HOT ! SiS Beta Fuel - Strawberry and Lime - Box of 15

SiS Beta Fuel Drink Mix: The Standard-Bearer

Science in Sport didn’t just improve their game-changing drink mix – they perfected it. The Beta Fuel represents the gold standard in high-carb fueling, delivering 80 g of carbohydrates through a proven 1:0.8 glucose-to-fructose ratio that actually works.

The Dual-Pathway Advantage

This isn’t another sugar bomb masquerading as sports nutrition.

The 1:0.8 ratio feeds your system through two separate absorption pathways – maltodextrin and fructose, taking different routes to fuel your muscles without overwhelming your gut. High absorption, high utilization, zero digestive revolt.

Pro-Level Performance, Natural Flavor

Available in Orange, Strawberry & Lime, and Red Berry – all naturally flavored without artificial sweeteners because your taste buds deserve better than laboratory chemicals.

Choose your favorite or rotate through all three; each delivers the same science-backed performance.

Trust the Track Record

Team Ineos-Grenadiers and elite athletes have relied on Beta Fuel since 2017. When your livelihood depends on peak performance, you don’t gamble with unproven formulas.

This is what works when failure isn’t an option.

Clean Label, Maximum Performance

Vegan, celiac-safe, lactose-free, gluten-free, wheat-free, and nut-free. Plus, Informed Sport Certified for those who undergo testing. No compromises, no excuses, just pure fuel.

How to Use It

Mix one serving (82g) with 600ml of water. Get the ratio right – this isn’t a casual sports drink, it\'s precision fueling for when you need maximum carbohydrate delivery. Deploy when your training or racing demands serious energy.
