Great Tasting Energizing Sports Drink With 1040mg Electrolytes!
Formerly E3
EFS is an energy drink at the forefront of endurance nutrition that combines the latest clinical research with input from elite endurance athletes. Containing an ideal blend of simple and complex carbohydrates, amino acids, antioxidants and electrolytes, EFS provides endurance athletes the nutrients they need to fuel working muscles and increase endurance during exercise.
Energy: 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 (26, 27, 28, 30). 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. Clinical research shows that energy drinks mixed between 6-8% offer the optimal absorption of both carbohydrates and fluid for endurance racing and training (31,32).
- Mix of three carbohydrate sources
- Clinically effective 7% carbohydrate solution
- High-Glycemic
Endurance: 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 acid ratio (2,3,4,5, 6, 10). Researchers theorize that it is these amino acids, not complete proteins, which provide added performance gains to ingesting carbohydrates alone. Because EFS is fortified with free-form amino acids (not complete proteins) it's a light, easy to digest, great-tasting solution to heavier protein drinks. 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 improve immune function and antioxidant protection
Electrolytes: Fluid loss plays a major factor in performance. Studies show that when you lose 2-3% of the body's fluid through sweat, performance decreases by up to 7% (1,7,8, 9,34 ). This can be the difference between winning and not even finishing. Electrolytes promote the absorption of water during exercise. When you sweat, you lose essential electrolytes, which can result in cramping and dehydration (1,7,9,34). The transfer of nutrients and water in and out of the cell known as cellular respiration requires all five electrolytes in a precise balance for maximum cellular efficiency (1,7,9,34). Dedicated endurance athletes require much higher levels of electrolytes than can be found in most drinks (7,9,34). EFS Fdelivers all five electrolytes in higher amounts than any other product on the market while still remaining isotonic.
- All 5 Electrolytes in levels endurance athletes require
- Helps reduce cramping and dehydration
- Promotes water absorption
