Ideal for cyclists, runners and triathletes who need a portable, adjustable carbohydrate source for endurance sessions longer than two hours.
SIS Beta Fuel Energy Chew is a dual-source, high-carbohydrate energy chew made for endurance exercise lasting more than two hours. Each 60 g orange bar provides 46 g of carbohydrate and 190 kcal, helping you build a consistent fuelling plan for long rides, races and training sessions.
The maltodextrin-and-fructose formula uses a 1:0.8 carbohydrate ratio, while the soft chew format gives you a useful alternative to gels and drinks. Tear it open and eat the bar whole, or break it into individual blocks of approximately 7 g of carbohydrate so you can take smaller amounts at a time. The orange flavour is sweet and easy to consume at pace.
Use 1–3 chew bars per hour during exertion, depending on your event and overall nutrition plan, with SIS recommending a total carbohydrate intake of 80–120 g per hour. You can use the chew on its own or combine it with other BETA Fuel products. It is also Informed Sport certified, with certified products batch-tested for substances prohibited under the World Anti-Doping Agency list.
