The Science Behind Beta Fuel

The new 1:0.8 carbohydrate ratio replaces the traditional 2:1 maltodextrin-to-fructose ratio.

Research into the 1:0.8 ratio has shown an increase in the percentage of ingested carbohydrate that can be oxidised, from 62% to 74%, compared with a 2:1 ratio. It has also been associated with reduced self-reported feelings of stomach fullness.

For endurance athletes consuming large amounts of carbohydrate during exercise, this makes Beta Fuel a practical option for building a high-carbohydrate fuelling strategy while helping to minimise gastrointestinal discomfort.

Built for Endurance

Beta Fuel Energy Drink is particularly suited to athletes competing or training for events lasting 2 hours or more, where maintaining carbohydrate availability becomes increasingly important.

Use it as part of a complete fuelling strategy alongside Beta Fuel Energy Gels, energy chews and other carbohydrate sources.

Perfect for: Marathons, ultra marathons, trail running, cycling, triathlon and long endurance training sessions.
