It is proven to be a medical grade supplement that prevents UTI if taken everyday or two after intercourse if that's what causes your UTI , which that is the main cause of mine... I ordered some but I'm still waiting on it to get here. A lot of women say it works and I will do anything to prevent as many UTI as I can. So if any of you have experience with that or maybe something else that works better at prevention and/ or treatment at the first sign of UTI please let me know :)
