PACphenol™ & BioBlocD3™
"UTI Biome Shield represents a significant advancement in urinary tract health. For patients seeking evidence-based, non-antibiotic approaches to UTI prevention, this is the most advanced solution I've encountered in clinical practice."
"Only bioavailable PACs prevent UTIs. Most cranberry supplements don't contain enough of the active compound to prevent UTIs. Good Kitty has the highest and combines it with d-mannose which is setting a new standard in UTI prevention."
"Your gut remains stubbornly colonized with these bad bladder bugs and only bioavailable cranberry products appear to reduce the recurrence of bladder infections by about 35%. Not as effective as antibiotics, but cranberries don’t foster antibiotic resistance, and have fewer side effects."
"At Tia Health, we provide affirming primary care for women, including gynecological services, primary care, procedures, and holistic care. We offer online treatment for UTIs, including diagnosis, treatment recommendations, and prescription management. UTI Biome Shield is an easy prevention solution for our patients."
ADVANCED UTI PROTECTION
What is BioBlocD3?
While basic d-mannose supplements offer partial benefits, Good Kitty's UTI Biome Shield advanced formulation with BioblocD3 technology represents the next generation of urinary tract protection.
ADVANCED UTI PROTECTION
What is PACphenol?
A patented double extraction yields the highest concentration of bioavailable proanthocyanidins (PACs) you can get. PACs play an integral role in bacterial anti-adhesion and UTI prevention.

- GRGigi R.Verified BuyerReviewingUTI Biome Shield™Rated 5 out of 5 starsFinally, something that actually works (and looks cute doing it)
I’ve struggled with recurrent UTIs for years. After trying every “natural” remedy, prescription, and old wives’ tale (looking at you, cranberry juice), I finally found Good Kitty Co and their UTI Biome Shield—and I’m never going back.
First off, the science is legit. You can tell this wasn’t slapped together in a marketing meeting—it’s formulated by actual doctors with PACs, d-mannose, zinc, and D3. Since I started taking it daily (and especially before sex and I take 3 cuz that’s me), I haven’t had a single UTI. Not one. That’s wild for me.
Second: the packaging is gorgeous. Like, actually display-worthy. The gold canister looks more like a luxe candle than a supplement, and the refillable system makes me feel like I’m doing something good for the planet and my body. The pill is even purple. I mean… come on.
And the best part? The brand just gets it. It’s for women who are done with shame and silence around their sexual health. I’ve never felt more seen, and honestly, I wish I’d had this in my 20s.
If you’re prone to UTIs—do yourself a favor and try this. Your bladder (and your sex life) will thank you.
GOG O O D K I T TY c oWow. This review gave us chills 💖 Thank you for saying it all so perfectly — the science, the design, and the fact that women deserve to feel seen (and sexy) while taking care of their health. We know how many disappointing “remedies” are out there, so hearing that UTI Biome Shield has actually kept you clear is everything we hoped for when we created it. And yes… the purple pill + gold canister? That’s the vibe 😸✨ We’re so grateful you’re part of the Good Kitty community — here’s to no more cranberry myths, no more shame, and lots more freedom.

- MMichelleVerified ReviewerReviewingUTI Biome Shield™Rated 5 out of 5 starsA must addition to UTI protocol
After years of UTIs and a particularly rough string of a UTI a month for 5 months I finally found the UTI biome shield. I am feeling very protected and reassured in my journey and have not had any flairs or new infections.
