Why Choose SiS GO Hydro Tablets?

SiS GO Hydro Tablets provide electrolytes in a compact effervescent tablet format. Add one tablet to 500ml of water to prepare a low-carbohydrate hydration drink that can be used during training, competition or everyday activity.

The standard HYDRO formula provides sodium together with potassium, calcium and magnesium, plus vitamins B1, B2 and B6. Science in Sport lists approximately 789mg of essential electrolytes per serving.

Because GO Hydro Tablets contain very little carbohydrate, they can be used when your priority is electrolyte hydration rather than carbohydrate fuelling. If you need carbohydrate during longer or harder endurance sessions, carbohydrate can be taken separately through gels, drinks, bars or other sports nutrition products.

Cola + Caffeine is the caffeinated option in the range and provides 75mg of caffeine per tablet.
