D-Mannose is a type of simple sugar, similar to glucose, but with a different structure. It is found naturally in some fruits, including cranberries. D-Mannose supplements are available in powder or capsule form.
The primary use of D-Mannose is to support urinary tract health. It is believed to prevent certain bacteria, such as E. coli, from adhering to the walls of the urinary tract, helping to flush them out of the body. As a result, D-Mannose is often used as a natural remedy for preventing and managing urinary tract infections (UTIs).
