UTI Biome Shield™ Prevention Actives
- Protection against UTI-causing bacteria, active within 4-6 hours, lasting 12 hours
- Bind and block TWO distinct receptors on bacterial fimbriae (arms), so that bacteria can't attach and are flushed out of the body.
- They directly alter makeup of the gut and urogenital biome by feeding beneficial bacteria, crowding out UTI-causing bugs and down regulating the virulence factors that help them cause infections.
**Per the FDA, consuming 500 mg each day of cranberry dietary supplement may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women.
- Provides early protection against UTI-causing bacteria, active 30 minutes post-ingestion, lasting 6 hours
- binds to Type 1 E. coli receptor arms, allowing them to be flushed out of the body.
- Prebiotic support healthy gut bacteria.
- Urothelial repair
- Boosting immune regulation
38mg per BL-DMAC verification A-type soluble PACs from 100% cranberry juice.
The highest concentration of bioavailable proanthocyanidins (PACs) you can get. Patented double extraction of the active compounds in cranberry juice and whole fruit means PACs are 100% bioavailable.
PACs play an integral role in bacterial anti-adhesion and UTI prevention, binding to TWO distinct receptors on bacterial fimbriae (arms), so that bacteria can't attach and are flushed out of the body.
Naturally occurring sugar present in many fruits and vegetables and is an important part of human metabolism, bacterial anti-adhesion and urinary tract health.
D-Mannose binds to Type 1 E. coli receptor arms, allowing them to be flushed out of the body. There is new evidence that it acts as a prebiotic in the gut to support healthy bacteria.
Lichens are a rare, plant based source of vitamin D3, the biologically active form of cholecalciferol. Vitamin D3 fortifies the bladder wall barrier by promoting cellular tight junctions, urothelial repair, immune regulation and preventing UTIs. It has a regulatory role in acute and recurrent infections especially in women of reproductive age.
Zinc deficiency has been linked to recurrent UTIs. Cells in our immune system known as macrophages deploy zinc to clear bacterial infections. Taking micronutrient supplements such as zinc, may assist in preventing UTIs.
UTI Biome Shield contains the full complement of anti-oxidant and anti-inflammatory polyphenols found in whole fruit rendered in a patented double extraction technique.
These important molecules help reduce oxidative stress and inflammation, aid in the disruption and prevention of biofilms and strengthen the bladder wall.
- Complete whole fruit polyphenol profile (flavonols, flavon-3-ols, phenolic acids, anthocyanidins)
The Science of UTI Prevention
Clinically proven ingredients. One daily ritual. Spot treatment before intimacy.
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.
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.
Not all 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.
d-Mannose
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.*
UTI Biome Shield™
Look for formulas with:
- 36mg of soluble PACs
- High bioavailability
- Zero fillers or sugar
The best results come from daily use. Prevention works over time—don’t wait for symptoms to start.
Yes—just space them a few hours apart.
Always consult your doctor.
