Is Sparkling Water as Hydrating as Regular Water?

As the sparkling water trend really takes off, people are wondering, is sparkling water as hydrating as regular water?

The CDC recommends sparkling water as a healthier alternative to soda and other high-calorie beverages but with water in the name, we can’t help but wonder if it’s actually worth its weight in… well, water.

Considering just the unflavored sparkling water, for argument’s sake, a number of myths have been floating around the internet on the subject and its negative side effects.

The first myth is that sparkling water destroys tooth enamel. But the pH level of sparkling water is 5, which is not low enough to erode tooth enamel. But reading the label is important here because if your sparkling beverage of choice contains citric acid, added flavors, and/or sugars, this is where tooth enamel takes a hit.

The second myth is a little more specific, where people believe that sparkling water leaches calcium from bones, leading to osteoporosis. While studies have shown an association between decreased bone mineral density and soda consumption, but this study had to do with cola specifically. Another study had one group of participants drink 1 liter of carbonated water a day and another group drink 1 liter of regular water a day for 8 weeks and no difference was detected in bone density loss.

The final myth: sparkling water is less hydrating than regular water. Good news! This is not true. The American Journal of Clinical Nutrition compared still, sparkling, and other popular drinks, finding there was no difference in terms of hydration.

The USDA does recommend sparkling water as a good alternative to sugary drinks as a good way to reduce your risk for obesity. So go ahead, crack open that La Croix this summer and quench your thirst—it’s hydrating and a healthier option that doesn’t hurt your bones or teeth.
