The Basics: Decoding Seltzer vs. Sparkling Water
Before determining what is the healthiest seltzer to drink, it's important to understand the distinctions between different types of carbonated water.
- Seltzer: This is simply plain water that has been artificially infused with carbon dioxide (CO2) for carbonation. It typically has no added minerals, calories, or sodium.
- Sparkling Mineral Water: This type of water comes from a natural spring or well and gets its carbonation and distinct mineral content (like calcium and magnesium) from the source. It can be naturally or artificially carbonated.
- Club Soda: Similar to seltzer, club soda is water that has been artificially carbonated. However, it also includes added minerals, such as sodium bicarbonate and potassium sulfate, which can give it a slightly salty taste.
- Tonic Water: This is the least healthy of the carbonated options. It contains quinine for a bitter flavor and often has significant amounts of added sugars or high-fructose corn syrup. It should be avoided when seeking a truly healthy seltzer option.
Key Factors for Choosing the Healthiest Seltzer
When navigating the vast aisle of bubbly beverages, here are the most important nutritional aspects to consider to find the healthiest option:
No Added Sugar or Artificial Sweeteners
This is the most critical rule. Any seltzer with added sugar is essentially a soda and negates the primary health benefit of choosing seltzer in the first place. Likewise, artificial sweeteners like aspartame or sucralose add sweetness without calories but can cause digestive upset in some people. The best choices are those with zero grams of sugar.
Minimal and Natural Ingredients
Opt for seltzers with simple ingredient lists. Plain seltzer is just water and CO2. Flavored options are typically best when they use "natural flavors" or "natural essences" derived from plant sources. Be wary of long lists of additives, colorings, or other unpronounceable ingredients. Some brands like Spindrift use a small amount of real fruit juice for flavor, which adds a minimal amount of natural sugar but is a healthier alternative to artificial flavorings.
Mindful of Acidity and Dental Health
All carbonated water is slightly acidic due to the formation of carbonic acid. While much less erosive than soda, high consumption over time can still pose a risk to tooth enamel. This risk is compounded by the addition of citrus flavors, which often include citric acid. For dental health, consume seltzer in moderation, consider drinking it with meals, or use a straw to minimize tooth contact.
Check Sodium Content
For most healthy individuals, the sodium in club soda or sparkling mineral water is negligible. However, if you have high blood pressure or are on a sodium-restricted diet, it's worth checking the label to ensure it doesn't contribute significantly to your daily intake.
Hydration Benefits and Digestive Considerations
Sparkling water is just as hydrating as still water, making it an excellent way to meet your daily fluid requirements, especially if you find plain water unappealing. For many, the fizz and flavor are satisfying and help reduce reliance on sugary beverages. However, the carbonation can cause bloating, gas, or exacerbate symptoms for those with gastrointestinal issues like IBS or acid reflux. Pay attention to how your body reacts and moderate your intake if necessary.

DIY Seltzer: The Ultimate Control
For the ultimate control over ingredients and quality, consider making your own seltzer at home using a machine like a SodaStream. This allows you to use your own tap water, which in many areas is fluoridated—a key mineral for dental health that bottled waters often lack. You can then add fresh fruit slices (like lemon, lime, or berries) for flavor without adding sugar or artificial ingredients.
Conclusion: Choosing Your Bubbly Best
The healthiest seltzer is the one that best suits your dietary needs while helping you stay hydrated. For most people, this means opting for a plain or naturally flavored seltzer with no added sugar or artificial sweeteners. Brands like Waterloo and LaCroix offer a simple, zero-calorie solution, while sparkling mineral waters like Topo Chico can provide additional minerals. Be mindful of the acidity, especially with citrus flavors, and listen to your body to avoid digestive discomfort. If you find yourself reaching for a bubbly drink more often, remember to alternate with still water, and consider the simple, customizable option of making your own. By understanding the ingredients and potential health effects, you can make a truly refreshing and healthy choice.
