Sparkling mineral water is an Aussie fridge staple. It has minerals in it, so it's fair to ask: is mineral water basically an electrolyte drink? And if you're choosing between the two after a workout or on a hot day, which one should you reach for?
Here's how they compare.
What's in mineral water
Mineral water comes from underground sources and naturally contains minerals such as calcium, magnesium, sodium and bicarbonate. The exact mix depends on the source, so it varies a lot between brands. Some have barely any sodium, others have a little more. Sparkling mineral water is the same idea with bubbles, either natural or added.
What's in an electrolyte drink
An electrolyte drink is designed to replace what you lose in sweat. The main electrolyte you lose is sodium, followed by potassium. Electrolyte drinks are formulated to contain a meaningful amount of these, usually far more sodium than mineral water, along with flavour to make it easy to drink.
The key difference: sodium
Mineral water's minerals are a nice bonus, but in most cases there isn't much sodium. If you've had a big sweat, it's sodium you're mainly short on, and sodium plays a role in how your body holds on to the fluid you drink. That's where an electrolyte drink earns its place.
When mineral water is enough
- Everyday hydration at your desk or with meals.
- Short, easy exercise on a mild day.
- When you want something sparkling and refreshing with no flavour.
When an electrolyte drink makes more sense
- After long or very sweaty sessions.
- Hot days, outdoor work and summer sport. See electrolytes in hot weather.
- Hot yoga, hot Pilates and sauna sessions.
- Long shifts, travel and back to back training days.
Sparkling electrolyte drinks: the middle ground
If you love the fizz of mineral water but want real electrolytes, a lightly sparkling natural hydration drink gives you both. Uthrive is lightly sparkling, with sodium from certified organic Lake Deborah salt and potassium alongside, plus a splash of real fruit for flavour. It's low sugar with no added sugar and no artificial sweeteners. Think of it as the refreshment of sparkling water with electrolytes from real salt. More in sparkling electrolyte drinks.

Frequently asked questions
Is mineral water an electrolyte drink?
It contains some minerals, but usually not enough sodium to replace what you lose in a big sweat. It's great for everyday drinking.
Is sparkling water as hydrating as still water?
For most people, yes. Bubbles don't stop water hydrating you.
Can I add salt to mineral water?
Some people do. A ready-made drink just makes it easier and tastier, with a known amount of electrolytes.
Is Uthrive just flavoured mineral water?
No. Uthrive is a natural hydration drink made with real salt from Lake Deborah, potassium, real fruit and natural flavours. Full details in what's in Uthrive.
Which should I drink after the gym?
After a short, easy session, either works. After a sweaty one, a drink with electrolytes may suit you better. See our gym hydration guide.
