Molecular formula




Molar weight

180.156 g/mol-1








Significant quantities of D-Mannose can be found in many fruits and vegetables, including peaches, apples, blueberries, green beans, cabbage, and tomatoes. D-Mannose plays an important role in human physiology and can prevent bacteria from sticking to the walls of the urinary tract and causing infection. It can be used for the treatment of urinary tract infections (UTI’s).

D-Mannose is not well metabolized in the human body. Therefore, it does not significantly enter the carbohydrate metabolism when taken orally. 90% of D-Mannose ingested is excreted unconverted into the urine within 30 - 60 minutes, with 99% of the remainder being excreted within the following 8 hours. There is no significant increase in blood-glucose levels during this time. So D-Mannose will not interfere with normal blood sugar regulation. Our product is converted from Glucose, it can also be used in foods, medicine, health products, and cosmetics.

Storage and Stability

The product would be stable for 2 years from the date of manufacture in the sealed original container.

It should be protected from light, heat and moisture, keep the container tightly closed. Reseal immediately after use.



Safety Concerns

D-Mannose appears to be safe when used orally and appropriately. As a sugar widely present in foods, D-Mannose is assumed to be safe. However, the maximum safe dosage has not been established in healthy adults, nor in pregnant and nursing women or young children. Very weak evidence from test tube studies hints that consumption of larger amounts of D-Mannose by pregnant women could conceivably increase risk of birth defects in their children
