Types of Mineral Water: Which Is Best and How to Choose Correctly
When it comes to hydration, not all water is created equal. The label on a bottle of mineral water conceals a true lesson in chemistry and health. What is dry residue? What’s the difference between natural mineral water and alkaline water? And most importantly — what is the best mineral water?
In this complete guide, you’ll discover everything you need to know about types of mineral water, how to read labels, which water suits you best, and a comparison table of the most popular brands.
What is natural mineral water?
Natural mineral water is water sourced from a protected underground spring, rich in mineral salts and natural or added carbon dioxide (CO₂). It is bottled directly at the source and undergoes no chemical treatments, preserving its beneficial properties.
Unlike tap water (chemically treated) or simple spring water, natural mineral water has a stable and certified chemical composition.
Types of mineral water
1. Still water
Free of carbon dioxide, ideal for daily consumption. Suitable for children, pregnant women, and people with digestive issues. The easiest for the body to tolerate.
2. Natural carbonated water
CO₂ comes directly from the source and is not added. It has a distinctive, slightly tangy taste. It stimulates digestion but is not recommended for people with acid reflux.
3. Carbonated water (with added CO₂)
Industrial CO₂ is added after bottling. The taste is similar to naturally carbonated water, but the mineral composition may differ.
4. Semi-carbonated water
An intermediate option with a reduced amount of CO₂. Lightly effervescent, well tolerated by those who cannot handle still water but struggle with carbonated water either.
5. Medicinal mineral water
High concentrations of specific mineral salts — used therapeutically under medical supervision. Examples: sulfurous waters (liver), ferruginous (anemia), iodated, sodium-rich. Not intended for unrestricted daily consumption.
6. Oligomineral water
Very low dry residue (below 50-100 mg/l). Extremely light, suitable for infants and frequent consumption. Examples: Aqua Carpatica, Dorna Izvorul Alb, Hera.
What is alkaline water and is it worth drinking?
Alkaline water has a pH greater than 7 (usually 8-9.5). There are two types:
- Natural alkaline water — high pH due to dissolved minerals (calcium and magnesium carbonates). Examples: Aqua Carpatica (pH 7.94), Zizin (pH 7.2), Bucovina (pH 7.6).
- Ionized alkaline water — processed through electrolysis that artificially increases pH.
What does science say? Current studies do not confirm major benefits of alkaline water over regular mineral water for healthy people. However, natural alkaline water is a good choice — it contains more beneficial minerals and has a pleasant taste.
Conclusion: If you want alkaline water, choose one that is naturally alkaline (check the pH on the label), not one processed industrially.
What is dry residue and how do you interpret it?
Dry residue represents the amount of mineral substances remaining after one liter of water evaporates at 180°C.
| Dry residue | Water type | Suitable for |
|---|---|---|
| Below 50 mg/l | Oligomineral | Infants, sensitive kidneys, frequent consumption |
| 50–500 mg/l | Low mineralized | Daily consumption by healthy adults |
| 500–1500 mg/l | Medium mineralized | Athletes, active people |
| Over 1500 mg/l | Highly mineralized | Occasional or on medical recommendation |
How to read a mineral water label
On any bottle you will find:
- Dry residue at 180°C — total mineralization
- pH — below 7 = acidic, 7 = neutral, over 7 = alkaline
- Calcium (Ca²⁺) — important for bones; minimum 150 mg/l is good
- Magnesium (Mg²⁺) — nervous system, muscles; recommended minimum 50 mg/l
- Sodium (Na⁺) — important for athletes; avoided by those with hypertension
- Nitrates (NO₃⁻) — below 10 mg/l for water intended for infants
- Fluorides — good for teeth in small amounts; avoided in excess

FAQ – Mineral Water (Popular Questions People Also Ask)
What is the healthiest mineral water to drink?
The healthiest mineral water depends on your needs. For daily use, low-mineral water is ideal, while waters rich in magnesium and calcium (like Gerolsteiner) are better for mineral supplementation.
Is it okay to drink mineral water every day?
Yes, it is generally safe to drink mineral water daily, especially if it has low to moderate mineral content. Highly mineralized water should be consumed occasionally rather than every day.
Which is better: mineral water or spring water?
Mineral water contains a consistent level of natural minerals, while spring water typically has fewer minerals. Mineral water is better for added nutrients, while spring water is often preferred for light, everyday hydration.
Does mineral water have side effects?
Mineral water is safe for most people, but consuming high-mineral water in excess may lead to digestive discomfort or excessive intake of certain minerals like sodium.
Is sparkling mineral water bad for your teeth?
Sparkling mineral water is slightly acidic due to carbonation, but it is much less harmful than sugary drinks. When consumed in moderation, it does not significantly damage tooth enamel.
Can mineral water help with digestion?
Yes, sparkling mineral water in particular may help stimulate digestion and reduce bloating for some people.
Which mineral water is best for kidneys?
Low-mineral water is generally best for kidney health, as it does not overload the body with minerals that must be filtered.
Is mineral water better than tap water?
Mineral water provides natural minerals and a consistent composition, while tap water quality varies by location. Both can be safe, but mineral water offers added nutritional benefits.
What does high mineral content mean?
High mineral content means the water contains a larger amount of dissolved minerals like calcium, magnesium, and sodium. This is usually indicated by a higher “residue at 180°C” value on the label.
Can you drink sparkling water instead of soda?
Yes, sparkling mineral water is a much healthier alternative to soda because it contains no sugar, no artificial additives, and fewer calories.
Is mineral water good for skin?
Mineral water can support skin health indirectly by improving hydration and providing minerals like silica and magnesium.
What is the difference between mineral water and purified water?
Mineral water comes from natural sources and contains minerals, while purified water is treated to remove impurities and often lacks natural minerals unless they are added later.
Conclusion
Mineral water is not “just water” — it is an ally for your health, if you know what to choose. Check the label, pick a water that suits your lifestyle, and consume it in moderation. Smart hydration = better health!
