Does Cranberry Juice Actually Help with Utis?
Medically reviewed by Andre Stone | MD, University of Pittsburgh School of Medicine on August 25th, 2026.
Cranberry juice may provide modest protection against recurrent UTIs in some women, but the evidence is mixed. Some studies suggest that cranberry products may modestly reduce recurrent UTIs in some women, but results vary among products and studies. The compounds prevent E. coli bacteria from adhering to urinary tract walls. However, commercial cranberry juices vary in their PAC and sugar content, and it is unclear which formulations or amounts are most effective. Some cranberry extracts and supplements have been studied, but evidence has not established a reliably effective PAC dose or shown that supplements consistently work better than juice. Cranberry products do not treat an active UTI and should not delay medical care. Anyone with possible UTI symptoms—especially fever, back or side pain, vomiting, pregnancy, or worsening symptoms—should contact a healthcare professional. Cranberry products may help prevent some recurrent UTIs, but they are not a substitute for recommended care.
