CRANBERRY EXTRACT
Background and Date of Approval
Cranberry extract is used in dietary supplements to support urinary tract health. It contains antioxidants including vitamin C and proanthocyanidins. Research indicates that cranberry products may reduce the incidence of symptomatic, culture-verified urinary tract infections (UTIs) in specific populations, including women with recurrent UTIs and children without neurogenic bladders. Mild gastrointestinal side effects may occur with cranberry products.

Can cranberry extract cure urinary tract infection?

How does cranberry extract help in urinary tract infections?
Cranberry extract helps prevent urinary tract infections (UTIs) by containing proanthocyanidins, which stop harmful bacteria, like E. coli, from attaching to the walls of the urinary tract. This reduces the risk of infection. However, it does not treat an active UTI and should be used as a preventive measure.
