Function Alternative Energy Acai Grape

I didn't expect this to be so fruity. I drank an acai drink earlier today, and this didn't really taste like acai, but it was still tasty. It kind of tasted like if some really good fruit punch was mixed with Vitamin Water. There is a weird mixture of ingredients in this. Purple Sweet Potato Extract? Strange. It is an all-natural energy drink, so that's nice. I always appreciate energy drinks that aren't "toxic tasting" and full of weird man made chemicals.
