e-Fuel Endurance Blend
GU Roctane

Ultra Endurance Energy Drink Mix

GU Roctane Ultra Endurance Energy Drink Mix is an outstanding product. In fact, e-Fuel and GU Roctane are very similar products ... with a couple differences you'll like.

Both are low in sugar, high in complex carbohydrates and contain the same ratio of maltodextrin and fructose. e-Fuel does have an edge on electrolytes with about 50% more sodium and 4 times the potassium, and e-Fuel contains critical antioxdants not found in Roctane.

e-Fuel is less expensive to save you a little money, and e-Fuel is all natural with NO artificial colors, flavors or sweeteners.

Ingredient Information and Explanation

Maltodextrin is the preferred carbohydrate source for endurance athletes and as such it is the primary ingredient in both e-Fuel and Roctane.
e-Fuel is designed to provide complete and balanced electrolyte replacement that is critical for proper hydration and to avoid muscle cramping. The sodium and potassium levels in e-Fuel are designed to meet the American College of Sports Medicine's recommendation for electrolyte replacement during intense athletic activity. e-Fuel has about 50% more electrolytes than Roctane.
The Citrates in e-Fuel assist in the carbohydrate to energy conversion process as well as reduce and slow the build-up of lactic acid in your muscles.
e-Fuel is one of the few sports drinks on the market that contains antioxidant vitamins C and E to help protect against tissue damage, reduce soreness and aid in the recovery process.
Neither of these products contain protein but many athletes ask if protein should be in their drink. Protein has to go through a digestive process which draws blood away from working muscles to the stomach and intestines. When you are competing in an aerobic activity you want as much blood as possible supplied to your muscles carrying fresh oxygen for the energy conversion process. Consequently, independent studies have found no benefit of protein in a sports drink. See the following article from the American College of Sports Medicine for a more complete discussion:
