Understanding the Different Types of SiS Gels
Science in Sport (SiS) is a popular brand among endurance athletes, known for its range of energy gels. However, not all SiS gels are created equal, especially when it comes to hydration. The two primary types of concern for this topic are the classic GO Isotonic Energy Gel and the GO Energy + Electrolyte Gel. While both provide carbohydrates for energy, only the electrolyte-enhanced version is specifically formulated to assist with hydration.
The Pure Energy Focus: SiS GO Isotonic Energy Gels
The original SiS GO Isotonic Energy Gel is renowned for being the world's first true isotonic gel. The term "isotonic" refers to the gel's concentration, which is similar to that of the human body's fluids. This formulation allows the gel to be absorbed quickly from the stomach and into the bloodstream without the need for additional water, which can help minimize the risk of bloating and other gastrointestinal distress during exercise.
What this means for hydration is important: The primary function of the isotonic gel is to deliver 22 grams of easily digestible carbohydrates to working muscles to prevent fatigue,. Because its electrolyte content is minimal, it does not significantly contribute to replacing the fluids and minerals lost through sweat. For this reason, relying on the standard isotonic gel alone will not meet your hydration requirements, especially during longer or more intense sessions. You must consume separate fluids, like water or a dedicated electrolyte drink, to stay properly hydrated.
The Hydration-Boosting Formula: SiS GO Energy + Electrolyte Gels
In contrast, the SiS GO Energy + Electrolyte Gel is designed to address both energy and hydration needs simultaneously. These gels contain the standard 22g of fast-acting carbohydrates but are fortified with key electrolytes, including sodium, potassium, and magnesium,. These minerals are essential for maintaining fluid balance, and their loss through sweat is a major contributor to dehydration and performance decline.
By supplementing with electrolytes, this gel helps the body retain and absorb fluid more effectively. This makes it a much better choice for exercising in hot conditions or during long sessions where sweat rates are high,. While this gel does provide hydration support, it is not a complete replacement for fluid intake. It is a supplement to your overall hydration strategy, which should still include plain water or other sports drinks as appropriate.
When to Choose Your Gel
Choosing the right gel depends entirely on your training conditions and goals. For a standard, moderate-intensity workout where you can easily access and drink water, the isotonic gel might be sufficient for a quick energy boost. However, if you are planning a long endurance event, particularly in warm weather, the electrolyte gel becomes a more strategic choice.
Combining Gels and Fluids for Optimal Performance
Many athletes use a combination of products to meet their fueling and hydration needs. For exercise lasting over 90 minutes, a recommended approach is to consume approximately 60g of carbohydrates per hour. This can involve using a mix of isotonic gels and electrolyte gels. For example, you might have two isotonic gels and one electrolyte gel per hour, adjusting based on your sweat rate and the ambient temperature. Just remember that even with electrolyte gels, a suitable fluid intake alongside them is necessary to prevent over-consuming electrolytes and compromising hydration.
Comparison: SiS Isotonic Energy Gel vs. SiS Energy + Electrolyte Gel
| Feature | SiS GO Isotonic Energy Gel | SiS GO Energy + Electrolyte Gel |
|---|---|---|
| Primary Purpose | Fast carbohydrate energy delivery. | Fast energy + electrolyte replenishment. |
| Hydration Support | Minimal, does not replace lost fluids or electrolytes. | Provides key electrolytes to aid fluid balance and retention. |
| Electrolyte Content | Very low. | Contains sodium, potassium, and magnesium. |
| Need for Water | Not necessary for digestion, but still require regular water intake for hydration,. | Best used alongside water for comprehensive hydration, especially in high-sweat situations. |
| Best For | High-intensity exercise or shorter events where energy is the main concern. | Long or warm weather exercise where high sweat rates increase electrolyte loss. |
Conclusion
In summary, whether a SiS gel hydrates you depends entirely on the specific product. The standard SiS GO Isotonic Energy Gels are designed for energy delivery and are not a significant source of hydration. Conversely, the SiS GO Energy + Electrolyte Gels are formulated with added minerals to help replace what is lost in sweat, thereby actively supporting hydration. For endurance athletes, incorporating electrolyte gels, especially during long, hot sessions, can be a crucial part of a balanced nutritional strategy. However, these gels should always be used in conjunction with a proper fluid intake to ensure optimal performance and prevent dehydration.
