Sparkling water, known for its refreshing fizz, is a popular alternative to still water — but is it just as hydrating? Dietitians confirm that sparkling water, also called carbonated or seltzer water, provides the same hydration benefits as still water because both are essentially H2O. Research supports this, showing that carbonation doesn’t interfere with hydration, making sparkling water a solid option for reaching daily water intake goals.

Although both sparkling and still water are equally hydrating, they each provide a different experience. Sparkling water’s carbonation can make it feel more filling, and it may sometimes lead to temporary bloating or gas. For those who find plain water less appealing, the bubbles in sparkling water might encourage more regular hydration. Sparkling water is also an excellent soda alternative, helping people cut back on sugar without sacrificing the refreshing fizz they enjoy.

When choosing sparkling water, the healthiest options are plain sparkling or mineral water without any added sugars or artificial sweeteners. If you prefer flavored sparkling water, experts recommend selecting naturally flavored seltzers with as few additives as possible.
