What is the mineral content of popular still mineral water brands?
Mineral content varies a lot by brand. From the makers' own analyses, Gerolsteiner Ursprung is highest of those we checked (590 mg/L calcium, 167 mg/L magnesium), while Evian has 80 and 26 and Volvic 12 and 8. All figures below are manufacturer data.

Which mineral water has the most minerals?
Of the waters whose makers’ pages we opened, Gerolsteiner Ursprung has the most. Other brands, such as Contrex, may be higher; we could not open Contrex’s page, so it is not compared here.
| Water (mg per liter) | Calcium | Magnesium | Sodium | Bicarbonate |
|---|---|---|---|---|
| Gerolsteiner Ursprung | 590 | 167 | 223 | 3,144 |
| Gerolsteiner Naturell | 125 | 44 | 17 | 577 |
| Evian | 80 | 26 | 6.5 | 360 |
| Volvic | 12 | 8 | 12 | 74 |
What else is in the water?
Evian lists potassium 1, sulfates 15, silica 14, chlorides 10 and nitrates 3.8 mg/L, with dissolved solids of 345 mg/L at 180 C and a pH of 7.2. Volvic lists potassium 6, sulphates 9, silica 32, chlorides 15 and nitrates 7.3 mg/L, dry residue of 130 mg/L and a pH of 7. Gerolsteiner Ursprung lists potassium 26, chloride 63 and sulfate 100 mg/L.
Does mineral water contain potassium and electrolytes?
Yes, in small amounts for these brands: potassium ranges from 1 to 26 mg/L in the tables above, alongside calcium, magnesium and sodium.
Do the numbers change?
Yes. Volvic’s own pages show slightly different values by bottle size and date, and none of these pages are independent lab reports. Check the label on your bottle.
What is on a mineral water ingredients list?
Natural mineral water is not made from a recipe, so its label shows an analysis rather than added ingredients. Under EU Directive 2009/54/EC (Article 7), labels must carry a statement of the analytical composition giving the water’s characteristic constituents, the place where the spring is exploited and the name of the spring, and information on any treatments the water has had. That is why bottles list minerals such as calcium, magnesium, sodium and bicarbonate in mg per liter.
What makes it natural mineral water?
The Directive defines natural mineral water as microbiologically wholesome water that originates in an underground water table or deposit and emerges from a spring. It must be clearly distinguishable from ordinary drinking water by its mineral content, trace elements or other constituents, and by its original purity. The wording on the front must be “natural mineral water” or an official carbonated variant.
The Directive also reserves the term “spring water” for a separate category and bars labels from suggesting characteristics the water does not have. Rules outside the EU differ, so check the label of your bottle.
