First Endurance EFS (Electrolyte Fuel System) is unlike any other endurance drink mix available. EFS combines the latest clinical research and nutritional technology with input from some of the best endurance athletes in the world. The result: a great-tasting energy drink that provides ALL the ingredients you need to maximize endurance during exercise. For example, each serving of EFS provides all five electrolytes (over 1,000mg/serving) in the levels endurance athletes need to stay hydrated, prevent cramping and maximize endurance. With EFS, you don’t need to carry extra electrolyte pills or bother adding anything to your energy drink anymore. Times have changed.

• Provides Complex and Simple Carbohydrates for Superior Energy and Endurance
• Delivers 1000mg Electrolytes Per Serving
• Prevents Cramping and Dehydration
• Provides Free Form Amino Acids to Delay Mental Fatigue

Consuming carbohydrates during prolonged exercise enhances performance by supplying energy for muscles to use when glycogen stores begin to drop. EFS was specifically formulated to deliver the ideal blend of complex carbohydrates, glucose (dextrose) and sucrose for energy. Clinical research shows a combination of carbohydrates is better than a single source for the absorption and utilization of blood glucose. EFS also provides three different high-glycemic sources of carbohydrates for immediate energy and easy digestion during long and intense workouts. The low osmolality of the EFS energy drink and ideal 7% carbohydrate solution provides superior fluid absorption.

• Mix of three carbohydrate sources
• High-Glycemic
• Clinically effective 7% carbohydrate solution

EFS is the first endurance drink to be fortified with clinically effective doses of the amino acids Glutamine, Leucine, Iso-leucine and Valine. These key amino acids have been shown to improve glycogen re-synthesis and delay central (mental) fatigue through their positive influence on the tryptophan/branched chain amino acids. EFS is also fortified with 200% RDA of vitamin C to enhance the body’s immune function, fight free radicals and keep you healthy for future training and racing.

• 2000mg Amino Acids
• Delay Central (mental) fatigue
• Vitamin C for improved immune function and antioxidant protection

Fluid loss plays a major factor in performance. Studies show that when you lose 2-3% of the body’s water through sweat, performance decreases by up to 7%. . This can be the difference between winning and not even finishing. Clinical research shows endurance athletes require much higher levels of electrolytes than most sports drinks provide. EFS deliver all five electrolytes (over 1,000 mg/serving) in the levels endurance athletes need to prevent cramping and dehydration.

• Delivers over 1,000 mg electrolytes per serving
• Helps reduce cramping and dehydration
• Eliminates need to supplement with additional electrolytes
