cranberry PACs vs cranberry for UTI prevention
36mg of PACs are the only scientifically proven compound to prevent Urinary Tract Infections.
Proanthocyanidins (PACs) are the active compounds in cranberries that prevent bacteria from sticking to the bladder wall. But most cranberry juice contains too little to be effective.
PAC Faqs
Not all cranberry ingredients are created equal. The science only holds up when PACs are delivered in the right type (A-type PACs) and in the right dose to stop bacteria from latching onto your bladder walls.
At Good Kitty Co, we use clinically validated PAC levels to ensure prevention, not placebo.
cranberry proanthocyanidins - PACs
No. You need a standardized 36mg PAC dose. Look at the labels. This is hidden of they don't. Pacran claims PACs but only has 2-5mg of bioavailable PACs.
Yes, especially when derived from high-quality sources.
Look for supplements with 36mg of soluble, standardized PACs. These are clinically shown to reduce UTI risk.
UTI Biome Shield Clinically proven UTI prevention with 38mg of bioavailable PACs in one pill.
Multi-action defense system powered by our exclusive PACphenol™ and BioBlocD3™, engineered to stop UTIs before they start. Unlike antibiotics that disrupt your microbiome, our physician-developed formula supports beneficial bacteria, neutralizes E. coli introduced during intimate moments, and addresses the gut reservoir of UTI-causing bacteria, one of the main root causes of recurrence.
DETAILS: Our clinically proven formula combines PACphenol™ (38mg soluble PACs and polyphenols) with BioBlocD3™ (d-mannose complexed with vitamin D3 and zinc) for complete UTI defense. Our formula doesn't just fight bacteria—prebiotics restore your microbiome's natural balance, bioactives heal damaged bladder tissue and strengthen your immune response.
- BLOCK E. coli receptor sites
- ELIMINATE biofilm
- REPAIR bladder tissue
- OPTIMZE microbiome
What Is D-Mannose?
D-Mannose is a Natural Ally Against UTIs
D-Mannose is a naturally occurring sugar that attaches to E. coli bacteria, preventing them from sticking to the bladder wall and flushing them out through urination.
Why It Works : Unlike glucose, D-Mannose is not metabolized the same way and does not spike blood sugar. Clinical studies show that it helps reduce recurrent UTIs in women.
How to Use D-Mannose for UTI Prevention
- Take daily with water
- Best absorbed on an empty stomach
- Safe for long-term use
D-Mannose Faqs
Yes, it is generally recognized as safe and well-tolerated.
Yes, but it's most effective as a prevention tool, not a treatment.
D-Mannose is not metabolized like regular sugar, so it does not raise blood glucose levels and is considered safe for people managing diabetes.*
Gold-Standard Ingredients for UTI Prevention
What Makes a Supplement Effective for UTI Prevention
Look for formulas with:
- 36mg of soluble PACs
- High bioavailability
- Zero fillers or sugar
Daily Use vs. Spot Treatment
The best results come from daily use. Prevention works over time—don’t wait for symptoms to start.
- Can I take these with antibiotics? Yes—just space them a few hours apart.
- Are there side effects? Generally no, but always consult your doctor.
Our formula includes D-Mannose, PACs, Zinc, and D3—all targeted at prevention. It's not a treatment, but it helps keep UTIs away.
UTI prevention is powerful
Prevention reduces bacterial load before it becomes an infection, saving you from antibiotics and discomfort. Prevention is taking before the symptoms ever come.
UTI Biome Shield works
Taking UTI Biome Shield as a preventative supplement blocks UTI-causing bacteria (reduces anaerobic + aerobic bacteria associated with recurrent UTIs) + balances the microbiome, while repairing the bladder wall.
can UTI prevention supplements cure a UTI?
No. If you're actively infected, see a doctor. Use antibiotics if you already have a UTI. But taking daily prevention supplements reduce your need for them over time.

UTI Biome Shild
Lactobacillus crispatus (the microbe most associated with a resilient vaginal microbiome) increased to 60.3%, shifting the microbiome toward a healthier, more stable state.
Bacteria Type Balances
Elevated anaerobic + aerobic bacteria associated with recurrent UTIs reduced + microbiome balance shifted toward predominantly beneficial Lactobacillus species.
Bacteria Load Panel
Microbial profile shows non-beneficial bacteria highly decreased and E. coli reduced to 0.0% — a clinically meaningful microbial shift.
