For many, the refreshing tingle of carbonation is a welcome alternative to plain water, but the health benefits can vary significantly depending on the type and brand. While many people use the terms 'sparkling water,' 'seltzer,' and 'mineral water' interchangeably, they are distinctly different in their origin and content.
Deciphering the different types of bubbly water
To determine the healthiest option, you must first understand the fundamental differences between the various types of carbonated water available.
Sparkling Mineral Water
This type is sourced from natural springs and contains a variety of minerals like calcium, magnesium, and potassium, which are absorbed as the water flows through underground rock. The carbonation can be naturally occurring from geological gases or may be added later. Brands like San Pellegrino and Perrier fall into this category. The mineral content can give the water a unique, subtle taste and provides essential electrolytes, especially beneficial for rehydration after exercise.
Seltzer Water
Seltzer is simply plain water that has been artificially infused with carbon dioxide to create bubbles. Unlike mineral water, it does not naturally contain minerals, giving it a neutral taste. This makes it a popular base for creating your own flavored drinks. Many flavored seltzer brands also add natural fruit essences to their products, offering a zero-calorie, zero-sugar option for flavor enthusiasts. Popular brands include LaCroix and Bubly.
Club Soda
Similar to seltzer, club soda is also artificially carbonated water. The key difference is the addition of mineral salts, such as sodium bicarbonate and potassium sulfate, to enhance the flavor and provide a slightly saltier taste. Because of its distinct flavor profile, it is a common mixer for cocktails and is generally not recommended as a primary source of daily hydration due to its higher sodium content.
How to spot the healthiest options
When evaluating the healthiness of a bubbly water, checking the ingredients list is crucial. The healthiest choices will be plain, unsweetened, and free of additives. If you prefer flavor, look for options that use natural fruit essences over added sugars or artificial sweeteners.
Best practices for selection:
- Read the label: Always check the nutrition facts. Look for 0 calories, 0 sugar, and minimal sodium.
- Prioritize plain: Plain sparkling mineral water or unflavored seltzer is the purest and healthiest choice.
- Choose natural flavors: If you want flavor, opt for brands that use natural fruit essences, not artificial flavors or sweeteners.
- Replenish with minerals: If you are an athlete or sweat heavily, a natural sparkling mineral water can help replenish lost electrolytes.
- Consider potential side effects: If you experience bloating or gas, you may want to moderate your intake. Plain still water remains the ultimate benchmark for hydration.
Potential drawbacks to be aware of
While unsweetened bubbly water is a vast improvement over sugary soda, it is not without its considerations. The carbonation creates carbonic acid, which can be mildly acidic and may affect tooth enamel over time, especially with frequent, all-day sipping. Flavored varieties, particularly those with added citric acid like lemon or lime, can be more acidic and pose a greater risk to dental health. To mitigate this risk, dentists recommend using a straw, drinking with meals, or rinsing your mouth with still water after consumption.

Conclusion: Making the right choice
Ultimately, the healthiest bubbly water is the one that is free of added sugars, artificial sweeteners, and excessive additives. Plain sparkling mineral water provides naturally occurring electrolytes, while plain seltzer is a neutral, hydrating base. For flavored options, stick to brands using natural fruit essences or a splash of real fruit juice. By reading labels and understanding the different types, you can make an informed choice that supports your hydration and overall health without compromising on taste. Remember that moderation is key, especially when it comes to dental health, and still water remains the gold standard.

How to make your own flavored bubbly water
To have complete control over ingredients, consider making your own flavored sparkling water at home.
- Start with plain seltzer: Buy unflavored seltzer water or use a home carbonation machine.
- Add fresh fruit: Muddle fresh fruits like berries, cucumber, or citrus slices directly into the water for a subtle infusion. You can also make a fruit syrup for a more concentrated flavor.
- Include herbs: Herbs such as mint, basil, or rosemary can add a refreshing, unique twist.
- Use zest: A small amount of citrus zest can provide a potent, natural aroma and flavor without the added acidity of juice.
