During perimenopause, I got stuck in a UTI spiral. I've been taking Good Kitty for several months and NO UTIs!
Recurrent UTI Savior
I am SO grateful this product exists! I will be recommending to anyone with the same problem.
Amazing product
This product has made a huge difference for me. I would highly recommend it to anyone struggling with UTIs.
When to Take It
Timing and dosing matter
Simple daily support, with an extra dose before intimacy.
WHY GOOD KITTY
Recurrent UTIs need more than a one-step solution.
Most UTI supplements target a single mechanism. UTI Biome Shield® takes a multi-pathway approach to recurrent UTI prevention, supporting bacterial defense, biofilm disruption, and urinary tract health.

UTI Biome Shield® FAQs
UTI Biome Shield® is designed for anyone who experiences recurrent UTIs or wants to proactively support their urinary tract health. Take one capsule a day with water. On days you have sex, take two more capsules 30 to 60 minutes before, then drink a glass of water and pee afterward.
UTI Biome Shield® is not intended for children. If you're pregnant, breastfeeding, managing a medical condition or taking prescription medication, talk to your clinician before starting.
To maintain a healthy urinary tract: Take 1 capsule daily with water about the same time every day. For known triggers (such as travel, stress, lack of hydration, or inability to visit the bathroom ) or if you have early warning signs, take 2 capsules daily as needed, then return to one daily.
UTIs from sex: Because sex often results in bacteria in the urethra, take 2 additional capsules of UTI Biome Shield® 30-60 minutes before sex.
Remember: UTI Biome Shield® won’t treat or cure a UTI, but it can help maintain a healthy urinary tract to avoid future UTIs. If your doctor confirms an active UTI, take the full course of your antibiotic. You can continue taking UTI Biome Shield® daily alongside it.
One UTI Biome Shield® refill packet contains 60 capsules. This could last you anywhere between 30-60 days, depending on how often you're getting lucky.
If you currently have a UTI, please consult with your healthcare provider for appropriate treatment. UTI Biome Shield® is designed for prevention and maintenance.
With, never instead. A confirmed urinary tract infection usually needs antibiotic treatment.
You can take UTI Biome Shield® with your antibiotic as extra support against UTI-causing bacteria until the infection clears, and then continue taking UTI Biome Shield® once daily to maintain a healthy urinary tract. We recommend taking UTI Biome Shield® two hours before or after your antibiotic dosing.
Please note: taking antibiotics every day may not be the best plan for UTI prevention. Bacteria can become resistant to antibiotics, and antibiotics come with side effects like stomach upset, allergic reactions and yeast infections.
No, UTI Biome Shield® is a dietary supplement and does not require a prescription.
No supplement can guarantee you’ll never get a UTI. If you get one while taking UTI Biome Shield®, contact your healthcare provider and ask for a urine culture, which identifies the bacteria and guides treatment. If infections keep coming back, ask your provider whether you need further evaluation or other prevention options.
UTI Biome Shield® is a doctor-formulated, patent-pending urinary health supplement. Each capsule has over 36 mg of soluble A-type PACs, measured by the BL-DMAC method, which is the amount used in clinical cranberry research.
The PACs come only from cranberry juice extract, not the skins and stems used in many cranberry supplements. That means they’re 100% soluble, the only form shown to block bacteria from sticking, at a 30% PAC concentration compared with 1% to 18% in many other cranberry ingredients.
UTI Biome Shield® also contains D-mannose, vitamin D3 and zinc, ingredients studied for different mechanisms, not just the single pathway cranberry targets.
Most people begin to notice benefits within 2-4 weeks of consistent daily use.
We recommend 3-6 months of consistent use to see results.
UTI Biome Shield® is generally well-tolerated. Some people may experience mild digestive changes as their microbiome adjusts.
During menopause, lower estrogen levels can thin the urinary tract lining and alter vaginal pH, making it easier for UTI-causing bacteria to grow and stick, increasing your risk for infection. While vaginal estrogen is a first-line therapy for recurrent UTIs caused by hormonal shifts, UTI Biome Shield® is a great addition to help maintain good postmenopausal urinary health.
Interstitial cystitis is a chronic bladder condition, not an infection, and UTI Biome Shield® is not a treatment for IC.
Some people with IC are sensitive to acidic foods and drinks. UTI Biome Shield® has about the same acidity as a cup of coffee or cola, so if those bother your bladder, start slowly or check with your doctor first. Talk to your doctor for proper IC treatment.
Yes! You can safely take UTI supplements like UTI Biome Shield® with probiotics for added urinary tract support. Many healthcare professionals recommend pairing UTI Biome Shield® with a good probiotic that supports the gut, urinary tract, and vaginal microbiomes—a key tool in maintaining overall pelvic health.
UTI Biome Shield® hasn’t been studied in pregnancy or breastfeeding, so talk to your OB or midwife before taking UTI Biome Shield®. If you’re pregnant and have UTI symptoms, contact your provider the same day. UTIs during pregnancy need prompt medical treatment and can’t be managed with a supplement.
If you take prescription medication, check with your clinician or pharmacist before starting UTI Biome Shield®. Cranberry may interact with blood thinners such as warfarin, so let your doctor know if you take one.
If you’re on an antibiotic, take UTI Biome Shield® two hours before or after each antibiotic dose.
