Description

The optimal carb blend in Beta Fuel Gels allows for more efficient carbohydrate oxidation and energy production, helping athletes sustain prolonged effort without hitting the wall. It’s a key part of the SiS Beta Fuel range, developed in collaboration with elite athletes to meet the latest fuelling science.

The 1:0.8 ratio used in Beta Fuel Gel has been shown to improve exogenous carbohydrate oxidation by 17% compared to more traditional 2:1 formulas. That means your body is able to turn more of what you consume into usable energy, improving performance and delaying fatigue. This formula also supports a 3% increase in mean power output during maximal sprint efforts, making it ideal not just for steady-state endurance but for sessions with bursts of high intensity.

Another major benefit of the Beta Fuel Gel is its role in reducing gastrointestinal discomfort, a common barrier for athletes during long training sessions or races. The optimised carb blend helps minimise stomach fullness and nausea, offering a smoother fuelling experience even during tough efforts. Whether you’re racing or putting in long hours of training, this gel is designed to deliver energy without compromise.

Compact, portable, and easy to consume, the Beta Fuel Gel fits effortlessly into your fuelling plan. Whether used alone or as part of a mixed fuelling strategy with Beta Fuel drinks or chews, it helps athletes hit their target carbohydrate intake of 80–120g per hour with consistency and ease.

How does it work

Beta Fuel Gel is built around a scientifically validated 1:0.8 maltodextrin-to-fructose ratio, which allows the body to absorb and use more carbohydrate per hour than traditional ratios. This increased efficiency results in greater exogenous carbohydrate oxidation, up to 74% of the ingested carbs are used for energy, enhancing both sustained energy and sprint performance.

At the same time, this ratio helps reduce the risk of gastrointestinal issues like bloating and nausea that often come with high carbohydrate intake. By improving both absorption and comfort, Beta Fuel Gel ensures your body gets the energy it needs without digestive distractions, supporting you from start to finish.
