Cranberries are rich in antioxidants, which help protect cells from damage.While not directly related to bladder function, overall cellular health is beneficial for the body's systems.

While cranberry is not a treatment for an existing UTI, cranberries do contain acidic compounds and can slightly increase the acidity (lower the pH) of urine. Historically, it was thought that this acidification killed bacteria, but current understanding suggests this effect isn't significant enough to kill bacteria or treat an active infection.

While less direct, some sources suggest that the general health benefits of cranberries, including their acidity and potential antimicrobial properties, might indirectly contribute to a healthy vaginal environment, which relies on a balanced PH.
