If you are in it for the taste, this isn't it.
I bought the green apple and the taste is not good.  I wish the artificial sweeteners weren't in this but I understand why vs. the calories associated with real sugars.  All of that said, I believe there was an improvement in my energy and focus and I felt as if I went longer before needing any kind of a break. It seems to do what it says it does but the taste is where this needs improvement.
