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 FDA-registered facilities and delivered monthly across the US and AU. Retesting every 90 days improves our model of your gut, helps you understand your health over time, and lets us refine your formula as your gut changes.

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 modeled 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.

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 90 days. We analyze 300+ strains in your gut using deep-read technology through US-based partner labs.

2. FDA-registered compounding ($180 value), Your formula is made to order in an FDA-registered facility to rigorous quality standards, not loose supplement rules.

3. Verification every 90 days and model training (first-in-kind technology), We retest every 90 days. As our models train on your gut, they become more and more accurate.

The test is the starting point. Your membership also includes the detailed reports, personalized interpretation, microbiome-profile-informed formulation, mathematical modeling used in the formulation process, and the thread that connects one evidence point to the next. We assign a stated dollar value only to testing, so the stack stays honest.

Another report beside your baseline—one more evidence point that may inform review or adjustment. Its job is to give the next decision more context, not to pretend a single measurement proves cause.

No. They cover laboratory testing only—not the full journey from checkout through report, interpretation, formulation, or fulfillment. The comparison is still meaningful: about three weeks on Regular and about one week on Executive.

Every plan includes the same core personalized system. What changes is the testing cadence, laboratory speed, level of service, terms, and way you join.

Pricing note

$500 is GutGutGoose’s stated value per test—not a verified standalone retail price, savings claim, or total membership value. The 12-month totals are arithmetic at the monthly rate, not annual commitments.

Take GutGutGoose for 90 days. Then we retest. If your strains did not colonize, and you followed the plan, we refund you. You keep your data either way.

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 personalizing 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 analyzed gut testing data we provide every 90 days!

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.
