Urinary tract infections (UTIs) are a common issue, particularly among women. While antibiotics are the go-to treatment, many people look for natural ways to reduce the risk of future infections. One of the most researched options is the use of a cranberry supplement. From its antioxidant properties to its impact on bacterial adhesion, the benefits of the berry go well beyond juice.
Key Takeaways:
- Cranberry supplements may reduce UTI recurrence in women with frequent infections.
- Proanthocyanidins (PACs) in cranberries prevent bacteria from sticking to the urinary tract.
- Effectiveness varies depending on the population and product type.
Do They Really Prevent UTIs?
Cranberries are rich in a group of compounds called proanthocyanidins (PACs). These PACs help prevent E. coli—the main cause of UTIs—from sticking to the lining of the urinary tract. This makes it harder for the infection to take hold. According to a Cochrane review, cranberry products reduced the risk of symptomatic UTIs in women with frequent infections.
What the Research Says
Several clinical studies back the use of cranberry supplements for UTI prevention. A widely cited review published by the American Family Physician showed that cranberry extract significantly lowered the rate of recurring UTIs in women.
The U.S. Food and Drug Administration (FDA) issued a qualified health claim in 2020: consuming 500 mg of cranberry daily may reduce the risk of recurrent UTIs in healthy women. Although the FDA notes the evidence is limited, nsthis recognition points to the powerful berry's potential.
Choosing the Right Supplement
It’s important to distinguish between sugary cranberry juice cocktails and high-quality supplements. Supplements often contain concentrated PACs in standardized doses, making them a more reliable option. For maximum cranberry benefits, choose products with at least 36 mg of PACs per serving—the level used in many clinical trials (NCBI source).
