ANSWER: D-mannose is commonly used as a dietary supplement to help prevent and treat urinary tract infections (UTIs).
When bacteria attach to the urinary tract and cause an infection, D-mannose can help to flush the bacteria out of the urinary tract and prevent them from attaching to the bladder or urinary tract walls.
This can help to reduce the risk of developing a UTI and can also help to clear an existing UTI. D-mannose is available in capsule or powder form and can be mixed with water or other beverages for easy consumption.
In addition to its use for UTIs, D-mannose may also have potential benefits for other conditions, such as allergies and chronic fatigue syndrome, but more research is needed to fully understand its effects. Consult with your healthcare provider to determine if D-mannose is appropriate for your individual needs and to determine the appropriate dosage.
