First Endurance EFS Energy and Hydration Drink Mix

First Endurance EFS Energy and Hydration Drink Mix is made to fuel your toughest rides and races. This drink mix is a scientifically formulated blend of carbs and five essential electrolytes to keep you hydrated and fueled. With sodium, potassium, chloride, calcium and magnesium, EFS drink mix delivers immediate energy and helps prevent cramping and dehydration.

EFS drink mix is also isotonic, which means you can consume it without the need for additional water for digestion. This mix is available in Lemon Lime, Orange and Sour Watermelon flavors. Each of these add taste without being overwhelming. Whether you’re training in the heat, preparing for long endurance rides or racing hard, EFS offers a complete hydration and energy solution you can count on.

Considerations

This product is hydration focused. This means riders with low sodium needs or shorter event durations may prefer a lighter hydration mix. It is also not as high in carbs as other drink mixes, which is crucial for long rides.
