A practical choice for cyclists, runners and active customers who want high-sodium, low-calorie hydration for shorter or sweat-heavy sessions.
SIS GO Hydro is an effervescent electrolyte tablet designed for straightforward hydration before, during or after exercise. Add one Berry tablet to 500 ml of water, allow it to dissolve fully and you have a convenient drink containing 789 mg of essential electrolytes and 870 mg of sodium per serving.
The formula combines sodium, calcium, magnesium and potassium with vitamins B1, B2 and B6. At just 7 kcal per tablet, it suits shorter sessions where you need fluids and electrolytes but not a substantial carbohydrate intake. The tablet format is easy to keep in a kit bag, bottle cage storage or gym bag, while the Berry flavour offers a light, refreshing alternative to plain water.
This is a particularly useful option for warm conditions and heavier sweaters, but its high sodium content will not suit everyone. If you need to limit sodium, check the product’s suitability for your needs before use. For longer sessions where you also need energy, pair your hydration with a separate carbohydrate product.
