SiS GO Hydro Electrolyte Tubes provide a convenient way to prepare a low-calorie electrolyte drink for exercise and everyday hydration. The effervescent tablets dissolve in water to supply sodium and other key minerals, making them useful during sweaty training sessions, warmer conditions and activities where a carbohydrate-heavy sports drink is not required.

Each tube contains 20 tablets and is designed for straightforward bottle preparation: dissolve one tablet in 500ml of water. A variety of flavours is available, including a separate Cola + Caffeine formulation. The compact tube format is practical for gym bags, running kit and travel, while keeping hydration distinct from your energy-fuelling strategy.
