Goji Juice at Costco

I noticed that Costco is now selling Himalayan Goji juice. "http://www.costco.com/Browse/Product.aspx?Prodid=11204694";

Costco version
--------------
Reconstituted Juice from Whole Lycium barbarum Fruit, Grape Juice Concentrate, Apple Juice Concentrate and Natural Flavor, Malic Acid, Potassium Sorbate and Sodium Benzoate

$17/30 ounces


MLM version
-----------
Reconstituted Goji Juice from whole Lycium Barbarum fruit, grape juice concentrate, pear juice concentrate, apple juice concentrate, pear puree and natural flavor, with sodium benzoate and potassium sorbate.

Is there any evidence that this stuff does anything at all other than empty your wallet?
