The otc pill cleartract, does it work as stated?

Nobody knows: This is d-mannose, which binds to the hairs on bacteria that are meant to bind them to the bladder wall. Cranberry juice, a similar inhibitor, is scientifically established in prevention / treatment of bladder infections. There is some preliminary suggestive evidence that d-mannose can do the same -- we await some controlled studies.

Unsure: Agree with Dr. Friedlander. It has shown promising results in rat studies (http://www.discovernutrition.com/research.htm).
