Mezcla de bebida First Endurance EFS de 30 porciones

First Endurance EFS Drink Mix 30-Serving is a purpose-built endurance fuel formulated around a 2:1 glucose-to-fructose carbohydrate ratio, delivering 30 grams of carbohydrates per serving for sustained energy output during long efforts. The isotonic formula is designed to promote rapid absorption while minimizing GI distress — a real consideration when you're deep into a long ride or race.

Each serving supplies a clinically dosed blend of all five essential electrolytes: sodium, potassium, chloride, calcium, and magnesium. Citric and malic acids are included to support ATP production and oxygen uptake. The formulation omits artificial flavors, colors, and additives like vitamin C that can interfere with endurance performance. Available in four flavors — Fruit Punch, Lemon Lime, Orange Splash, and Sour Watermelon.
