Does Sparkling Water Hydrate You?

Quick answer: Yes. Sparkling water hydrates you essentially as well as still water. The carbonation is just dissolved carbon dioxide — it does not pull water out of your body or cancel out the hydration.

The hydration myth

A common belief is that fizzy water "dehydrates" you. It does not. Sparkling water is still water plus carbon dioxide, and the water content hydrates you the same way. Studies comparing carbonated and non-carbonated water find no meaningful difference in hydration.

Why sparkling water can help you drink more

For many people the bubbles and tangy taste make water more enjoyable, so they reach for it instead of soda and end up drinking more total fluid. In that sense, sparkling water can improve your hydration habits.

The small caveats

Plain sparkling water (no sugar, no added acids) is the healthy version. Skip sweetened sparkling drinks if hydration is the goal. The carbonation is mildly acidic, so if you are prone to enamel wear, enjoy it with meals. Some people find a lot of fizz bloating — that is comfort, not hydration.
