"My performance has been taken to the next level thanks to First Endurance. Since switching to FE in 2019, I have been able to absorb more carbohydrates and fluids during races and training. It gives me confidence on the start line knowing I have a leg up on the competition with the best sports nutrition products available."

Q: What is EFS?

The EFS formula utilizes the latest clinical research on endurance nutrition and input from some of the best endurance athletes in the world.

A: Clinical research shows that a 6-8% solution delivering between 45-60g carbohydrates, >1000mg Amino Acids, 400-600mg sodium and equivalent balance in all electrolytes should be taken every hour during exercise. EFS is designed to maximize all these levels. Athletes should consume one serving for every 30 minutes of intense exercise. Adjustments should be made based on body weight, training state, 17
heat, individual sweat rates and preference. Use one serving for every 30 minutes as a starting point and adjust as necessary from there.
