Product Description
The Carb-Dense Game Changer
Finally, a sports chew that doesn’t mess around. The SiS Beta Fuel packs 45 g of carbohydrates into just two bars – that’s 30-50% more than any other chew on the market. No more fumbling with handfuls of tiny pieces mid-workout.
The Science That Actually Works
The magic is in the 1:0.8 maltodextrin-to-fructose ratio. This isn’t marketing fluff – it’s a complete rethink of how your body processes fuel. By using different absorption pathways, your muscles get fed without your gut getting wrecked.
The numbers speak for themselves: 74% carbohydrate oxidation efficiency (up from 62% with the old 2:1 ratio) and significantly less stomach fullness.
Translation: more energy, less bloating, better performance.
Dead Simple Fueling
Pop one chew every 30-45 minutes during anything over 90 minutes. Whether you're grinding through a century ride, logging trail miles, or pushing through overtime, these bars deliver consistent energy without the guesswork.
Two bars. 45 g carbs. Zero excuses.

SiS Beta Fuel Energy Chews FAQ's
Everything you need to know about SiS Beta Fuel Energy Chews.



Take one chew every 30 to 45 minutes during any effort lasting longer than 90 minutes, like a century ride, long trail run, or a long race. Two chews deliver 45g of carbohydrate, so you can hit a meaningful chunk of your hourly carb target without stopping to fumble with multiple pieces.
The chews use a 1:0.8 maltodextrin-to-fructose ratio, which taps two separate carb absorption pathways at once. SiS reports this raises carbohydrate oxidation efficiency to 74%, up from 62% with an older 2:1 ratio, so more of what you eat becomes usable energy and less sits in your gut causing fullness.
They're formulated specifically to reduce that risk. The dual-pathway ratio is designed to cut the stomach fullness that high-carb fueling can cause, so you can take in more carbohydrate on long efforts with less GI discomfort than a single-source carb chew.
Both use the same Beta Fuel carbohydrate science, so it comes down to format preference. Chews suit athletes who want something to bite and chew rather than a gel texture, which can help break up the monotony of gels on very long efforts. You can rotate between formats across a race to manage palate fatigue.
They're a core carb source, but most endurance athletes need 80 to 120g of carbohydrate per hour on efforts over two hours. Two chews give you 45g, so on long or high-intensity days you'll likely combine them with gels or a carb drink to reach your full hourly target.
