UTIs are common. Living with them shouldn't be.

UTIs don’t just burn. They disrupt sex, sleep, movement, confidence, and peace of mind. Recurrence isn’t something women should be expected to live with. It’s a failure of the solutions we’ve been offered.

WHY GOOD KITTY IS DIFFERENT

Most UTI supplements look similar on the shelf. They aren't.

Soluble PACs, not just cranberry

The active compounds in cranberry are proanthocyanidins (PACs), and it’s the soluble A-type form that blocks bacteria from sticking to the bladder wall. Not all cranberry supplements deliver it in meaningful amounts.

Read more Show less

UTI Biome Shield® delivers 38mg of DMAC-verified A-type PACs, above the 36mg studied for anti-adhesion. Most cranberry supplements are made from whole-fruit or juice powder, where a 500mg capsule can contain just a few milligrams of usable PACs. PAC content is also hard to verify, so ours is DMAC-tested, the standardized method that specifically measures A-type PACs. The dose on the label is the dose in the capsule. Two products listing the same milligrams of cranberry can deliver very different amounts of what actually works.

Soluble cranberry PAC powders are dark in appearance. If it's pink, it does not contain enough active PACs for blocking E. coli.

Cranberry PACs + D-mannose: Block & Flush

PACs stop bacteria from sticking. D-mannose flushes them out. UTI Biome Shield® puts both in one daily capsule.

Bacteria grip the bladder wall using hair-like structures called fimbriae. Cranberry PACs attach to both the P-type and Type 1 fimbriae and help degrade them, giving broad, ongoing anti-adhesion with daily use. D-mannose works differently. It binds a large volume of bacteria at a single receptor and carries them out quickly, but it also leaves the body fast. That’s why a single daily dose covers everyday defense, while extra D-mannose before a known trigger delivers a heavy flush right when bacteria spike. UTI Biome Shield® combines both at meaningful doses, 38mg soluble PACs and 500mg D-mannose, so PACs hold the line daily and D-mannose flushes the spikes.

Complete UTI Protocol: Biofilm, Gut, and Bladder

Recurrence comes from what most formulas ignore. Bacteria hide inside biofilm, the gut acts as a reservoir that reseeds infection, and irritated bladder tissue stays vulnerable.

Read more Show less

Anti-adhesion is the first step, but it isn’t the whole story. Biofilms shelter bacteria from being cleared, which is why infections return. The gut microbiome can hold uropathogenic bacteria that migrate and recolonize. And a weakened bladder lining is more vulnerable to the next infection. Polyphenols help break down biofilm and feed beneficial gut bacteria, zinc supports the immune response that clears bacteria, and Vitamin D3 helps strengthen the bladder wall. Together they build a more resilient urinary environment over time, the part one-mechanism supplements leave unaddressed.

Good Kitty = Great Life! I’ve struggled with recurrent UTIs since I was 14, sometimes getting them every two weeks. Since finding Good Kitty, I haven’t had another UTI. It’s given me back the comfort, confidence, and normalcy I thought I’d lost. Thank you, Meg², for making life worth living again.
Ashley F.Verified Buyer 
Heaven sent! After 4 UTIs in the last 6 months and 7 in the last year, I was desperate for relief. I’d become antibiotic resistant and hopeless. So far, Good Kitty has kept me UTI-free. Thrilled to find a treatment that actually helps.
Lindsey P.Verified Buyer 
No games or empty promises here I am really pleased with this product. It’s a great way to build a preventative regime for yourself with a product and company that does what it says it will do. Try it for yourself!
