Overview
Is the SiS Beta Fuel 80 Drink Mix Box of 15 the right buy for regular training?
The SiS Beta Fuel 80 Drink Mix Box of 15 is a full training-block supply of the highest carbohydrate dose in the Beta Fuel range: 80g of dual-source carbohydrates per sachet in the 1:0.8 maltodextrin-to-fructose ratio, ready to mix into a bottle and go. As the liquid foundation of a high-carb fueling strategy, the drink mix is how most serious endurance athletes start each hour of a long effort, supplementing with gels and chews to reach 80 to 120g of carbohydrate per hour. Science in Sport demonstrated in peer-reviewed research that athletes fueling at this rate with the Beta Fuel ratio achieved peak carbohydrate oxidation of 1.58g per minute with zero GI distress, the highest rate ever published.
Available in Lemon and Lime, Orange, and Red Berry. The powder dissolves cleanly, the flavor is light and race-day palatable, and the 15-pack covers you for 15 long rides without restocking. Informed Sport certified, every batch independently tested against the WADA banned substances list. If you train consistently at the level where high-carb fueling matters, this box is the efficient way to stock your nutrition for the block.

Get to know Science in Sport

There's more to Science in Sport than this one product. Our Science in Sport page has the full Science in Sport lineup we carry and more about the brand.
Visit the Science in Sport page →How do I use the Beta Fuel 80 Drink Mix?
Mix one sachet into approximately 500ml of water. Use one bottle per hour as your carbohydrate base during sustained efforts, supplementing with gels and chews to reach your individual 80-120g per hour target.
How much carbohydrate is in each sachet?
Each sachet delivers 80g of carbohydrates in a 1:0.8 maltodextrin-to-fructose ratio. A box of 15 gives you 15 sessions of base carbohydrate fueling.
Does the Beta Fuel 80 Drink Mix replace electrolytes?
No. The Beta Fuel range is intentionally low in electrolytes. Add HYDRO Tablets or a dedicated electrolyte product to your second bottle, particularly in hot conditions or on high-sweat days.
How does the Beta Fuel 80 Drink Mix fit into a full fueling strategy?
Use the drink mix as your liquid carbohydrate base (80g per hour), then supplement with 1-2 Beta Fuel Gels per hour to reach the 80-120g target. Use Beta Fuel Chews for format variety on long efforts.
