Is Sparkling Water Healthy? What the Science Says

Sparkling water has exploded in popularity over the last decade — and for good reason. But with so many claims floating around (pun intended), it's worth looking at what the science actually says about drinking carbonated water regularly.

What Is Sparkling Water?

Sparkling water is simply water that has been infused with carbon dioxide (CO2) under pressure, creating those satisfying bubbles. It comes in several forms: plain sparkling water, mineral water, and flavored sparkling water. Home carbonation systems like Fizzit let you make your own fresh sparkling water on demand — without the plastic waste of store-bought bottles.

Is Sparkling Water as Hydrating as Still Water?

Yes. Multiple studies have confirmed that sparkling water hydrates just as effectively as still water. The carbonation does not reduce its hydrating properties. So if you find it easier to drink your daily water quota when it's bubbly, that's a genuine win for your health.

Does Sparkling Water Damage Your Teeth?

This is the most common concern — and the answer is: plain sparkling water is far less harmful than soda or juice. Carbonation does make water slightly acidic (pH around 3–4), but plain sparkling water without added citric acid or sugar has minimal erosive effect on enamel. A 2016 study in the Journal of the American Dental Association found that sparkling water was 100 times less damaging to teeth than soda. The key is to avoid flavored sparkling waters with added citric acid, and don't sip it constantly throughout the day.

Is Sparkling Water Good for Digestion?

For many people, yes. Research suggests that sparkling water can help relieve indigestion and constipation. One study found that people who drank sparkling water reported significantly less indigestion and constipation compared to those who drank still water. The carbonation appears to stimulate the nerves responsible for swallowing, which can ease digestive discomfort.

Does Sparkling Water Affect Bone Density?

This myth likely stems from studies on cola drinks, which contain phosphoric acid that can leach calcium from bones. Plain sparkling water contains no phosphoric acid and has not been shown to affect bone density. In fact, some mineral sparkling waters are rich in calcium and magnesium, which support bone health.

Can Sparkling Water Help You Drink Less Soda?

Absolutely — and this is one of the biggest health benefits. Many people use sparkling water as a satisfying substitute for soda, dramatically reducing their sugar and calorie intake. With a home carbonation system, you can enjoy fresh, customizable sparkling water without the sugar, artificial sweeteners, or preservatives found in most sodas.

The Bottom Line

Plain sparkling water is a healthy, hydrating choice for most people. It's a smart swap for soda, supports digestion, and doesn't meaningfully harm your teeth when consumed in moderation. Making your own at home with a system like Fizzit gives you full control over what goes into your water — and cuts down on single-use plastic bottles at the same time.
