Cranberry extract provides urinary tract support without the unwanted sugar found in cranberry juice or juice cocktails, which can encourage the growth of unfriendly bacteria. It enhances the acidity of urine and maintains a healthy urinary tract ecology. One study suggested the potential for cranberry juice to interact with lectin receptors and maintain a healthy bladder wall. At Brigham and Womens 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. d-Mannose, a simple sugar found in cranberries and other fruit, is included in this formula to provide concentrated support. One study examining the effect of d-mannose on epithelial cells suggested that it may play a role in supporting healthy genitourinary function by maintaining a healthy mucosal surface.
