What Exactly Is Seltzer Water?
Seltzer water is simply plain water that has been artificially carbonated by infusing it with carbon dioxide gas under pressure. It is distinct from other bubbly drinks in that it contains no added minerals or sodium. This sets it apart from sparkling mineral water, which is naturally carbonated and contains minerals from its underground source, and club soda, which has added minerals for a slightly salty taste. Understanding these distinctions is crucial, as the health implications can vary based on the beverage's composition.
The Health Benefits of Seltzer
For many, seltzer water is a flavorful and satisfying alternative to plain water. This can be especially helpful for individuals who struggle to meet their daily hydration goals with still water alone. Since unsweetened seltzer is calorie-free, it is a much healthier choice than sugary sodas or fruit juices.
Seltzer and Hydration
Studies confirm that plain seltzer water is just as hydrating as regular tap water. Its primary component is water, so it effectively contributes to your daily fluid intake. Staying adequately hydrated is essential for numerous bodily functions, including cognitive performance, digestion, and energy levels. If the fizz encourages you to drink more throughout the day, seltzer can be a valuable tool for maintaining optimal hydration.
Aiding Weight Management
Several studies suggest that carbonated water can enhance feelings of fullness, or satiety. The bubbles from the carbon dioxide can cause a temporary feeling of stomach fullness, which may lead to reduced overall calorie intake. By replacing high-calorie, sugary beverages with zero-calorie seltzer, individuals can significantly reduce their sugar consumption, supporting weight management goals.
Digestion and Stomach Health
For some individuals, seltzer can aid digestion. The carbonation may help move stomach and colonic contents along more quickly, and some research suggests it can improve swallowing ability in those with dysphagia. However, the effects vary, and for people prone to certain conditions, the opposite can be true.
Potential Risks and Drawbacks of Daily Seltzer
While generally safe, a daily seltzer habit isn't without potential downsides. It is important to be aware of these issues to determine if the drink is right for you, especially in large quantities.
Dental Health and Enamel Erosion
The carbonation process makes seltzer water slightly acidic due to the formation of carbonic acid. A study from the Journal of Clinical and Experimental Dentistry suggests that highly carbonated water can be more detrimental to tooth enamel than less carbonated varieties. The risk is elevated with flavored seltzers, which often contain additional acidic ingredients like citric acid. To minimize dental erosion, experts recommend consuming seltzer with meals, drinking through a straw, and rinsing your mouth with plain water afterward to neutralize the acid.
Digestive Discomfort
For some, the gas from carbonation can cause issues like bloating, belching, and gas. Individuals with conditions such as irritable bowel syndrome (IBS) or gastroesophageal reflux disease (GERD) may find that carbonated drinks exacerbate their symptoms. A large intake in a short period can cause gastric distress and weaken the valve that keeps stomach contents down, leading to acid reflux and heartburn.
Bladder Irritation
For those with sensitive or overactive bladders, seltzer water can act as a bladder irritant, potentially increasing the frequency of urination. This is not a concern for most people but is worth noting if you experience such issues.
Seltzer vs. Other Carbonated Beverages: A Comparison
| Feature | Seltzer Water | Sparkling Mineral Water | Club Soda | Tonic Water |
|---|---|---|---|---|
| Sourcing | Artificially carbonated plain water | Naturally carbonated from springs | Artificially carbonated plain water | Artificially carbonated plain water |
| Added Minerals | None | Yes, naturally occurring | Yes (e.g., sodium bicarbonate, potassium sulfate) | Yes (often contains quinine and high fructose corn syrup) |
| Sodium | None | Varies (check label) | Yes, added for flavor | Varies (check label) |
| Calories/Sugar | Zero, if unflavored | Zero, if unflavored | Zero, if unflavored | High in calories and sugar |
| Dental Impact | Low risk, but acidic | Low risk, but acidic | Low risk, but acidic | High risk due to sugar and acidity |
| Best for | Everyday hydration, mixers | Mineral content, specific taste | Mixers, cocktail base | Cocktails, medicinal use |
How to Safely Incorporate Seltzer into Your Daily Routine
For most people, enjoying seltzer daily is a low-risk way to stay hydrated, provided you follow a few guidelines:
- Read the Label: Always choose unsweetened and unflavored varieties to avoid added sugars, artificial sweeteners, and calories that can be detrimental to your health.
- Maintain Variety: Use seltzer to supplement, not replace, your intake of plain water. This ensures you still receive fluoride from tap water, which is important for dental health.
- Time It Right: Drink seltzer with meals to reduce its impact on your teeth, as the increased saliva production during eating helps neutralize acid.
- Use a Straw: For maximum dental protection, drinking seltzer through a straw can minimize direct contact with tooth enamel.
- Listen to Your Body: If you experience bloating, gas, or acid reflux, consider cutting back your intake.

Conclusion: Finding the Right Balance
So, is seltzer ok to drink every day? The answer is a qualified 'yes' for most healthy individuals. As a calorie-free, sugar-free alternative to soda, it can be an excellent tool for staying hydrated and managing weight. However, moderation is key. Being mindful of potential risks, such as dental erosion and digestive discomfort, is important for sustained health. By choosing plain, unsweetened seltzers and consuming them strategically, you can enjoy the satisfying fizz while keeping your health on track. Balancing your intake with plenty of regular water remains the gold standard for overall hydration and wellness.
