GutGutGoose runs an at-home gut microbiome test and compounds a personalized probiotic matched to the customer's own sequencing results.
GutGutGoose sells two personalized probiotic subscription tiers, both compounded from the customer's own gut sequencing. The STARTER tier delivers a once-daily capsule set with up to four strains at 93 US dollars per month across three payments, and the COMPLETE tier carries up to twelve strains at 183 US dollars per month.
Each tier includes a retest kit so the next ninety-day cycle is built from what the previous cycle changed, and both are covered by a 180-day money-back guarantee with free shipping in the United States.
GutGutGoose operates in a personalized probiotics market that Business News Australia, citing IMARC, sizes for Australia alone at 2 to 3.7 billion US dollars by 2034, which places the company's two-country launch footprint inside one of the larger national segments of the category. The company's competitive set is the broader at-home microbiome testing and compounded probiotic field, where rivals sell either sequencing or generic formulations rather than both in one loop.
Its model converts every paying customer into a repeated measurement, so the same revenue line also builds a proprietary longitudinal dataset. Whether that dataset becomes defensible depends on retention through each 90-day retest cycle.
GutGutGoose's stated advantage over generic probiotics is colonization, not strain count. The company reports that its matched formulations achieved an 84.7 percent colonization rate in one cohort and 76.7 percent in another, against the low single-digit rates it attributes to off-the-shelf supplements.
Its catalogue is sixteen strains, all licensed by Australia's Therapeutic Goods Administration and covered by a provisional patent, and it has run two clinical studies of its own to date. Compounding happens in a TGA-licensed Queensland facility, so formulation and retesting sit inside one closed loop that the company says no off-the-shelf supplement can reproduce.
GutGutGoose prices both personalized probiotic tiers as 90-day subscription cycles rather than one-off test kits. The STARTER tier is 93 US dollars per month across three payments for up to four strains, and the COMPLETE tier is 183 US dollars per month for up to twelve strains plus a specialist review of the results.
Both tiers include the retest kit in the price and carry a 180-day money-back guarantee, with free shipping in the United States. The company sells only in the United States and Australia and routes customers elsewhere onto a waitlist.
