Our Members Asked:
Can cranberry juice or cranberry supplements help prevent urinary tract infections or improve overactive bladder?
Answer:Cranberry has been used with some success by women for many decades to prevent urinary tract infections (UTIs). Certain compounds in cranberries limit the ability of E. coli bacteria that cause the infection to attach to the walls of the bladder and urinary tract and gain a foothold. In 2020, the FDA began allowing certain types of cranberry juice and cranberry supplements to claim that they help reduce the risk of recurrent UTIs.
Evidence from one clinical trial also suggests cranberry may reduce symptoms of overactive bladder.
ConsumerLab explains what to look for when choosing a cranberry juice or supplement (including products such as Ellura/Urell) to help prevent UTIs, and how products such as Ellura, AZO Cranberry, TheraCran and Ocean Spray's Cranberry +health chews differ.
