The reformulated Peach-Mango Endurance is a large improvement over the original version. We find the new version to be much cleaner and refreshing, with the fruit flavors providing a sweet splash of flavor to this otherwise light product. The use of ribose ("the primary source of cellular energy") as this product`s key ingredient is a unique twist to the product, but it`s not likely to get extra mainstream attention as the result of this. However, this product still has a lot to offer with the combination of low carbs/calories and great taste -- so we don`t think that will matter all that much.
