First Endurance EFS Drink Mix Single-Serving Info
First Endurance EFS Drink Mix Single-Serving is a purpose-built endurance fuel that covers hydration, energy, and electrolyte replacement in a single scoop. Each serving delivers 30g of carbohydrates via a 2:1 glucose-to-fructose ratio — a combination designed to maximize carbohydrate absorption and reduce GI distress during long efforts. The isotonic formula supplies all five essential electrolytes: sodium, potassium, chloride, calcium, and magnesium, at doses intended to address cramping and fluid loss rather than simply check a label box.
Citric and malic acids are included to support oxygen uptake and ATP production. The formulation skips artificial flavors, colors, and vitamin C — an additive First Endurance omits specifically because high-dose antioxidants have been shown to interfere with endurance adaptation. Available in Fruit Punch, Lemon Lime, and Orange Splash.
