"I'm training for Ironman Florida and during the summer months here in Florida, long bike rides take me into some really hot and humid weather. I've been struggling for 6 weeks with cramping every time my ride hit 60-65 miles in length. I read about e-Fuel and after two rides of 80+ miles with no cramping, I'm a believer!" (read more)

e-Fuel Endurance Blend
vs.
GU Hydration Mix
(formerly GU Brew)

GU Hydration Mix (formerly known as GU Brew) and e-Fuel are drastically different products.

GU Hydration Mix is 50% simple sugar and provides very little substance for endurance athletes with only 27 calories and 95 mg of sodium. If your goal is to just remain hydrated this may be fine, but if you are doing any form of endurance activity you will quickly be running on empty.

With 70% complex carbohydrates and very little sugar, e-Fuel provides three times the energy, double the electrolytes, critical antioxidants and e-Fuel is all natural with NO artificial colors, flavors or sweeteners.

Carbohydrates
Maltodextrin is the preferred carbohydrate source for endurance athletes and as such it is the primary ingredient in e-Fuel ... and it has 4 times as much compared to GU Hydration Mix.
  
Electrolytes
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. GU Hydration Mix has half the electrolytes of e-Fuel.
  
Citrates
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.
  
Antioxidants
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. 
  
Protein
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:

Protein-added Sports Drinks Don't Boost Performance
