CranRich capsules provide a superior source of cranberry's unique health promoting compounds. Cranberry juice (Vaccinium macrocarpon) helps to support a healthy urinary tract. Research has demonstrated that substances in cranberry prevent bacteria from sticking to the lining of the urinary tract and bladder, where they multiply. CranRich is made by Natural Factors using a proprietary process that captures all of cranberry's unique health promoting compounds. The capsules are a potent source of cranberry powder containing a very high 36:1 ratio of concentration. (This means that 36 grams of cranberries equals 1 gram of concentrate.) The capsules are also more convenient to take than cranberry juice, without the added sugar.
