Strong for recurrent UTI prevention health 5 linked sources Content audit 2026-05-16

Headline Finding

2023 Cochrane update: cranberry products reduced symptomatic, culture-verified UTIs overall and in women with recurrent UTIs.

Dose Context

Trials vary by juice, capsules, extract, and proanthocyanidin content; match use to a studied cranberry product rather than generic fruit powder claims.

Important Caveat

This is prevention evidence, not treatment. Evidence is weaker for elderly institutionalized adults, pregnant adults, and bladder-emptying problems.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
