The Science of 4:1

The Science of 4:1

What's the 4:1? It's the unique ratio of 4 parts carbohydrate to 1 part protein in Accelerade, Accel Gel and Endurox R4 that fuels superior endurance, performance, hydration and recovery.

Until the late 1990s, exercise and post-exercise nutrition for athletes was all about carbohydrates. Then a group of leading exercise physiologists came together to formulate the next generation of sports nutrition products based on the very latest science. They discovered that a 4:1 ratio of carbohydrate and protein compared to carbohydrate alone significantly

• Enhanced hydration
• Increased endurance
• Reduced exercise-related muscle damage
• Accelerated post-exercise muscle recovery

Accelerade sports drink, Accel Gel sports energy gel, and Endurox R4 performance recovery drinks are the only drinks on the market containing the patented 4:1 ratio.
