The SIS Beta Fuel Chew Bar is a new energy bar in the SIS sports nutrition range. Thanks to the soft texture, the Chew Bars are very easy to eat before and during exercise. Per bar of 60 grams, you get no less than 46 grams of carbohydrates to improve your performance. Especially for long duration efforts, this bar is very suitable. The Beta Fuel Bar consists of 6 soft Energy Chews and is easily digestible. The Beta Fuel Chew Bar is available in the flavors Orange and Lemon.

As an endurance athlete exercising for more than two hours, you need to get between 80 and 120 grams of carbohydrates per hour. Our Science in Sport Beta Fuel Dual Source Energy Gel Chews deliver 46g of fast carbohydrates in a convenient and tasty chewable tablet, optimized with a new ratio that increases power output and makes carbohydrate utilization more efficient without gastrointestinal discomfort.


The bar features a 1:0.8 ratio of maltodextrin to fructose. This new ratio of maltodextrin to fructose increases the percentage of ingested carbohydrates that are oxidized from 62% to 74%, compared to the original ratio of 2:1. This formula has been extensively tested and in the process also reduces nausea and stomach stuffiness.
