Why doesn Roctane contain the antioxidant vitamins in original GU?
Roctane does not contain the vitamin C or vitamin E that is in GU in order to make room for the additional volume of ingredients in Roctane. Since it is fairly easy to obtain your daily recommended intake of vitamins C and E by ingesting one or more packets of original GU, we removed them in favor of accommodating the added OKG and other increased concentrations of ingredients which are beneficial on those really hard days. If you are concerned about getting enough antioxidants, we suggest including a packet of original GU, in addition to Roctane, as part of of your nutrition program during intense training and racing.
