Description
SIS Beta Fuel Energy Chew: Unlock Your Body’s True Potential.
For years, endurance nutrition was limited. You either had to choke down dry energy bars or consume endless gels. Science in Sport has rewritten the rulebook with the Beta Fuel Energy Chew.
Designed for the elite cyclist, runner, and triathlete, this chew provides a super-efficient way to hit high carbohydrate targets (80-120g per hour) necessary for events lasting over 2.5 hours.
The Magic Ratio (1:0.8) Traditional sports nutrition uses a 2:1 ratio (Glucose:Fructose), which limits how much carbohydrate your body can absorb per hour (usually around 60g). The Beta Fuel 1:0.8 ratio changes the game. By balancing Maltodextrin and Fructose effectively, this chew allows your body to oxidise 17% more carbohydrate and increases your carbohydrate oxidation efficiency to 74%.
What does this mean for you? You get more fuel to your muscles, faster, with significantly less feeling of “fullness” or stomach bloat that plagues endurance athletes in the final hours of a race.
Texture & Taste Unlike oat-based bars that require heavy chewing (and water to wash them down), the Beta Fuel Chew has a firm, jelly-like texture—similar to a high-quality confectionary block. It breaks down easily in the mouth, making it safe and simple to consume even when your heart rate is in Zone 4.

Wetsuit Sizing
What is the texture like?
It is not a baked oat bar or a sticky gel. It has a texture similar to a firm fruit jelly or Turkish delight. It is solid enough to hold its shape in your pocket but soft enough to chew and swallow easily while breathing hard.
Why is the 1:0.8 ratio better than 2:1?
The 1:0.8 ratio allows your gut to absorb carbohydrates through two different transporters (SGLT1 for glucose and GLUT5 for fructose) simultaneously. This prevents the “bottleneck” of traditional nutrition, allowing you to absorb more fuel per hour with less stomach bloating.
Can I use this for short workouts?
You can, but it might be overkill. With 46g of carbs, this is high-octane fuel designed for long, depletion-style efforts (2.5+ hours). For shorter rides (under an hour), a standard GO Gel or lower carb electrolyte drink is usually sufficient.
Is it vegan?
Yes, the SIS Beta Fuel Chews are suitable for vegans and vegetarians.
Will this melt in my jersey pocket?
No. Unlike chocolate-coated bars, these are designed to withstand the heat of the body and warm weather conditions without turning into a mess.

These taste great and open easy with a squeeze or a little bar pop. Easy on the stomach used on 100 mile rides etc
