Understanding What Makes a Sparkling Water Healthy
Choosing the healthiest sparkling water isn't as simple as picking a can off the shelf. Multiple factors can impact a brand's health profile, from sourcing to processing. Understanding these criteria is the first step toward making an informed decision about what you drink.
The Ingredient Checklist
For the purest sparkling water, the ingredient list should be short and simple. Ideally, it contains only carbonated water. For flavored options, look for brands that use real fruit juice or natural fruit essences, avoiding added sugars, artificial sweeteners, or preservatives. Brands like Spindrift stand out by using real fruit, leading to a small amount of natural sugar but a more authentic flavor profile. In contrast, options like Waterloo utilize natural fruit essences to achieve zero calories and zero sugar. Reading labels is crucial, as the vague term 'natural flavors' can sometimes mask processed or less-desirable ingredients.
The PFAS Problem
One of the most concerning health factors in recent years has been the discovery of PFAS, or 'forever chemicals,' in some bottled water products. PFAS are persistent chemicals linked to a range of health issues. Independent lab testing is the only way to confirm a brand's PFAS levels, and several brands have been named in reports, including Topo Chico and La Croix. Some brands, like Mountain Valley and Spindrift, have been noted for their lower PFAS levels or for using water filtered via reverse osmosis. When shopping, keeping these reports in mind is wise.
Mineral Content, Acidity, and Sodium
All sparkling waters are slightly acidic due to the carbonic acid formed when carbon dioxide is dissolved in water. However, some flavored options, especially those with citrus, can be considerably more acidic, potentially impacting dental enamel over time. Unflavored sparkling mineral waters tend to be less acidic. Mineral waters like San Pellegrino and Gerolsteiner contain naturally occurring minerals like calcium, magnesium, and bicarbonate, which can benefit health but may also contribute to higher sodium levels. For those on a low-sodium diet, brands like La Croix and Waterloo are sodium-free and often preferred.
Top Contenders for the Healthiest Sparkling Water
Mountain Valley Sparkling Water
Sourced from a protected spring in the Ouachita Mountains, Mountain Valley has been ranked for its purity and low PFAS levels. It is naturally carbonated and offers a clean, crisp taste that many prefer for its lack of a strong mineral flavor.
Spindrift Sparkling Water
For those who prefer a real, fruity flavor, Spindrift is a top choice. It uses actual squeezed fruit juice for flavoring, resulting in a product that tastes fresh and authentic. Spindrift also tests with low PFAS levels, making it a safe and delicious option.
Waterloo Sparkling Water
This brand is lauded for its bold, accurate flavors derived from natural fruit essences, with zero calories, zero sugar, and zero sodium. Waterloo is a reliable choice for vibrant taste without any unwanted additives.
San Pellegrino Sparkling Natural Mineral Water
As a mineral water, San Pellegrino is known for its effervescence and balanced mineral content. It has tested with very low PFAS levels, providing a classic and clean taste for those who appreciate natural minerals in their water.

Note: PFAS test results can vary over time. It's always a good idea to research the latest reports.
Brands to Approach with Caution (Due to PFAS Concerns)
In addition to general ingredient awareness, some brands have faced scrutiny over PFAS contamination in recent years. While many have made efforts to reduce or eliminate these chemicals, consumers should be mindful. According to a 2020 Consumer Reports study, Topo Chico showed high levels of PFAS, though they have since reformulated. Brands like Polar, Bubly, and Perrier also tested with detectable levels of these persistent chemicals. For consumers focused on minimizing chemical exposure, it is wise to research the latest testing results and consider alternatives with cleaner track records.
The DIY Option: Homemade Sparkling Water
For ultimate control over ingredients and sourcing, consider making your own sparkling water at home. A device like a SodaStream allows you to carbonate your own filtered tap water, eliminating packaging waste and providing a blank canvas for flavor. By starting with filtered water (ideally from a reverse osmosis filter that can remove PFAS), you can guarantee purity. Add fresh fruits, herbs, or a small amount of juice to create your own customized, healthy beverage. This method puts you in complete control and ensures the healthiest possible result.
Conclusion: Making the Best Choice for Your Health
There is no single "healthiest" brand, as the best choice depends on your priorities. For those seeking minimalist perfection, brands like Mountain Valley offer simple, natural purity. If authentic fruit flavor is your goal, Spindrift's real fruit juice is a standout. If you want a flavorful, zero-calorie, zero-sodium drink without contaminants, Waterloo and La Croix (being mindful of PFAS reports) are reliable choices. Ultimately, making the healthiest choice means being an educated consumer who reads labels, researches testing, and considers personal dietary needs. As with any food or drink, moderation is key, and plain water remains the gold standard for hydration. For those looking to avoid all potential contaminants and additives, creating your own sparkling water is a fantastic alternative.
