Does cranberry juice really help cure UTIs?
Cranberry juice may help prevent recurrent UTIs for some women, but it does not cure an active infection. Clinical studies show mixed results and it should not replace antibiotics when treatment is required.
Detailed Medical Explanation
Cranberry juice contains proanthocyanidins, which may reduce E. coli bacteria sticking to the urinary tract wall. Evidence is mixed: some studies find a slight reduction in recurrent UTIs, while others show no benefit. Cranberry juice does not treat established infections and is not a substitute for antibiotics. NHS: Cranberry and UTI.
Clinical Context
Clinics may recommend cranberry as part of a prevention strategy, but always advise antibiotics for an active infection.
Evidence-Based Approaches
NICE and NHS note that while cranberry may help some women, it should not be relied upon for acute treatment. Consult a clinician for persistent symptoms.
