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.
How it works
You poop in a cup. Scientists map every bacterium, use a supercomputer to build a virtual copy of your gut, run millions of simulations, then compound probiotics engineered to actually work inside you.
Retests are included every 3-6 months and if your testing shows no colonisation - you get all your money back. With each retest our probiotic gets better and better fitted to your gut.
The problem
Store-bought probiotics are built for everyone. Your gut isn't.
One bottle can't fit every microbiome. We test first, then match strains to your gut.
Generic probiotics can do nothing—or make bloating worse—when they feed the wrong populations. GutGutGoose starts with your data, not a guess.
Generic probiotics are like someone else's prescription glasses: close isn't enough.
No two microbiomes match. We identify which bacteria your gut is missing and build around that from one at-home test.

Personalised, verified probiotics
Stop guessing. Test your gut, then build for it.
DNA sequencing, TGA-licensed compounding, and 180-day verification in one monthly plan.
Step 1: Test your microbiome
Your kit arrives at home. We sequence 300+ bacterial strains and use the data to model what your gut needs.
Step 2: Receive your matched formula
Your formula is compounded fresh in TGA-licensed facilities with therapeutic-dose strains selected for your ecosystem.
Step 3: Verify and refine every 6 months
We retest every 6 months, show what colonised, and refine your formula as your microbiome changes.
GutGutGoose's vision is to one day decode early disease signals in your microbiome using breakthrough probiotic technology. We're working towards a future where we can predict chronic illnesses decades before symptoms appear.
"There is hardly any condition that isn't significantly affected by our gut biome. Gutgutgoose is offering a revolutionary approach to re-balancing the gut by blending cutting edge science, technology and artificial intelligence.

"The TGA-licensed compounding and published colonisation rates address the biggest problem in probiotics: most strains don't survive. These ones are selected to thrive in each specific gut ecosystem."

FAQ
Common questions
How does gutgutgoose work?
We analyze your microbiome from a simple at-home stool test. Then we build a model of your gut and choose probiotic strains that 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?
Your gut has too many strain combinations for guesswork. We use your test data, diet, and goals to model your gut and choose strains most likely to colonize.
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 $199 a month. What exactly am I paying for?
People waste money on store-bought probiotics that do not colonize. You are paying to stop guessing. We test, build, and show you the data. 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. Then we retest. If your strains did not colonize, and you followed the plan, we refund you. You keep your data either way.
When will I feel something?
Everyone is different. The first changes people tend to notice are less bloating, more regular bowel movements, steadier energy, or clearer thinking.
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 modelled. 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. Nothing goes overseas. You can share your results with your healthcare team whenever you want.
