Hi - I don't know if it works but I do know that I called for the "free 30 day supply" - and had to pay 4.50 shipping (via my checking account number). When I received the 30 day supply - the info that came with it said it takes 3-4 months for it to work. And, the company has debited by checking account for $35.00 for another months supply - without my knowledge or permission. I would be very careful about this.
