Plain, unsweetened sparkling water is a healthy beverage choice that provides hydration without added sugar, calories, or artificial ingredients. However, the healthiest option depends on your specific health goals, sensitivities, and preferences. Some sparkling waters offer additional benefits from naturally occurring minerals, while others can be problematic due to additives or contaminants. Making an informed choice requires a careful look at the label and an understanding of different types of carbonated beverages.
Decoding the Label: What to Look For
To determine if a sparkling water is a healthy choice, you must look beyond the packaging and examine the ingredients list and nutritional information. The following are key factors to consider:
Absence of Added Sweeteners
This is perhaps the most important health consideration. Many flavored sparkling waters contain artificial sweeteners like aspartame or sucralose, or added sugars and juices. These can contribute to digestive issues and other health problems over time. The healthiest sparkling water contains no sweeteners at all, relying on natural fruit essences or real fruit juice for flavor.
Mineral Content and Source
Some sparkling waters, known as mineral water, are naturally carbonated from a spring or well and contain naturally occurring minerals like calcium, magnesium, and sodium. These can have health benefits, such as contributing to bone health. The mineral profile, often measured as Total Dissolved Solids (TDS), affects the taste and mouthfeel. If you are on a sodium-restricted diet, be mindful of brands with higher mineral content.
Avoiding Potential Contaminants
Recent reports have raised concerns about the presence of PFAS (per- and polyfluoroalkyl substances) in some bottled water brands. These are synthetic chemicals that can accumulate in the body and are linked to various health issues. Some brands have worked to reduce their levels, but consumer awareness remains important. Opting for brands that have tested low for PFAS or filtering your own water at home are ways to mitigate this risk.
The Flavored Water Acidity Factor
While plain carbonated water has a minimally erosive effect on tooth enamel, the addition of flavors—especially citrus—can lower the pH and increase its acidity. Repeated exposure to these acidic beverages could potentially weaken enamel over time. To minimize this risk, dentists recommend drinking flavored varieties in moderation, preferably with a meal, and using a straw to reduce contact with teeth.
Comparison of Popular Sparkling Water Brands

|---|---|---|---|---|
| Spindrift | Seltzer with real fruit juice | Only from real fruit | Many fruit-based | Natural flavor, minimal processing, and fruit sweetness. |
| Waterloo | Seltzer with fruit essences | None | Bold fruit flavors | Zero sweeteners, zero sodium, and accurate flavors. |
| Topo Chico | Sparkling Mineral Water | None (unflavored) | Some with essences | High carbonation and mineral content, but historically had higher PFAS levels. |
| Gerolsteiner | Sparkling Mineral Water | None | Unflavored | Naturally rich in minerals like magnesium and calcium. |
| LaCroix | Seltzer with natural essences | None | Wide variety | Zero sugar and low sodium, but tested positive for PFAS in some reports. |

How to Find Your Healthiest Sparkling Water
The most straightforward way to ensure your sparkling water is healthy is to choose plain, unflavored options with a minimal ingredients list. For those who prefer flavor, brands like Spindrift and Waterloo offer excellent sugar-free options. However, the ultimate healthiest choice may be homemade. A home carbonation system like a SodaStream allows you to carbonate your own water, providing complete control over the source and flavorings. You can then add fresh fruit slices, herbs, or a splash of 100% fruit juice to create a beverage that is perfectly customized and free of any unwanted additives. A comprehensive guide to selecting and carbonating water at home is available through the Water Quality Association's resources on water quality and filtration.
Conclusion
The healthiest sparkling water is plain, unsweetened carbonated water, ideally from a trusted, uncontaminated source. For many, this simple option is a satisfying and calorie-free way to stay hydrated. If you prefer flavored varieties, focus on brands that use natural essences or real fruit juice and avoid artificial sweeteners and high sodium content. While sparkling water offers a refreshing alternative to sugary sodas, being mindful of potential issues like dental erosion and PFAS contamination is wise. By reading labels carefully and considering your own health needs, you can easily select the fizzy beverage that is best for you.
How to Choose the Healthiest Sparkling Water
Prioritize Minimal Ingredients
Look for a list with just "carbonated water," or "mineral water and carbon dioxide," to avoid sweeteners and artificial flavors.
Favor Natural Over Artificial
Choose brands that use fruit essence or real juice for flavor, rather than artificial or zero-calorie sweeteners.
Know Your Source
Be aware of the water source; some mineral waters provide beneficial electrolytes, but check the sodium levels if you have concerns.
Consider DIY Options
Making your own sparkling water at home with a carbonator ensures control over the water source and ingredients, eliminating packaging waste.
Drink Flavored Waters Moderately
Acidic flavors can impact dental health, so save them for meals and consider drinking them through a straw to protect your enamel.
Be Aware of Contaminants
Check brand reputations regarding potential contaminants like PFAS and consider options with low or undetected levels.
