DISCUSSION: D-Mannose is a simple carbohydrate similar in structure to glucose. Some unfriendly bacteria have lectins (adhesion molecules), which bind to residues of mannose in the epithelium of the urinary tract. Some clinical experience suggests that supplemental D-Mannose acts as a molecular "chaff" to which bacteria bind, preventing them from binding to urinary tract cells. 100% Vegetarian SUPPLEMENT FACTS: Serving Size: 1 Tablet %DRI D-Mannose ~1g * Non-medicinal ingredients: magnesium stearate.
