In addition to medications like antibiotics, many people use natural remedies for UTI prevention and treatment. Cranberry juice and cranberry juice supplements are perhaps the most popular natural treatments for UTIs.
Cranberries contain compounds such as phenolic acids and flavonoids, which may help treat and prevent UTIs. These compounds may help 2 :. Nevertheless, you may wonder whether cranberry juice is effective at preventing and treating UTIs. Some research suggests that cranberry juice and cranberry supplements may reduce the risk of UTIs in certain populations. Findings from other studies have also suggested that cranberry products, including cranberry juice, may help prevent UTIs from coming back in a few different populations, including 5 , 6 , 7 , 8 , 9 :.
This is because cranberry supplements are a more concentrated source of the active compounds thought to be helpful in UTI treatment. One recent study among healthy women with a history of or recurrent UTIs examined the effects of taking cranberry proanthocyanidins daily.
Those who took the high dosage received Proanthocyanidins are a type of polyphenol compound that is naturally concentrated in cranberries.
However, the study found that taking this high dose did not result in a significant reduction in UTIs for the overall group of adult women who had recurring urinary tract infections.
The effect was only significant among those who had UTIs less often In other words, they may be more effective in some people than others 2. Plus, not all studies have found cranberry treatment helpful for UTI prevention.
Researchers acknowledge that larger, high quality studies are needed to better understand how cranberry products affect urinary tract health. While cranberry products help protect against UTI recurrence in some people, evidence supporting the use of cranberry juice and cranberry juice products for improving symptoms in people who have active UTIs is weak.
Another study that included 46 women found that taking cranberry capsules both alone and when combined with antibiotics may help reduce the need for antibiotic use and improve certain UTI-related symptoms in women with active UTIs Thus, its results may not be as robust as the results of a larger, high quality study.
More high quality research is needed to determine whether cranberry products like cranberry juice and cranberry capsules may help treat active UTIs. Evidence suggests that cranberry products like cranberry juice and cranberry extracts may help prevent UTIs from coming back in some people. A high quality study looked at the effects of taking cranberry juice daily in women with a history of recent UTI.
