Hi I have been taking Monavie during my whole treatment but I also take other natural vitamins and supplements so I couldnt tell you if and or how the Monavie is helping me. I think it helps but I know there are other acai berry products out there that arent so expensive. I didnt have to pay for this because my mothers friend sells it and she bought it for me after I researched it. I know it hasnt hurt me and my mother took it also for a while and she said it gave her energy and helped her sleep too. I have a web page of a man who helped me a lot http://www.maximummilkthistle.com/interview.htm This has nothing to do with Acai but is very helpful. Feel free to ask me anything I have run out of more to type more.
