Herbal Life??

I have several people talk to me about their experience with Herbal Life products. Today I went to a demo of some sort at my grandmothers house. As I was listening to the presentation I was thinking in my head about all the "real" food that could do the same things. I honestly thing it's a waste of money. Buying fruit and vegetables from the farmer's market is cheaper.

Has anyone else found Herbal Life to work for them? What I want to know is what doctors think about this and how many doctors go out and recommend or use it themselves. To me it seems just like a diet fad.
