I tired that stuff. It sucks and is a rip off.
There is something I bought at the healthy food store that is very good called "Green Vibrance"

Unlike the mentioned product you'll feel results soon.
I have a vita-mix and love it but it still requires you to buy food and stick it in the thing. If you don't want to do that buy Green Vibrance, organic fruit & super veggie juice at the health food store. Drink a cup of eat a day. DONE. Switch fruit juices but always add apple.
