Description

These chews are part of the wider Beta Fuel system and have been expertly developed with elite athletes and sports scientists. The dual-source carbohydrate formula uses a precise 1:0.8 maltodextrin-to-fructose ratio, designed to increase carbohydrate oxidation rates and improve performance output. Unlike traditional 2:1 products, this ratio is proven to enhance how efficiently your body uses ingested fuel while reducing common gastrointestinal issues.

Designed for ease of use on the go, each chew bar can be split into smaller pieces to tailor intake based on your fuelling strategy. Whether you’re running an ultra, riding long climbs, or racing hard, Beta Fuel Energy Chews deliver quick energy without the bulk of traditional bars or the stickiness of gels. They’re light on the stomach, fast to act, and simple to carry.

Ideal for those who want a chewable alternative to drinks or gels, Beta Fuel Energy Chews provide a reliable, performance-enhancing energy source that supports your endurance goals with precision and science-backed efficiency.

How does it work

Beta Fuel Energy Chews utilise a 1:0.8 maltodextrin-to-fructose carbohydrate ratio, which scientific studies have shown to outperform traditional fuelling products. This ratio increases the rate of exogenous carbohydrate oxidation (how well your body uses external carbs) by 17%, which translates to more efficient energy use during prolonged effort. Athletes using this formula also experienced a 3% improvement in power output during sprint efforts and a reduction in GI discomfort such as bloating or nausea, issues often reported with more sugary or imbalanced carb products.

The dual-source carbohydrate system enables your body to absorb and utilise more carbohydrate per hour, pushing oxidation efficiency up from 62% to 74%. This means more of what you consume is actually turned into usable energy, helping delay fatigue and boost overall performance.
