Minutes
First, block the attachment
BioBlocD3® reaches the urine in as little as 30 minutes, targeting Type 1 fimbriae to help keep E. coli from attaching.
HOW IT WORKS
One capsule daily.
Two more before sex.
UTI Biome Shield® is a multi-defense formula designed for recurrent UTI prevention. It targets four places recurrence can take hold: bacterial adhesion, the bladder lining, biofilm, and the microbiome.
Stop a UTI before it starts.
BEYOND ANTI-ADHESION
Transform the root of recurrences
Recurrent UTIs aren't driven by one mechanism, so UTI Biome Shield® works on all of them.
BEYOND ANTI-ADHESION
Block Bacterial Adhesion
Adhesion
Attachment is the first step of every UTI. If bacteria can't hold on, they leave with your urine.
Why attachment matters
E. coli reaching the bladder isn't unusual, it happens routinely. Infection starts when it anchors to the bladder lining instead of being flushed out. It anchors using fimbriae, hair-like structures that lock onto sugar molecules on the surface of urothelial cells.
Blocking both attachment pathways
Type-1 and P-type fimbriae use different adhesion mechanisms, which is why targeting more than one pathway may provide broader anti-adhesion support. D-mannose blocks only one: Type-1, which is part of why trials of D-mannose on its own have been mixed. PACphenol blocks both, and weakens the fimbriae themselves.
BEYOND ANTI-ADHESION
Urothelial Repair
Bladder wall
Your bladder lining is a barrier. Supporting its integrity is an important part of urinary defense.
What the bladder lining (urothelium) does
The bladder lining is sealed by tight junctions between cells and a protective layer above them. When that barrier thins or is damaged, after an infection or after menopause, UTI-causing bacteria have an easier path in.
Rebuilding the barrier
Vitamin D3 supports the proteins that hold those junctions closed and upregulates antimicrobial peptides your body makes itself. Zinc supports the epithelial repair that follows an infection.
BEYOND ANTI-ADHESION
Biofilm Disruption
Biofilm
Biofilm is where bacteria wait between infections.
Why UTIs come back
Bacteria that survive an infection can embed in biofilm, a self-made matrix on the bladder lining and inside urothelial cells. It shields them from your immune system and from antibiotics, which is how a course of treatment can clear symptoms without clearing the reservoir.
Targeting multiple stages
UTI Biome Shield® targets biofilm at several points, from initial formation through to survival.
BEYOND ANTI-ADHESION
Microbiome Balance
Microbiome
Most recurrent UTIs begin in the gut, not the bladder.
The gut reservoir
UTI-causing E. coli lives in the gut between infections, and recurrences are often the same strain returning. The vaginal microbiome matters too, since Lactobacillus keeps pH balanced and crowds out the bacteria that travel.
Feeding the right bacteria
Cranberry polyphenols and D-mannose both have prebiotic activity, supporting beneficial species without added fiber that can cause bloating.
Timing and dosing matter for UTI Prevention
when to take it
Timing and dosing matter
One capsule daily. Two additional capsules before sex. The daily dose builds urinary health protection over weeks and months. The extra dose covers the moment that starts most infections.
Daily — one capsule
Consistency matters more than timing here, because the microbiome, bladder wall, and biofilm work compound over weeks and months rather than hours.
Before sex — two capsules
Take two additional capsules 30 minutes to an hour before sex. BioBlocD3® anti-adhesive support gets flushes the system. If you forget, taking them after is still better than skipping.
Why the extra dose exists
For many women with recurrent UTIs, sex is a major trigger. Friction can move bacteria toward the urethra. The extra dose increases anti-adhesive compounds in the urine during the window when exposure risk is highest.
UTI Biome Shield®
How bacterial anti-adhesion works
An infection starts when E. coli holds on. It attaches using two different arms, so blocking one leaves the other working.

Hours
Then, broaden the defense
PACphenol® targets both Type 1 and P-type adhesion pathways, helping further interfere with E. coli’s ability to hold on.
Flush
No grip. Time to flush.
When bacteria can’t hold on, they are flushed out naturally with urine

UTI Biome Shield® | Transform your urinary health
UTI protection that builds over time
UTI Biome Shield® works on two timelines. Anti-adhesion support starts quickly, helping interfere with bacterial attachment when exposure risk is highest. With consistent daily use, the formula also supports the bladder lining, immune defenses, biofilm response, and a balanced urinary and vaginal microbiome. Different defenses. Working together over time. See Clinical Evidence
-
30 Minutes
Rapid Protection
Take two before sex. BioBlocD3® starts working within 30 minutes, and PACphenol® follows a few hours later. Two complementary anti-adhesion actives block Type-1 and P-type pathways, making it easier for bacteria to be flushed out naturally.
-
Weeks
Strengthen & Defend
Daily vitamin D3, zinc, and polyphenols support the bladder lining and immune defenses, target biofilm where bacteria hide.
-
Months & Beyond
Lasting Balance
Consistent prebiotic and polyphenol support shifts the gut environment away from UTI-causing bacteria, promoting a balanced urogenital microbiome that supports long-term urinary and vaginal health.
