Wow, you guys are really uneducated on this stuff. By the way, Acai is one of the lowest of the fruit in terms of ORAC value, Goji is estimated to have an ORAC value around 25,000!
Also, all the drinks have less than 15 grams of suger per ounce, and your to only take 1-2 ounces daily.. Compared to other things, that is VERY low.
Also I remember hearing from doctors that Sugar from fruit has no harm on the body because it's natural and the body utilizes it correctly, unlike artificial suger.
