Cranberry juice may help prevent urinary tract infections by inhibiting bacteria from adhering to the urinary tract walls, promoting urinary health.
Cranberry juice has long been touted as a natural remedy for urinary tract infections (UTIs). But does science back this popular belief? This in-depth guide explores cranberry juice’s effects on urinary health, separating facts from myths.
How Cranberry Juice Affects Urinary Health
Cranberries contain unique compounds that may benefit urinary health:
- Proanthocyanidins (PACs): These plant compounds prevent bacteria from sticking to bladder walls
- Organic acids: Including quinic, malic, and citric acids that may acidify urine
- Antioxidants: Help reduce inflammation in the urinary tract
The Science Behind Cranberries and UTIs
Research suggests cranberry products may help prevent UTIs by:
- Creating a slippery bladder lining that bacteria can’t adhere to
- Making urine more acidic, creating an unfavorable environment for bacteria
- Containing anti-inflammatory compounds that support urinary tract health
A Cochrane review found cranberry products reduced UTI risk by about 26% in certain groups.
Best Ways to Use Cranberry for Urinary Health
Choosing the Right Cranberry Product

|---|---|---|
| 100% pure cranberry juice | High | Most natural form, but very tart |
| Cranberry supplements | High | Standardized PAC content is key |
| Cranberry juice cocktail | Low | Often high in sugar, low in active compounds |
Optimal Dosage
For prevention, research suggests:
- 8-16 oz of pure cranberry juice daily
