First Endurance New & Improved EFS
EFS drinks provide everything you need to maximize endurance and performance during exercise. You'll notice the difference right away too. With the latest amino acid technology, superior mineral bioavailability and the addition of Malic Acid, EFS drinks refuel working muscles faster than ever before. Plus they taste great, not chalky or overpoweringly sweet. And with the highest electrolyte content available (1160mg of all 5 electrolytes/serving), there's no need to carry those extra electrolyte pills or add anything else. You can train and race with confidence knowing you don't have to worry about cramping or dehydration. Times have changed.
