SiS Beta Fuel Boxes

SiS Beta Fuel System: The Pro Cyclists’ Secret Weapon 

Science in Sport didn’t just create another sports drink – they rewrote the playbook on high-carb fueling. Their 1:0.8 maltodextrin-to-fructose ratio became the worst-kept secret in professional cycling, quietly powering wins while the rest of us suffered through sugar crashes and gut bombs.

Now it’s your turn. Buy any two boxes, get one free 🇫🇷 – because breakthrough science shouldn’t be limited to the pros.

The Formula That Changed Everything

The 1:0.8 ratio delivers 74% carbohydrate oxidation efficiency versus 62% with old-school formulas.

Translation: your body actually uses what you feed it, with 30-50% more carbs and significantly less stomach revolt. The pH-neutral solution keeps your gut happy while your legs keep turning.

Three Ways to Fuel, One Perfect System

Beta Fuel Gel (40 g carbs): Concentrated rocket fuel for when you need maximum carbs, minimum volume. Perfect for race finishes and interval sessions.

Beta Fuel Drink Mix (80 g carbs): Your baseline hydration powerhouse in Orange, Strawberry & Lime, and Red Berry. All are naturally flavored because artificial sweeteners have no place in serious fueling.

Beta Fuel Chews (45 g carbs): Two large blocks per pack – no more juggling tiny pieces while hammering. More carbs than any other chew, easier to track, impossible to mess up.

The SiS Beta Fuel System Advantage

Mix, match, and stack without fear. The consistent 1:0.8 ratio across all products means you can layer drink mix, gels, and chews to hit 120 g+ carbs per hour without the digestive chaos.

Start with the drink mix for your foundation, spike with gels during key efforts, and sustain with chews for variety.

This isn't just better sports nutrition – it's the end of choosing between performance and gut health.
