D-Mannose better: The component in cranberry juice that prevents 90% of uti's is d-mannose. Taking d-mannose is a more efficient way to prevent uti's. 1/2 tsp 1-2x/day is usually effective. See http://bit.Ly/1hzudgk for details. Research does show cranberry juice can help prevent recurrent uti's but you would have to drink large amounts to get adequate amounts of d-mannose, in fact we don't know exactly how much.

It Does Prevent: Cranberry juice makes the urine acid which prevents bacteria to grow.Drink a 6 ounce glass twice a day.
