how it works
Stop a UTI before it starts.
UTI Biome Shield™ is a targeted blend of clinically studied ingredients that block, flush, and rebalance, addressing UTIs at the source.
Block Bad Bacteria
38mg of 100% soluble cranberry PACs bind to P-type and Type
Instant Flush
D-mannose is absorbed within 30 minutes and flushes bacteria already attached to the bladder lining for rapid clearance.
Bladder Defense System
Prebiotic and immune support trio that breaks down biofilm, strengthens bladder tissue, calms inflammation, and feeds beneficial bacteria.
WHAT THE DOCTORS ARE SAYING
Doctor Formulated. Doctor Recommended.
"Only bioavailable PACs prevent UTIs; Good Kitty is setting a new standard in UTI prevention."
"UTI Biome Shield is the most advanced UTI solutions I've encountered in clinical practice."
"UTI Biome Shield is an easy prevention solution for our patients."
REAL RESULTS
From women who'd tried everything else
Verified customer reviews of UTI Biome Shield.
Read all reviewsI had been on prophylactic antibiotics for almost two years before my doctor suggested I try this. Six months in and not a single UTI.
I've tried every cranberry pill on the market. This is the first one that actually feels different and my recurring issues finally stopped.
My urogynecologist recommended it alongside my existing care plan. Easy to take, no weird side effects, and I feel like I finally have control.
WHY GOOD KITTY
UTI prevention only works when every pathway is covered
Most supplements rely on one mechanism. This is a complete protocol.

Most UTI supplements address one step.
UTI Biome Shield™ covers the full cycle.
Here's what it would actually cost to build your own UTI Biome Shield™
We did the math. If you tried to source the exact patented ingredients Good Kitty uses, at the same clinical doses.
You'd be taking 10+ capsules a day
Clinical doses of cranberry PAC, d-mannose, D3, zinc, and polyphenols add up to a fistful of pills across multiple bottles. Biome Shield delivers all five in two small capsules a day.
Clinical-grade ingredients are hard to source
DMAC-verified cranberry extract, pharmaceutical-grade d-mannose, and lichen-derived D3 aren't on your local shelf. Biome Shield uses the exact versions studied in the research.
Unpatented, untested combinations are less effective
A stack of loose supplements isn't the same as a physician-formulated protocol. Our patent-pending PACphenol and BioBlocD3 complexes are built to work together.
the hard way
Cost to source actives separately
- 10+ capsules daily across 5 bottles

- KMKerri M.Verified BuyerReviewingUTI Biome Shield® Compostable Refill PacketRated 5 out of 5 starsWhat a find!
I have been using good kitty for a little over 2 1/2 months. I have not had a UTI which I usually am prone to get. Super easy to take and the jar on the counter is pretty so don’t mind leaving it out. This stuff works amazing.
- ADAndrea D.Verified BuyerReviewingUTI Biome Shield® Starter KitRated 5 out of 5 starsDefinitely going to continue using this product!
I struggle with chronic UTIs and often have to drink nasty supplements to keep symptoms at bay but these pills come in a lovely reusable gold bottle that I can keep bedside and the vile that holds 2 pills helps me remember to take them when I’m out.
- AEAnna E.Verified BuyerReviewingUTI Biome Shield® Starter KitRated 5 out of 5 starsUTI free since finding this product
I have suffered from UTI’s brought on by sex since I became sexually active. And after taking antibiotics three times in the last four months despite following all of the prevention rules (pee after sex, stay hydrated, maintain good hygiene down there with just soap and water), I was fed up. I feel lucky to have come across Good Kitty. Since taking it, I have been UTI free and actually want to be intimate with my partner again.
- DBDiane B.Verified BuyerReviewingUTI Biome Shield® Starter KitRated 5 out of 5 starsBest UTI Remedy I have tried
After trying several remedies for UTIs, and many antibiotics, I tried good Kitty. I've been taking it religiously as directed, for several months, I am symptom and UTI free. Almost seems magic!
- MSMaryam S.Verified BuyerReviewingUTI Biome Shield® Starter KitRated 5 out of 5 starsSeems to be working!
Fingers crossed I’ve been taking these for a few months now and it feels so much better “down there”! It’s still new but I’ll keep taking them since I always get UTI after or during menstruation. I’m perimenopausal and it’s been crazy with the UTI’s and after many failed attempts with other companies, I’m sticking with @goodkittyco! Also, love the jar system as it’s not only pretty to look at, but a great reminder to take these capsules daily.
