What exactly are SiS electrolytes?
SiS, or Science in Sport, is a leading sports nutrition brand known for its science-backed products. SiS electrolytes are formulations of essential minerals, predominantly sodium, potassium, calcium, and magnesium, designed to support optimal hydration. The brand offers different products tailored for various athletic needs: the low-calorie GO Hydro tablets for pure hydration and the GO Electrolyte powder, which combines both energy-providing carbohydrates and hydrating electrolytes. These products are engineered to be easily digestible and rapidly absorbed, ensuring that athletes can replenish what they lose through sweat to avoid dehydration, which is a major cause of fatigue and decreased performance.
The crucial role of electrolytes in the body
Electrolytes are essential minerals that carry an electric charge when dissolved in body fluids like sweat and blood. They are vital for numerous physiological functions, including muscle contraction, nerve signal transmission, and maintaining the body's fluid balance. During physical exercise, especially prolonged or intense sessions, these minerals are lost through sweat. Without adequate replacement, this can lead to electrolyte imbalances, causing symptoms like muscle cramps, fatigue, dizziness, and decreased performance. SiS electrolytes address this by providing a targeted and effective way to replace these lost minerals.
Key Formulations: GO Hydro vs. GO Electrolyte
SiS has developed different formulations to meet the specific needs of athletes depending on the duration and intensity of their activity.
GO Hydro Tablets These effervescent tablets are the go-to for low-calorie hydration. Designed for use before and during shorter training sessions (typically under 60 minutes) or for general rehydration where energy is not the priority, GO Hydro tablets dissolve in water to provide a high-electrolyte drink with minimal calories. This formulation is especially beneficial for athletes managing their calorie intake or those exercising in warm conditions where sweat loss is high, but energy expenditure is moderate. GO Hydro was originally developed for the British Sailing team at the 2008 Beijing Olympics.
GO Electrolyte Powder For longer, more intense endurance activities like marathons or triathlons, athletes need both hydration and energy. GO Electrolyte powder combines a rapid supply of easily digestible carbohydrates with a blend of essential electrolytes. This dual-action formula tackles two primary causes of fatigue—carbohydrate depletion and dehydration—simultaneously. The powder mixes into a solution with a specific carbohydrate concentration (6% solution) to aid rapid fluid absorption and keep muscles fuelled.
GO Energy + Electrolyte Gels For a convenient, on-the-go option, SiS offers gels that combine carbohydrates with electrolytes. These are particularly useful during high-intensity exercise or in hot weather, when sweat rates are high and an athlete needs a quick hit of both energy and electrolytes.

The scientific advantages of SiS electrolytes
The effectiveness of SiS electrolytes is rooted in their evidence-based formulation. The company has a long history of collaborating with elite athletes and research institutions to develop its products. A key scientific principle behind SiS GO Hydro is its specific sodium concentration (30mmol/L), which has been scientifically shown to provide superior hydration compared to water alone by promoting fluid absorption and retention. All SiS products are also Informed Sport accredited, meaning every batch is tested for banned substances, providing a crucial assurance of quality and safety for competitive athletes.
How to use SiS electrolytes effectively
To get the most out of your SiS products, follow the recommended usage guidelines.
Using GO Hydro tablets
- Dissolve one tablet in 500ml of water.
- Consume 500ml of the drink 3-4 hours before an event, with an additional 250-500ml in the hour before starting.
- During shorter exercise sessions (<60 minutes) or in very hot weather, consume 500ml per hour.
- Do not exceed 4 tablets per day.
Using GO Electrolyte powder
- Add 40g (two scoops) of powder to 500ml of water in a sports bottle and shake well.
- Drink 500ml of the mixture every 45-60 minutes during endurance exercise.
- Consume within 24 hours of preparation.
Conclusion
SiS electrolytes are a scientifically formulated and effective solution for preventing dehydration and combating fatigue during physical activity. By offering tailored products like the low-calorie GO Hydro tablets and the carbohydrate-plus-electrolyte GO Electrolyte powder, SiS provides athletes with the tools they need for optimal hydration and sustained performance. Whether you're an endurance athlete requiring energy alongside hydration or engaging in shorter, more intense workouts, understanding the different SiS products allows you to choose the best option to meet your specific needs and stay at the top of your game. The company's commitment to research and Informed Sport accreditation provides athletes with a trusted and high-quality solution for their sports nutrition regimen.
