D-Mannose is natural prebiotic sugar found in fruits such as cranberries and blueberries. Ingested in large enough amounts, it serves to line your urinary tract. It is thought that this prevents e-coli and other pathogens attaching themselves to the walls of your urinary tract as easily, helping to protect from re-occurring infections. Why it's so good D-Mannose is not digested and converted into energy like other sugars such as glucose, fructose and sucrose, making it a diet-friendly solution. It can be found in fruits and vegetables, but only in small quantities.
