Understanding the SiS Beta Gel Range
Science in Sport (SiS) offers a range of energy gels, and the answer to whether they contain electrolytes depends on the specific product. The crucial point of clarification is the distinction between the standard SiS Beta Fuel Energy Gel and the SiS Beta Fuel + Electrolyte Gel. While both are designed for endurance performance, their formulations cater to different needs during prolonged exercise.
The standard Beta Fuel Energy Gel provides a high dose of carbohydrates, with 40g per serving, using an optimized 1:0.8 ratio of maltodextrin to fructose for efficient energy absorption. Its primary purpose is to fuel the body with energy, but it contains a minimal amount of electrolytes, primarily as a stabilizer, not for rehydration. In contrast, the Beta Fuel + Electrolyte Gel delivers the same 40g of carbohydrates but with significant added electrolytes, including 200mg of sodium and 300mg of chloride per 60ml serving, to support fluid balance and replace minerals lost through sweat.
The Role of Electrolytes in Endurance Sports
Electrolytes such as sodium and chloride are vital for regulating nerve and muscle function, and maintaining proper hydration. During prolonged exercise, especially in warm conditions, athletes lose these minerals through sweat. Failure to replace them can lead to dehydration, muscle cramps, and a decline in performance.
- Sodium: Helps with fluid balance and triggers thirst. The body loses a significant amount of sodium through sweat, making its replacement critical for preventing hyponatremia (low blood sodium).
- Chloride: Works alongside sodium to maintain fluid and electrolyte balance in the body.
How to Choose the Right SiS Gel
Selecting the correct gel depends on the duration, intensity, and conditions of your exercise. For shorter sessions or cooler weather, the standard Beta Fuel gel might be sufficient if your focus is primarily on carbohydrate intake. However, for any exercise lasting longer than two hours, or when exercising in hot and humid conditions, the Beta Fuel + Electrolyte gel becomes the more appropriate choice.
Comparison Table: SiS Beta Fuel vs. Beta Fuel + Electrolyte
| Feature | SiS Beta Fuel Energy Gel | SiS Beta Fuel + Electrolyte Gel |
|---|---|---|
| Carbohydrate Content | 40g (Maltodextrin/Fructose 1:0.8) | 40g (Maltodextrin/Fructose 1:0.8) |
| Electrolyte Content | Minimal (primarily Sodium Chloride) | 200mg Sodium, 300mg Chloride |
| Primary Use Case | Fuelling for endurance exercise (>2 hours) where carbohydrate is the main priority. | Fuelling and hydration for endurance exercise, especially in hot conditions or for high sweat-rate athletes. |
| Gut Comfort | Optimized formula to minimize gastrointestinal discomfort. | Also designed to be gentle on the stomach. |
| Packaging Size | 60ml | 60ml |
Integrating Electrolytes into Your Fuelling Strategy
For endurance athletes, a comprehensive fuelling strategy often involves more than just gels. Products like SiS's GO Electrolyte drinks or Hydro tablets can also be used in combination with Beta Fuel gels to achieve optimal energy and hydration. For instance, you could use a standard Beta Fuel gel for energy and supplement with a hydration tablet in your water bottle for additional electrolytes, allowing for a more tailored approach.
The dual-action nature of the Beta Fuel + Electrolyte gel simplifies this process, combining both needs into a single, convenient product. This is particularly useful during high-intensity sections of a race or when space for carrying multiple products is limited. Ultimately, the best strategy is to train with both products to determine which one works best for your body under different conditions.
Conclusion
To definitively answer the question, some SiS Beta gels, specifically the Beta Fuel + Electrolyte formulation, do have electrolytes, while the standard Beta Fuel Energy Gel does not contain them in significant amounts for rehydration. This clear distinction is key for athletes planning their nutrition. For exercises lasting over two hours or involving heavy sweating, the Beta Fuel + Electrolyte gel is the scientifically supported choice to maintain energy, prevent dehydration, and optimize performance. For shorter, less intense sessions, the standard Beta Fuel gel remains an excellent option for a concentrated carbohydrate boost.

Key Takeaways
- Not All Beta Gels are the Same: Only the SiS Beta Fuel + Electrolyte Gel contains significant added electrolytes.
- Standard Beta Gel for Carbs: The standard SiS Beta Fuel gel focuses on a high concentration of 40g carbohydrates for energy, not hydration.
- Electrolytes for Hydration: The Beta Fuel + Electrolyte version includes 200mg sodium and 300mg chloride per serving to replace sweat loss.
- Match Gel to Conditions: Use the electrolyte version for prolonged exercise (>2 hours) or in hot weather, and the standard version for shorter sessions.
- Strategy is Key: You can combine the standard Beta Fuel gel with other electrolyte products, like tablets or drinks, for a more customized fuelling plan.
