Juice Plus only offers their unreviewed studies as "proof" that it works. They discourage the people that sell it from reading any contradictory studies. Just because something is bioavailable doesn't mean it is good for you! The stuff in the pills is more processed that what you get in a twinkie. You need the fiber from the real foods more than you need the phytonutrients that are supposedly in the pills. Its 10 times cheaper to buy the same stuff in a different can at Trader Joes.
It is obvious you have not read the published clinical studies on JuicePlus nor lend any credit to the Universities and Medical Centers that have actually done the research. I guess they are all wrong and you are right.
