The Criteria for Healthy Sparkling Water
Choosing a healthy sparkling water goes beyond simply finding a zero-calorie, zero-sugar option. Several factors influence the overall healthfulness of a bubbly beverage.
Ingredient Purity
At its core, sparkling water should be just that: water and carbon dioxide. The healthiest brands contain minimal to no added ingredients beyond pure water and bubbles. Flavored varieties can introduce complexities. For instance, some use fruit essences or essential oils for flavor, while others use real fruit juice. The presence of natural or artificial flavors can be a point of consideration for health-conscious consumers. Artificial sweeteners, citric acid, and preservatives are also common additives to check for on the nutrition label.
PFAS Contamination
Recent reports have raised concerns about the presence of Per- and Polyfluoroalkyl Substances (PFAS), also known as “forever chemicals,” in some popular sparkling water brands. These substances have been linked to potential health issues, making their absence a critical factor for a healthy choice. Some brands, like Mountain Valley, have been shown to have non-detectable levels, while others, including Bubly, LaCroix, and Topo Chico, have faced scrutiny over higher levels.
Mineral Content and Source
The source of the water significantly impacts its mineral profile. Sparkling mineral water comes from a natural spring or well and contains naturally occurring minerals like calcium, magnesium, and sodium, which can offer health benefits like aiding blood pressure regulation. Seltzer, on the other hand, is simply water artificially carbonated without added minerals, making it a purer, sodium-free base.
Dental Health Considerations
Plain sparkling water is generally safe for dental health, but the carbonation process does create a weak carbonic acid. Flavored waters, especially those with added citric acid, can increase the risk of enamel erosion over time. Enjoying these drinks with meals and using a straw can help mitigate any potential risk.

| Mountain Valley | Natural Carbonation | Non-detectable levels reported | High (Natural Mineral Water) | Premium mineral water, purity |
| Gerolsteiner | Natural Mineral Water | Non-detectable levels reported | High (Natural Mineral Water) | Mineral-rich, robust flavor |
| Waterloo | Natural Flavors (Essences) | Reported low levels | Low (Seltzer) | Bold flavor, zero calories, zero sugar |
| LaCroix | Natural Flavors (Essences) | Detected PFAS levels | Low (Seltzer) | Wide availability, mild flavors |
| Topo Chico | Mineral Water | High detected PFAS levels | Moderate (Natural Mineral Water) | Strong carbonation, classic mixer |
Top Recommendations for the Healthiest Brands
Based on the health criteria, several brands stand out for their purity and ingredient quality.
- Spindrift: Flavored with real fruit juice instead of vague 'natural flavors,' Spindrift is one of the cleanest flavored options available. The real juice gives it a transparent, minimally processed quality, though it does contain a small amount of natural sugar from the fruit.
- Mountain Valley Sparkling Water: For those who prefer a classic, naturally sourced mineral water, Mountain Valley offers a pristine option. It is sourced from protected underground springs and has consistently tested free of PFAS chemicals. The natural minerals can also provide some health benefits.
- Gerolsteiner Sparkling Natural Mineral Water: Sourced from Germany, Gerolsteiner is another excellent choice for mineral-rich sparkling water. Known for its clean taste and naturally high mineral content, it has also been reported with non-detectable levels of PFAS.
- Waterloo Sparkling Water: If you want a bold, unsweetened flavor without real fruit juice, Waterloo is a top contender. It uses naturally extracted fruit essences and reports low levels of PFAS, making it a reliable, zero-calorie seltzer.
- Liquid Death Sparkling Water: A newer entrant to the market, Liquid Death is sourced from the Austrian Alps and sold in infinitely recyclable aluminum cans. It has been reported to have non-detectable levels of PFAS and is a straightforward, clean sparkling water.
Factors to Consider When Choosing
When selecting a sparkling water, your personal health goals and preferences should guide your choice. Here is a quick checklist.
- Read the label carefully: Look for minimal ingredients. Plain sparkling water is typically just carbonated water. Flavored options should be checked for sugar, artificial sweeteners, and preservatives.
- Know your water type: Remember the differences between seltzer (plain, no added minerals), club soda (added minerals, often sodium), and sparkling mineral water (naturally occurring minerals).
- Assess flavor sources: If you prefer flavored, decide if real fruit juice (like Spindrift) or natural essences (like Waterloo) aligns better with your preferences. Be mindful of added citric acid in some flavored options, which can increase acidity.
- Consider sourcing and contaminants: For absolute purity, consider brands like Mountain Valley or Liquid Death that have tested clean for PFAS. For more information on sourcing and testing, check resources like this article from the Houston Methodist hospital blog.
- Evaluate packaging: Many brands offer their water in recyclable glass or aluminum cans. Considering eco-friendly packaging can be a bonus for some consumers.
Conclusion: The Final Verdict
While there is no single "healthiest" brand for everyone, the best option depends on your specific priorities. For those seeking the purest, most minimally processed water, unflavored options like Mountain Valley or Liquid Death, which have tested non-detect for PFAS, are excellent choices. If flavor is a priority, Spindrift, which uses real fruit, offers a transparent and high-quality option, while Waterloo provides a zero-calorie, zero-sugar flavored alternative. Always check the ingredient list to ensure you are selecting a product with minimal additives. Ultimately, the healthiest brand is the one that best fits your needs while being free from unwanted contaminants, encouraging you to stay hydrated without the downsides of sugary sodas.
How to Choose the Healthiest Sparkling Water
- Check the Ingredient List: Opt for plain sparkling water with minimal ingredients to avoid artificial sweeteners, excess sodium, or citric acid.
- Seek Real Flavor: Choose brands like Spindrift that use real fruit for flavor over those with ambiguous “natural flavors” or artificial essences.
- Beware of PFAS: Research brands for PFAS contamination, as some popular waters have tested positive for these 'forever chemicals'.
- Consider Mineral Content: If you need electrolytes, look for naturally sourced mineral waters like Mountain Valley or Gerolsteiner.
- Use a Straw for Dental Health: To protect tooth enamel from the weak carbonic acid, drink flavored sparkling waters with a straw, especially if consumed frequently.
Final Recommendations
- Best for Purity: Mountain Valley or Liquid Death, both with non-detectable PFAS levels.
- Best for Flavor with Real Fruit: Spindrift, made with real squeezed fruit juice.
- Best for Zero-Sugar Flavor: Waterloo, using natural fruit essences without sweeteners.
- Best for Minerals: Gerolsteiner, a natural mineral water with a robust mineral profile.
Ultimately, a plain, unsweetened sparkling water with a clean source is your safest bet for maximum health benefits.
