Beta Fuel Powder

What Our Gearhead® Experts Are Saying:

"I built the Science in Sport Beta Fuel Powder into my fueling plan for a long gran fondo training block, and the difference in how I felt at hour four was significant compared to what I had been using before. The 1:0.8 maltodextrin to fructose ratio is dialed in for maximum gut absorption, and pairing one sachet per hour with a Beta Fuel Gel on the hardest climbs kept my power numbers consistent late into rides where I used to fade badly."

High-carbohydrate fueling during prolonged cycling efforts is no longer a fringe strategy. The research is clear that athletes capable of absorbing more carbohydrate per hour sustain higher power outputs for longer, and the limiting factor is usually gut tolerance rather than willingness to fuel. The Science in Sport Beta Fuel Powder was formulated to address exactly that constraint, delivering 80 grams of carbohydrate per serving in a dual-source ratio that pushes absorption efficiency beyond what single-source drinks can achieve.

The 1:0.8 maltodextrin to fructose ratio uses two distinct intestinal transport pathways simultaneously, meaning the gut is processing both carbohydrate types in parallel rather than queuing them through a single channel. This translates directly to higher total carbohydrate delivery per hour without the bloating and distress that typically accompanies aggressive fueling strategies. The isotonic, neutral pH formula further reduces GI stress by matching the osmolality of the drink to that of the body's fluids, making it suitable for use even at threshold and above, where gut motility slows and sensitivity increases.

Each 82-gram sachet mixes into 600ml of water and is designed for steady sipping across the full hour rather than bolus consumption. Used at one sachet per hour as a standalone, or combined with Beta Fuel Gels or Chew Bars to reach the 80 to 120 gram hourly target that current endurance nutrition guidance supports, it builds a flexible and scalable fueling system that works across everything from four-hour gran fondos to multi-day stage efforts. Informed Sport certified with full batch testing documentation, it meets the compliance standards required for competitive athletes at every level.
