The Core Carbohydrate Mix
SiS Beta Fuel products feature a dual-source carbohydrate blend with a 1:0.8 ratio of maltodextrin to fructose. This ratio is an improvement on the previous 2:1 formula and is designed to enhance the body's ability to absorb and utilize fuel during prolonged exercise, such as events over two hours. This dual-source approach uses two different intestinal transport systems for carbohydrate absorption, allowing athletes to consume and use more energy per hour.
The Role of Maltodextrin and Fructose
Maltodextrin, derived from maize, provides a quick release of glucose for immediate energy, while fructose is processed by the liver for a slower, sustained fuel release. The 1:0.8 ratio ensures both energy pathways are utilized, improving carbohydrate use and performance.
Additional Ingredients in Standard Beta Fuel Gel
Standard SiS Beta Fuel gels include other components for texture, stability, and taste.
- Water: The base for the gel.
- Flavourings: Natural flavours to enhance taste.
- Acidity Regulators: Citric acid and sodium citrate to regulate pH and minimize stomach upset.
- Gelling Agents: Gellan gum and xanthan gum create the gel's texture.
- Preservatives: Sodium benzoate and potassium sorbate extend shelf life.
- Sodium Chloride: Helps replace electrolytes lost through sweat.
The Beta Fuel + Electrolyte Formula
This version of Beta Fuel includes higher levels of electrolytes, particularly sodium chloride, to support hydration during long or hot events.
The Beta Fuel + Nootropics Formula
Designed to support cognitive function during endurance activities, this gel contains:
- Caffeine: For concentration and reduced perceived effort.
- L-Theanine: To enhance alertness and mitigate caffeine jitters.
- Cognizin® Citicoline: Aids in information processing and focus.
- L-Taurine: An amino acid linked to improved endurance.
Beta Fuel vs. Other SiS Products: A Comparison
| Feature | SiS Beta Fuel Gel | SiS GO Isotonic Energy Gel |
|---|---|---|

How SiS Beta Fuel's Ingredients Enhance Performance
The 1:0.8 maltodextrin-to-fructose ratio in SiS Beta Fuel allows for higher carbohydrate absorption rates (up to 120g per hour) compared to the typical 60g limit with single-source carbohydrates. This provides more energy for muscles and organs, leading to enhanced performance, power output, and reduced gastric distress. Variations with nootropics further support mental focus. The availability in gels, powders, and chews helps prevent flavour fatigue and digestive issues. More information is available on the Science in Sport website.
Conclusion
The ingredients in SiS Beta Fuel provide a scientifically advanced fuelling strategy for endurance athletes. The dual-source 1:0.8 carbohydrate blend is efficiently absorbed and helps minimize digestive issues. With options including electrolytes and nootropics, the Beta Fuel range offers a comprehensive solution for optimizing performance during long-duration activities.
