Carbonated drinks are everywhere — from LaCroix at the office fridge to club soda behind the bar. They look the same, taste similar, and both fizz delightfully. But when it comes to health, many people find themselves wondering about the real differences: Club Soda vs Sparkling Water — are they truly the same, and which one is the healthier choice for daily drinking?
The short answer: sparkling water is generally healthier for daily hydration, while club soda has its place in cocktails and cooking. But to really understand why, let’s break it down step by step.
What They Really Are
Club Soda
Club soda is water that has been artificially carbonated and enhanced with added minerals such as sodium bicarbonate, potassium sulfate, or sodium chloride to alter taste.
- Artificially carbonated water (CO₂ added by manufacturers).
- Contains added minerals.
- Taste: slightly salty or mineral-like.
- Mostly used in cocktails, mixers, and baking.
Sparkling Water
Sparkling water is naturally or artificially carbonated water that contains no added minerals, although natural mineral varieties may include calcium, magnesium, and other trace elements.
- Either naturally carbonated (from springs like San Pellegrino) or infused with CO₂ without additives.
- May contain natural minerals, but nothing artificial.
- Taste: clean, crisp, sometimes subtly mineral.
- Best for everyday drinking as a soda alternative.
Key Difference: Club soda = added sodium/minerals. Sparkling water = natural (or plain).
Nutritional Showdown
| Nutrient | Club Soda (per 12 oz) | Sparkling Water (per 12 oz) |
| Calories | 0 | 0 |
| Sugar/Carbs | 0 | 0 |
| Sodium | 20–200 mg | 0–10 mg |
| Minerals | Added (bicarbonates, sulfates) | Natural (calcium, magnesium in mineral waters) |
| pH (Acidity) | ~5–6 | ~5 |
Both are calorie-free and sugar-free.
The real difference = sodium and additives in club soda.
pH Levels Explained: How Acidic Are They Really?
- What pH Means: pH measures acidity/alkalinity. Neutral is 7. Below 7 = acidic, above 7 = alkaline.
- Club Soda: pH ~5–6. Slightly acidic, but buffered by added minerals.
- Sparkling Water: pH ~4.5–5. Slightly more acidic, especially if citrus-flavored.
Comparison to Other Drinks:
- Cola → ~pH 2.5 (very acidic).
- Orange juice → ~pH 3.0.
- Coffee → ~pH 5.0.
- Plain water → ~pH 7.0 (neutral).
Key Takeaway: Both are mildly acidic but far less erosive than soda or juice. With good dental hygiene, risks are minimal.

Flavored Options: Club Soda vs Sparkling Water
Flavors are where things get tricky — and where health risks can sneak in.
| Drink | Flavor Options | Common Additives | Health Considerations |
| Sparkling Water | Widely available in fruity flavors (LaCroix, Bubly, Spindrift) | Natural flavors, citric acid, sometimes real fruit juice | Acidic flavors can erode enamel; most are sugar-free, but watch for artificial sweeteners. |
| Club Soda | Less common; some brands offer lemon-lime or berry versions, often marketed as mixers | Sodium, citric acid, sometimes added sugar | Higher sodium + acidity may increase bloating and affect blood pressure if consumed often. |
Health Risks at a Glance
- Dental Erosion: Flavored versions of both club soda and sparkling water are more erosive on tooth enamel than their plain counterparts, due to citric acid.
- Hidden Sweeteners: Some flavored club sodas contain added sugar, moving them closer to soft drinks than healthy hydration.
- Digestive Effects: Extra acidity can worsen bloating, heartburn, or reflux in sensitive individuals.
- Sodium Watch: Flavored club sodas still carry sodium — not ideal for kids, pregnancy, or people with high blood pressure.
Editorial Takeaway:
- For daily hydration, stick with plain sparkling water or lightly flavored versions without added sugar.
- Use flavored club soda mainly for cocktails — not as an everyday water replacement.
Health Impacts: How They Affect Your Body
Hydration
- Both hydrate equally well as plain water.
- Myth busted: carbonation does not dehydrate you.
Teeth & Bones
- Sparkling water is mildly acidic, but far less harmful than soda.
- Studies show it’s ~100x less erosive than cola.
- Club soda’s sodium doesn’t damage teeth but high sodium diets can affect bone health.
Digestion & Gut
- Sparkling water may ease constipation and indigestion.
- Club soda has long been used for mild indigestion relief.
- Downsides: can cause bloating or gas for sensitive people.
Heart & Kidneys
- Club soda’s sodium can be a concern for hypertension or kidney issues.
- Sparkling mineral water may improve heart health due to natural magnesium/calcium.
Club Soda vs Sparkling Water for Kids & Pregnancy: Safety Considerations
For Kids
- Plain water and milk are best for everyday hydration.
- Sparkling Water: Safe occasionally for older kids, but carbonation may cause gas. Flavored versions may increase enamel erosion risk.
- Club Soda: Added sodium offers no benefit and should be avoided as a daily drink.
Bottom line for kids: Water first. Sparkling water okay occasionally, but skip club soda.
For Pregnancy
- Sparkling Water: Generally safe in moderation. The fizz can ease nausea or morning sickness. Choose unsweetened, additive-free versions.
- Club Soda: Also safe occasionally, but sodium can worsen water retention or high blood pressure.
Bottom line for pregnancy: Sparkling water is the better daily choice. Club soda should be limited.
Everyday Uses: Where Each Works Best
- Club Soda: Cocktails, baking, and occasional digestion aid.
- Sparkling Water: Daily hydration, soda replacement, weight management.
Stat: 1 in 3 Americans now replaces soda with sparkling water weekly (Statista, 2023).

Club Soda vs Sparkling Water How Much Is Too Much?
Sparkling Water
- Dental Health: Plain sparkling water can be enjoyed daily. Limit flavored versions (with citric acid) to 1–2 cans a day to reduce enamel wear.
- Digestive Sensitivity: Most people tolerate it well, but if you’re prone to bloating, reflux, or IBS, keep it to 2–3 servings per day.
- Hydration: Sparkling water hydrates as well as still water, but experts recommend balancing with plain water to protect teeth and digestion.
Safe Range: 1–3 cans (12 oz each) daily is fine for most people.
Club Soda
- Sodium Content: Depending on the brand, a single 12 oz serving may contain 20–200 mg of sodium. Regularly drinking multiple cans can contribute significantly to your daily intake, especially if you already consume salty foods.
- Health Concerns: People with high blood pressure, kidney disease, or heart concerns should be more cautious.
- Everyday Use: Best reserved for cocktails, mixers, or occasional baking rather than daily hydration.
Safe Range: Up to 1 can per day for most healthy adults, but avoid making it your primary water source.
