The Core Dual-Source Carbohydrate System
SiS Beta Fuel Gel features a dual-source carbohydrate blend, using maltodextrin and fructose in a 1:0.8 ratio. This formulation is designed to provide 40 grams of carbohydrates per 60ml gel.
Maltodextrin: The Rapid Fuel Source
Maltodextrin, derived from maize, is a fast-acting glucose source absorbed via the SGLT1 transporter protein, providing quick energy to muscles and helping prevent glycogen depletion.
Fructose: The Sustained Energy Component
Fructose uses a separate transporter (GLUT5) and is processed by the liver, offering a slower energy release. {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-gel-pack} {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-electrolyte-gel} {Link: Science in Sport https://www.scienceinsport.com/eu/beta-fuel-plus-nootropics-gels-sis}
SiS offers variations of the Beta Fuel gel with specific added ingredients:
Beta Fuel + Electrolyte Gel contains increased levels of sodium chloride for hydration, especially in hot conditions. It also includes flavouring and gelling agents.
Beta Fuel + Nootropics Gel includes L-Taurine, Cognizin® Citicoline, Caffeine Anhydrous, and L-Theanine to support endurance, cognitive function, and mental alertness.
Comparison Table: SiS Beta Fuel vs. SiS Go Isotonic
| Feature | SiS Beta Fuel Gel | SiS Go Isotonic Energy Gel |
|---|---|---|
| Carbs per 60ml Gel | 40g | 22g |
| Carbohydrate Ratio | 1:0.8 (Maltodextrin:Fructose) | N/A (primarily maltodextrin) |
| Isotonic | No (thicker consistency) | Yes (same concentration as bodily fluids) |
| Best Use Case | Endurance exercise > 2 hours, high fuelling needs | Shorter sessions, beginners, sensitive stomachs |
How SiS Beta Fuel Gel Ingredients Optimize Performance
The 1:0.8 maltodextrin and fructose ratio in SiS Beta Fuel is designed to maximize carbohydrate absorption, allowing athletes to consume 80–120g per hour with reduced gastrointestinal distress compared to single-source gels. This supports sustained energy, power output, and minimizes stomach problems during long events. The Informed Sport certification ensures the product is free from banned substances.
Conclusion: The Formula Behind Long-Lasting Fuel
The ingredients in SiS Beta Fuel Gel form a scientifically designed formula for endurance performance. The dual-source carbohydrate system is key to maximizing energy delivery and minimizing stomach upset. This formulation is fundamental for athletes undertaking efforts lasting longer than two hours. {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-gel-pack} {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-electrolyte-gel} {Link: Science in Sport https://www.scienceinsport.com/eu/beta-fuel-plus-nootropics-gels-sis}

Key Takeaways
- Dual Carbs for Peak Efficiency: SiS Beta Fuel uses a 1:0.8 ratio of maltodextrin and fructose to maximize carbohydrate absorption and support sustained energy for long-duration activities.
- Minimized GI Issues: The specific carbohydrate ratio and pH-regulating agents are designed to reduce the risk of bloating and stomach distress during prolonged exercise.
- High-Dose Carbohydrates: Each 60ml gel delivers a concentrated 40 grams of carbohydrates, helping athletes meet high hourly fuelling targets with fewer gels.
- Targeted Variations: The product line includes a Beta Fuel + Electrolyte gel for enhanced hydration and a Beta Fuel + Nootropics gel that includes caffeine for a mental boost.
- Certified Clean: Like all SiS products, Beta Fuel gels are certified under the Informed Sport program, ensuring they are free of banned substances.
- Supporting Ingredients: Common additives like gellan gum and xanthan gum create an easily digestible texture, while citric acid and sodium citrate regulate acidity for gut comfort.
FAQs
Q: What are the main ingredients in SiS Beta Fuel Gel? A: The primary ingredients are water, maltodextrin (from maize), and fructose, formulated in a 1:0.8 ratio, along with flavourings, acidity regulators, gelling agents, preservatives, and sodium chloride. {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-gel-pack} {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-electrolyte-gel} {Link: Science in Sport https://www.scienceinsport.com/eu/beta-fuel-plus-nootropics-gels-sis}
Q: Why does SiS use a 1:0.8 maltodextrin to fructose ratio? A: The 1:0.8 ratio is scientifically optimized to use two different absorption pathways for glucose (from maltodextrin) and fructose. {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-gel-pack} {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-electrolyte-gel} {Link: Science in Sport https://www.scienceinsport.com/eu/beta-fuel-plus-nootropics-gels-sis}
Q: Is SiS Beta Fuel Gel suitable for vegans? A: Yes, the standard SiS Beta Fuel Gel is made with vegan-friendly ingredients and contains no animal-derived products.
Q: Do you need to consume water with SiS Beta Fuel Gel? A: While SiS Beta Fuel is more concentrated than isotonic gels, consuming water is always recommended during exercise, especially when taking in multiple gels per hour, to aid absorption and hydration.
Q: How does the Beta Fuel gel minimize stomach issues during long events? A: The precise 1:0.8 carbohydrate ratio prevents the overwhelming of a single intestinal transporter, which minimizes gastric fullness and discomfort. The inclusion of acidity regulators also aids with overall gut tolerance.
Q: What is the difference between SiS Beta Fuel and SiS Go Isotonic gels? A: SiS Beta Fuel gels contain a higher concentration of carbohydrates (40g) and use a dual-carb ratio optimized for longer efforts. {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-gel-pack} {Link: Science in Sport https://www.scienceinsport.com/beta-fuel-electrolyte-gel} {Link: Science in Sport https://www.scienceinsport.com/eu/beta-fuel-plus-nootropics-gels-sis}
Q: Does SiS Beta Fuel gel come in other versions with added ingredients?
