Research Summary
Evidence for cranberry extract in UTI prevention is mixed. Several randomised controlled trials show modest benefit for recurrent UTI in women, whilst others demonstrate minimal effect. Meta-analyses suggest potential efficacy primarily in women with recurrent infections, though study quality and PAC standardisation vary considerably. More high-quality research is needed to establish optimal dosing and patient populations.
