Based on the Award Winning complex carbohydrate found in standard EnergySource, 4:1 is easy on the stomach, hypotonic and refreshing.

Performance proven in the toughest races, 4:1 also contains a unique H E A C (high electrolyte anti cramp) formulation. This is designed to maximize fluid absorption in and minimize cramp.

Most endurance athletes should be aware the primary cause of fatigue is the depletion of muscle and liver glycogen (carbohydrate) and that ingesting carbohydrates during exercise will delay the onset of this fatigue. However many athletes remain unaware that EnergySource 4:1 containing 4 parts Carbohydrate and 1 part Protein can extend the time to fatigue up to an incredible 29% when compared to a carbohydrate only drink and 57% when compared with water.
