Optimized energy for prolonged efforts
The SIS Beta Fuel Dual Source is an energy gel developed to meet the demands of endurance athletes. Its advanced formulation provides a concentrated source of carbohydrates that helps maintain performance during prolonged efforts.
1:0.8 ratio for maximum efficiency
This gel uses a combination of maltodextrin and fructose in a 1:0.8 ratio, designed to improve the body's efficiency in using carbohydrates. This balance increases the oxidation of ingested carbohydrates and optimizes energy supply.
High carbohydrate load per serving
Each gel delivers 40 grams of carbohydrates, making it easier to reach the recommended intake of 80 to 120 grams per hour in endurance sports. This helps sustain performance and delay fatigue.
Lower risk of gastrointestinal discomfort
The formulation has been designed to reduce symptoms such as bloating or stomach upset, allowing more comfortable intake during physical activity.
Practical competition format
The gel is consumed directly from the package, enabling quick and easy intake at any time during exercise. It can be used alone or combined with other products from the Beta Fuel range.
Backed by research and elite use
Developed in collaboration with high-level athletes, this gel is part of a range designed to improve performance through advanced sports nutrition solutions.
