D-Mannose is one of the simple sugars naturally found in cranberries and pineapples known for its ability to assure and nourish the urinary tract. The body metabolises small amounts of D-mannose, but upon excretion much of it passes through the kidney and bladder. In the urinary tract, D-mannose adheres to microorganisms to prevent them from sticking to the bladder walls. visit us: http://www.tasmanhealth.co.nz/now-foods-d-mannose/ for more details!!
