For urinary tract infection (UTI) support, Maxi Health Research is pleased to introduce Maxi UTI. It contains kosher D-mannose. Maxi UTI also contains Cranmax, a patented cranberry extract. Urinary tract infections are most often caused by E. coli bacteria entering the urinary tract and attaching themselves to the cell walls. The resulting infection can spread further, sometimes even to the kidneys. D-mannose is a simple sugar occurring naturally in many plants. CranMax is more effective than cranberry juice because it gives you the benefit of the entire cranberry including the fruit, seeds, skin, fibers, and juice.
