Perrier and San Pellegrino are popular brands of sparkling water. Both types have a number of other mineral components and are slightly acidic. Neither of the two are acidic enough to cause dehydration, or any potentially negative impacts.

Is Perrier good for hydration?

Sparkling water hydrates you just as much as regular water. Thus, it contributes to your daily water intake. In fact, its fizziness may even enhance its hydrating effects for some people.

Why is Perrier water bad for you?

Since sparkling water contains CO2 gas, the bubbles in this fizzy drink can cause burping, bloating and other gas symptoms. Some sparkling water brands may also contain artificial sweeteners like sucralose, warns Dr. Ghouri, which may cause diarrhea and even alter your gut microbiome.
