Although theres not a huge amount of research on this yet, several studies have shown that, yes, sparkling water hydrates you just as well as still water (and nutritionists tend to agree). This makes sense, considering that carbonated water is just regular water infused with bubbly carbon gas.
Which is better for you carbonated water or regular water?
Current evidence suggests that sparkling water hydrates your body just as well as regular water. Admittedly, though, theres limited research on the topic. Theres certainly nothing to suggest that the added carbon dioxide prevents your body from absorbing sparkling water any differently than regular water.
Can you drink carbonated water everyday?
While there are some mixed opinions to be found, according to the American Dental Association, drinking sparkling water every day is generally fine even though its more acidic than still water. Best to stick to the other options, then, such as plain or berry-flavored seltzers.
