Cranberry Juice Now Unlikely to Prevent Cystitis, University of Stirling Study

Cranberry juice provides no meaningful protection against cystitis, contrary to the belief of large numbers of women, say scientists. A review of findings from 24 studies involving 4,473 participants found no evidence that cranberry juice, or supplements, can be used to prevent bladder and kidney infections. Cystitis is a stinging inflammation of the bladder usually caused by a urinary tract infection (UTI). It can also be triggered by irritation during sexual intercourse, leading to its nickname the “honeymoon disease”.
