Have a bottle of MonaVie Acai Blend juice I just opened it and tastes really sour I don't know if its gone bad or that's how it tastes What could happen if I were to drink it and it was spoiled?

The juice should not taste sour or bad at all. I no longer take it or sell it due the fact that out of 3 cases, one of which I sold to a friend...3 of the bottles were BAD! The one she had was real bad which was confirmed by her, me and the guy above me. 2 of the bottles I had tasted funny but I too wasn't sure if that was ok, until the second bottle when I got real sick. I first noticed foul smelling BM's and a very bad headache (I do not get headaches unless there is a reason) and I was light headed for a weak till I stopped taking it. This was during and after my real bad headache.

I do not recommend this juice to anyone and the price sure isn't worth any benefits (which after 8 bottles I experenced none) it may offer...or you "think" it may offer.
