gut works and then select probiotic strains to match your gut profile and goals.

Your tailored capsules are compounded in TGA-licensed facilities in Australia and delivered monthly. Retesting every 6 months improves our model of your gut letting you understand your health over time and helping us refine your formula as your gut changes.

How does the AI actually choose my formula?

At just 50 strains analysed there are more than 1 quadrillion (1,000,000,000,000,000) potential combinations.  A human doctor can't solve for this, in fact, it would take a person 31.7 million years just to count that high.

Instead, GutGutGoose uses a Hybrid Mechanistic-AI Framework to mathematically solve for your gut.

1. We use your gut test results to see which of 7,302 strains we have modelled are growing in your gut, then we gather data to create a model of your gut that's as true to life as possible - from bacteria, all the way to your diet and habits.
‍
2. We can then use this data to create a model. We then run digital experiments till we select the perfect probiotic combination. We use physics and advanced algorithms to bridge the massive mathematical burden to create simulations of how bacteria compete for resources in your body.
‍
3. We then only compound bacteria mathematically compounded to survive and thrive. This has been shown to be at least 130% more effective than store bought probiotics.

The subscription is $166 a month. What exactly am I paying for?

People waste money on store bought probioitcs that don't colonise, you're paying to never do that again. No other company verifies their probiotics actually survived. We show you the data.

‍Our cost reflects 3 clinical grade processes.

1. Metagenomic DNA sequencing ($500 value), this is included in your subscription and repeated every 6 months.  We analyse 300+ strains in your gut using deep-read technology through Australian based partner labs like the Australian Genome Research Facility.

2. TGA-Licenced compounding ($180 value), Your formula is made to order in a TGA-Licenced facility in the Sunshine Coast to medicine standards, not loose supplement rules.

3. Quarterly verification and model training (first in kind technology), We retest every 6 months, as our models get trained on your gut they become more and more accurate.

What is the 180 day money back guarantee?

Take GutGutGoose for 180 days, we'll retest after that time- if the tests show no colonisation (meaning bacteria didn't stay) and you didn't feel any effects from them passing through then we'll refund you in full. You keep your data and insights regardless. No other company verifies their probiotics actually survived. We show you the data and believe that if the science doesn't work - you shouldn't pay.

When will I feel something?

Everyone’s body is different, and the benefits you may ‘feel’ from your custom probiotic (ease of bloating, more regular bowel movements) are often just the most visceral ones.

Your initial gut formula is designed to introduce beneficial probiotic strains to your system. Based on your unique gut health environment, some of these bacterial strains may flourish while others may shrink; this is a normal and expected part of personalising your health solutions. The important and wonderful part of our long-term retesting is that over time and with each new sample, we can refine your probiotic mix. This allows our team to improve your custom probiotics, ensuring that as your gut microbes shift, your formula gets better and more effective at supporting your digestive health and immune system.

You'll be able to track this through the raw and analysed gut testing data we provide you with every 3-6 months!

Can I take with other supplements? What about other medications?

Yes, but interactions can occur. For instance, if you take antibiotics your gut's going to change a lot from what we've modeled. Check the label and speak with your health professional if unsure. We’ll share your ingredient list to make that easier.

What about data privacy?

Your data is encrypted and stored securely in Australia. The entire gut gut goose process is handled in Australia, nothing goes overseas. Simple as. Also please share your test results with your healthcare professionals, sharing is caring!

See results in 180 days or full refund- because if probiotics don't work, you shouldn't pay.
