Cranberry pills for UTIs

HERO INGREDIENT

D-mannose that works where UTIs start

A pharmaceutical-grade simple sugar your body doesn't metabolize. It travels to the urinary tract unchanged and acts as a decoy, binding to E. coli before they can stick to your bladder wall.

500mg
Pharmaceutical-grade d-mannose per dose
30 min
Rapid absorption and excretion into the bladder
Type 1 fimbriae
Targets Type 1 E. coli adhesion
90%
Excreted unchanged into urine, where it blocks bacterial attachment

THE SCIENCE

a sugar E.coli can't resist

D-mannose is a naturally occurring monosaccharide. Unlike glucose, your body doesn't metabolize it. It passes through the bloodstream and is excreted in urine largely unchanged, where it becomes available exactly where UTIs start. / E. coli bacteria have tiny hair-like projections called Type 1 fimbriae that latch onto the urothelial wall.

D-mannose binds to those fimbriae with far greater affinity than the bladder lining — so the bacteria grab the sugar instead, and get flushed out with urination.

D-mannose doesn't kill bacteria. It changes the target.

THE MECHANISM

How d-mannose clears E. coli from your bladder

A fast-acting decoy molecule is the first phase anti-adhesion in the bladder in UTI Biome Shield®.

01

Fast Acting

Rapidly absorbed and excreted unaltered into the bladder in as little as 30 minutes without affecting blood sugar. Predictable onset of action allows for dosing before intimacy.

02

Decoy

In the bladder Type 1 fimbriae of E. coli bind to d-mannose with high affinity — far more readily than to the bladder wall itself.

03

Flush

Bacteria coated in d-mannose molecules rather than your urothelium are flushed out with urination. No attachment means no infection.

How cranberry PACs work in the urinary tract

Based on randomized controlled trials of d-mannose in UTI prevention and treatment.

THE RESEARCH

Right dose. Right form. Great for protection before sex.

Clinically proven to reduce UTIs

60%UTI reduction

Clinical studies show d-mannose reduces recurrent UTI incidence vs placebo.

300+participants

Validated in randomized controlled trial against standard prophylactic care.

Dose determines effectiveness

500mgEach Capsule

Supports effective bacterial binding.

30 mintime to action

Fastest-acting UTI prevention ingredient in the formula.

Not all d-mannose is the same

GMPpharmaceutical-grade

Most supplements use food-grade d-mannose with inconsistent purity.

No fillerspure d-mannose

Some products cut d-mannose with glucose. Ours doesn't.

UTI Biome Shield® is antibiotic-free so it doesn't kill the good bacteria in your microbiome.
