Cranberry juice is a popular and generally effective treatment for bladder infections. Since it gets filtered through the kidneys first, cranberry juice may help keep kidneys healthy. Bladder and urinary tract infections are unpleasant. Kidney infections that result from bacteria traveling from the urinary tract to the kidneys can be deadly. Cranberry juice can also prevent kidney stones.
Choose cranberry juice, not concentrate or cocktail. Straight cranberry juice can be a bit tart, so dilute with water.
