Electrolytes explained
Electrolytes — calcium, magnesium, sodium, potassium and bicarbonate — regulate hydration, muscle function and pH balance. Mineral water delivers them naturally.
Best Sparkling Water for Electrolytes
Naturally carbonated mineral waters can be excellent electrolyte sources — no added ingredients, no sugar, no calories. Here are the best picks.

Hydration benefits
Plain water rehydrates; mineral water rehydrates AND restores the electrolytes lost in sweat. Naturally carbonated options add a satisfying mouthfeel that many find easier to drink in volume.
Best overall picks
- 1. Gerolsteiner — best balance of Ca, Mg and bicarbonate
- 2. Borjomi — top for bicarbonate and sodium replacement (avoid on low-sodium diets)

- 4. San Pellegrino — most accessible mineral-rich choice
Frequently asked questions
Which sparkling water has the most electrolytes?
Gerolsteiner offers the best all-around balance; Borjomi delivers the highest bicarbonate and sodium.
Can sparkling water replace sports drinks?
For low-to-moderate exercise, mineral water is an excellent alternative — without sugar or artificial ingredients. For prolonged endurance, you may still need additional sodium and carbs.
Is sparkling water as hydrating as still water?
Yes — research consistently shows carbonation does not impair hydration.
