Cranberry NS nutritionally supports urinary tract health without unwanted sugar which can encourage the growth of unfriendly bacteria. Cranberries have been used for hundreds of years as nutritional support for the urinary tract. Cranberry extract provides support without the unwanted sugar found in cranberry juice varieties, which can encourage the growth of unfriendly bacteria. The role of cranberry extract includes enhancing the acidity of urine and maintaining a healthy urinary tract ecology. Constituents of cranberry extract associated with its benefits include proanthocyanidins as well as d-mannose. In one study, healthy urinary function was observed in subjects shortly after drinking cranberry juice cocktail. Another study suggested the potential for cranberry juice to interact with lectin receptors and maintain a healthy bladder wall. At Brigham and Women's Hospital in Boston, MA, a randomized double blind, placebo-controlled trial involving over 150 female volunteers reported positive support for a healthy urinary tract after administration of a cranberry beverage.
