Beta Fuel Powder

What Our Gearhead® Experts Are Saying:

"I started using the Science in Sport Beta Fuel Powder on my longer mountain runs, and it changed how I felt in the back half of efforts that used to fall apart around hour three. The isotonic formula mixes clean with no GI issues, and pairing it with a gel on the hardest hours kept my energy locked in from start to finish."

Long efforts have a way of exposing weak links in your fueling strategy, and the back half of a big day is where underfueling becomes impossible to ignore. The Science in Sport Beta Fuel Powder was developed specifically for those situations, delivering 80 grams of carbohydrate per serving in a formulation designed to maximize how much energy your body can actually absorb and use during extended exercise.

The dual-source approach combines maltodextrin and fructose in an optimized 1:0.8 ratio, a formulation that uses two separate carbohydrate transport pathways to increase total absorption beyond what a single-source drink can deliver. The result is more usable fuel per hour without the gastrointestinal distress that high-carbohydrate loading often brings, thanks to a neutral pH isotonic formula that minimizes gut stress even during high-intensity efforts. Each sachet mixes into 600ml of water in seconds and is designed to be sipped consistently throughout the hour rather than taken all at once. Stack it alongside Beta Fuel Gels or Chew Bars to hit the 80 to 120 gram per hour carbohydrate targets that endurance research now supports for efforts over two hours. Informed Sport certified and developed alongside elite athletes, it is the kind of nutrition product that earns its place in your kit by actually working when you need it most.
