Because insubstantial amounts of D-Mannose are used by the body, it does not interfere with blood sugar regulation.* Mannose: A Spoonful of Sugar   Product FAQ's   Online Seminar - Women's Health Issues: Listen to a seminar on women's health issues and the supplements that address some of the most common concerns for women today.  Presented by Dr. Hyla Cass.
