Quick Answer: Yes, sparkling water is a healthy drink choice, as long as it is plain. It hydrates you just like still water, has no sugar or calories, and may even settle your stomach. Trouble starts when brands add sweeteners or flavouring ingredients. The bubbles are harmless.
- Sparkling water is simply water infused with carbon dioxide.
- Hydrates exactly like still water.
- Plain versions have no sugar or calories.
- Helps with swallowing, fullness, and constipation.
- Flavoured ones wear down enamel and hide sugar.
- No credible evidence links plain fizzy water to weaker bones.
What is Sparkling Water?
It is water charged with carbon dioxide gas. The gas forms carbonic acid, which gives that sharp prickle on the tongue. Healthline points out that this acid hits the same nerve receptors in your mouth as mustard, which explains why it feels half irritating and half pleasant.
These drinks are sold as club soda, soda water, seltzer, or fizzy water. Same idea, and apart from seltzer, most have salt added for taste. Natural mineral waters like Perrier and San Pellegrino come from a spring and carry minerals and sulphur compounds.
The Different Types
| Type | What it is | Watch out for |
| Seltzer | Still water with pressurised CO₂ | Added flavouring or sugar |
| Club soda | CO₂ plus sodium bicarbonate and potassium sulphate | Salty, sodium |
| Mineral water | Naturally carbonated, underground, magnesium and calcium | Sodium varies |
| Tonic water | CO₂, quinine, sugar or corn syrup | Real sugar. Limit it |
The FDA separates seltzer and sparkling water by carbonation method and says mineral water must come from underground with set amounts of natural minerals.
WebMD is blunt about tonic. Too much quinine brings stomach upset, headaches, ringing ears, and, in bad cases, organ damage, severe bleeding, or heart rhythm changes. It is a mixer, not a health drink.

Does It Hydrate You Properly?
Yes, settled. Carbon dioxide does not change how your body absorbs water. One study compared thirteen drinks based on urine output and body mass. Sparkling matched still.
Dehydration brings dry mouth, fatigue, headaches, and fuzzy thinking. Long-term, it strains digestion, the heart and kidneys. Harvard Health Publishing says adults need six to eight glasses of fluid daily. The NHS agrees. Fizzy water counts.
Is It Too Acidic?
It has a pH of 5 to 6, so it is mildly acidic. Drinking something acidic does not make you acidic. Your kidneys and lungs shift the extra carbon dioxide and keep blood at 7.35 to 7.45.
The Benefits Worth Knowing
Swallowing gets easier. A 2017 study showed that after drinking carbonated beverages, swallowing improved, particularly in older adults who had been hospitalised.
You feel fuller. Bubbles stretch the stomach, and food may sit longer. The Journal of Nutritional Science and Vitaminology found young women felt fuller in the short term. Lauren Sullivan, a dietitian at Cleveland Clinic, keeps it measured: “Drinking sparkling water may lead to experiencing a short-term, immediate increase in satiety, or fullness.”
Your gut may thank you. The fizz stimulates stomach receptors and gets the intestines moving. Stroke patients with constipation reported relief after two weeks, and people with indigestion did too. It also shifts trapped gas.
It helps you cut back on sugary drinks. Sugary drinks are the leading sources of added sugar for people in the US, and sugar is tied to heart disease, diabetes, and obesity. Billi notes that people drink more water when sparkling water is readily available.

Risks and Side Effects
Teeth: Plain is fine, and the American Dental Association agrees. Work in the American Journal of Clinical Nutrition found colas hurt enamel, while other carbonated drinks did not. A 2001 study found that flavourless sparkling water was 100 times less corrosive than soda, with minerals cancelling out the carbonic acid. Citrus is the problem. A 2007 study concluded that flavoured seltzer water should be considered potentially erosive on the same level as orange juice. Bottled fizz also skips the fluoride in UK tap water.
Gas and bloating: It can cause burping, gas, a full belly, and a mild stomach ache. Brief and harmless. Cut back if it nags.
Reflux: Bad GERD and heavy carbonation do not always mix, though the evidence is thin. Anyone with IBS should ask their GP.
Hidden extras: Artificial sweeteners upset some stomachs, and there is no safe natural chemical stimulant level for children.
Hunger: A New York Post piece flagged research suggesting fizz can leave the stomach empty and trigger hunger hormones.
Common Myths, Sorted
| Claim | Verdict |
| Weakens bones | False. Cola’s phosphoric acid is the culprit |
| Rots teeth like cola | False for plain versions |
| Causes lasting bloating | Exaggerated. Discomfort passes |
| Causes cellulite | False. Zero evidence |
The National Osteoporosis Foundation goes further, suggesting carbonated mineral waters may actually help bone health.
Heart Health and Blood Sugar
A 2023 study found more blood flow in the middle cerebral artery, which sits in the brain, not the heart. A 2015 study found mineral water containing bicarbonate lowered serum glycoalbumin, a blood sugar marker. BMJ Nutrition, Prevention and Health published work in 2025 that hints at a glucose link. All small, all early.
A Word on Flavoured Versions
Mark Schatzker argues in a Food Babe interview that even natural flavouring tricks your body into expecting nutrition that isn’t there. Flavoured seltzers also contain citric acid, which adds taste.
How to Drink It Sensibly
Go unflavoured. Drink it with a meal, or rinse with tap water after. A straw cuts contact with teeth. Mix in still water too, because seltzer carries no minerals. For flavour, add cucumber, peach, berries, pineapple, mint or muddled rosemary.
Making it at home, which the Indigo Soda team recommends, lets you control the water, keep the fluoride, and skip additives. Good filters remove chlorine, heavy metals, and cysts like cryptosporidium and giardia.

Final Verdict
So, is sparkling water a healthy drink choice? Plain, unsweetened fizz is a solid yes. It hydrates you exactly like still water, carries no sugar or calories and may ease constipation, indigestion and swallowing.
The mild acidity will not touch your bones, and plain versions barely mark your enamel. Watch the flavoured cans, the citric acid and the tonic instead. Check the label, keep it simple, and drink it freely. The bubbles were never the problem. Sugar was.
Frequently Asked Questions
Is it bad to drink sparkling water every day?
Ans: Not at all. Plain fizzy water is safe to drink daily and hydrates like still water. If you bloat easily, drink less.
Does sparkling water damage tooth enamel?
Ans: Plain versions barely touch it. Flavoured ones with citric acid are harsher, so drink them with food and rinse your mouth afterwards.
Is sparkling water as hydrating as still water?
Ans: Yes. Carbon dioxide makes no difference to absorption. If bubbles get you drinking more, that is a proper win.
Can sparkling water help you lose weight?
Ans: It has no calories and keeps you full briefly. No fat burner, but swapping it for cola helps.
Is sparkling water bad for your bones?
Ans: No. No study links plain carbonated water to bone loss. The worry came from colas, which contain phosphoric acid.
Which sparkling water is the healthiest?
Ans: Unflavoured seltzer or natural mineral water. Check the label for added sugar, sweeteners, citric acid, and sodium.
