Cranberry & D-Mannose
A powerful combination to prevent urinary tract infections by targeting bacterial adhesion.
Also known as: UTI Prevention Duo
Overview
Cranberry and D-Mannose are two of the most effective natural supplements for preventing urinary tract infections (UTIs). Cranberry contains Proanthocyanidins (PACs) which prevent E. coli from sticking to the bladder wall. D-Mannose, a simple sugar, works by a similar mechanism, attaching to E. coli bacteria so they can be flushed out of the system during urination. Together, they offer a potent, non-antibiotic approach to maintaining urinary tract health.
Key Benefits
Prevents Bacterial Adhesion
Both ingredients work to stop E. coli, the primary cause of UTIs, from adhering to the urinary tract lining.
Reduces UTI Recurrence
Regular use has been shown to significantly decrease the frequency of recurrent UTIs in women.
Supports a Healthy Urinary Tract
Helps maintain a healthy microbial balance in the urinary system.
Non-Antibiotic Approach
Provides an effective alternative to prophylactic antibiotics, without contributing to antibiotic resistance.
Dosage & How to Take
Look for cranberry extracts standardized for PAC content.
| Purpose | Dose | Notes |
|---|---|---|
| Daily Prevention | 500 mg Cranberry + 1 gram D-Mannose | Take once daily. |
| Acute Support (at first sign of UTI) | 1-2 grams of D-Mannose every 2-3 hours for 24-48 hours | Drink plenty of water. |
Best Time to Take
For prevention, take daily at any time. For acute symptoms, dose frequently throughout the day.

Scientific Research
D-mannose: a promising support for acute cystitis in women. A pilot study.
D-mannose was found to be effective in reducing symptoms and preventing recurrence of acute cystitis, with a better side effect profile than antibiotics.
