D-()-Mannose is commonly used in biochemical and pharmaceutical research cell culture studies and as a carbohydrate reagent in glycosylation and other chemical synthesis applications.

Its primary purpose is to support urinary tract health by helping prevent certain bacteria particularly Escherichia coli (E. coli) from adhering to the walls of the urinary tract allowing them to be flushed out through urine.

D-()-Mannose is a naturally occurring simple sugar (monosaccharide) closely related to glucose. It is found in fruits such as cranberries apples and peaches and is commonly used as a dietary supplement.
