Honestly, the "is sparkling water actually good for you" debate is one of those things that just won't die. You’ve probably heard the rumors. People claim it rots your teeth or leaches calcium from your bones, or maybe it’s just "fake" hydration. But here’s the thing: most of that is just plain wrong. Carbonated water—whether you call it soda water, seltzer, or club soda—is essentially just water with a personality. It’s bubbly. It’s crisp. And if you’re trying to kick a soda habit, it’s basically a literal lifesaver.
We need to talk about what's actually happening in that glass.
When you drink soda water, you’re consuming carbon dioxide gas that has been dissolved under pressure. This creates carbonic acid. That sounds scary, right? Acid. But the pH level of most plain sparkling waters is around 3 to 4, which is mildly acidic but nowhere near the enamel-destroying levels of a standard cola or even some fruit juices.
The Science Behind Soda Water Benefits and Digestion
Let’s get into the gut stuff because this is where things get interesting. Most people assume the bubbles just make you bloated. While that can happen if you chug a liter of San Pellegrino in thirty seconds, the actual physiological effects are often the opposite.
Research published in the Journal of Gastroenterology and Hepatology found that carbonated water can actually help with dyspepsia (indigestion) and constipation. In one specific study, people who drank carbonated water for two weeks saw significant improvements in their gallbladder emptying and overall bowel movements compared to those drinking still tap water. It’s not magic; it’s likely that the carbonation triggers certain receptors in the mouth and throat that signal the digestive system to wake up.
It helps you feel full. Seriously.
If you’re trying to manage your weight, soda water is a secret weapon. The bubbles create a sensation of fullness in the stomach that flat water just can’t replicate. There was a small but fascinating study where young women drank 250ml of sparkling water on an empty stomach and reported feeling significantly more satiated than those who drank still water. This happens because the gas expands the stomach lining slightly, sending "I'm full" signals to your brain faster.

Does it actually hydrate you?
Short answer: Yes.
Long answer: Absolutely yes.
The American Journal of Clinical Nutrition has looked into the "hydration index" of various beverages. They found no meaningful difference in hydration levels between still and sparkling water. If you’re one of those people who finds plain water boring and struggles to hit your daily intake, carbonation is your best friend. If you drink it, you’re hydrated. Period.
Addressing the Bone and Teeth Myths
This is the big one. The "soda water causes osteoporosis" myth. This stems from a misunderstanding of a 2006 study (the Framingham Osteoporosis Study) which found that cola consumption was linked to lower bone mineral density in women. But here’s the kicker: it wasn’t the carbonation. It was the phosphorus. Most dark sodas contain phosphoric acid, which can interfere with calcium absorption.
Plain soda water doesn't have phosphorus.
A study involving postmenopausal women who drank a liter of carbonated water daily for eight weeks showed no loss of bone minerals. In fact, some researchers suggest that the mineral content in certain sparkling waters (like those high in calcium) might actually support bone health.
As for your teeth? It’s a bit more nuanced.

Plain sparkling water is about 100 times less damaging to tooth enamel than sugary soft drinks. According to the American Dental Association (ADA), as long as there aren’t added sugars or citric acids, the erosive potential of carbonated water is very low. However, if you’re drinking "sparkling lemon-lime" water all day, that added citric acid changes the game. Stick to the plain stuff or add your own fresh fruit to keep the pH levels in a safe zone.
Swallowing and Satiety: The Hidden Perks
Did you know soda water can improve your ability to swallow?
It sounds weird, but "cold carbonated water" has been shown to stimulate the nerves responsible for the swallowing reflex more effectively than any other liquid. This is often used in clinical settings for people with dysphagia (difficulty swallowing).
Then there’s the psychological aspect.
The "bite" of carbonation mimics the sensation of drinking a beer or a soda. For someone trying to cut back on alcohol or high-fructose corn syrup, that sensory experience is a powerful tool for behavior change. You get the fizz, the throat hit, and the cold refreshing sensation without the 150 calories or the hangover.
Why the Source Matters
Not all bubbles are created equal. You’ve got:

- Seltzer: Just water and CO2.
- Club Soda: Carbonated water with added minerals like sodium bicarbonate or potassium sulfate to mimic the taste of natural mineral water.
- Sparkling Mineral Water: Bottled at a natural source (like Perrier or Gerolsteiner), containing naturally occurring minerals like magnesium and calcium.
If you’re watching your sodium intake, club soda might have a tiny bit more than you want, though it’s usually negligible (around 75mg per can). Mineral water is often the "gold standard" because you’re actually getting micronutrients while you hydrate.
What Most People Get Wrong About Bloating
You might think soda water makes you gassy. Sometimes it does. But it’s usually temporary. When you swallow those bubbles, the gas has to go somewhere. You either burp it up or it moves through the digestive tract.
For people with Irritable Bowel Syndrome (IBS), the carbonation can be a trigger for discomfort. If your gut is sensitive to distension, the gas can cause some cramping. If that’s you, maybe stick to flat water. But for the general population? It’s just air. It’s harmless.
Actionable Steps for the "Fizzy Water" Lifestyle
Don't just start chugging six cans a day without a plan. Use the bubbles strategically.
- Drink it 20 minutes before a meal. If you struggle with overeating, that pre-meal seltzer can take the edge off your hunger.
- Watch the "Natural Flavors." Many canned seltzers use essences that can be acidic. If you’re worried about teeth, drink it with a straw or alongside food to neutralize the pH.
- Use it as a mixer. Swap out the tonic water (which is loaded with sugar) for soda water in your cocktails.
- Check the labels. If you see "Acesulfame Potassium" or "Sucralose" in your sparkling water, you’re not drinking soda water; you’re drinking a diet soda. The health benefits we're talking about apply to the unsweetened stuff.
If you’ve been feeling guilty about your LaCroix habit, stop. You’re hydrating your body, helping your digestion, and probably saving yourself from much worse beverage choices. Just keep an eye on your teeth if you’re a 24/7 sipper, and maybe opt for a high-mineral version once in a while to get those extra electrolytes.
