High-calcium mineral water in France: top 10 compared
Among the mineral waters available in France in the h2oMatch database, these have the highest calcium values.
Several mineral waters available in France are notable for being among the most calcium-rich in Europe, reflecting the specific geology of their source regions.
Highest Calcium Mineral Waters in France (selection)
Here are some of the highest calcium mineral waters available in the French market in the h2oMatch database.
| Water | Calcium (mg/L) | Magnesium (mg/L) | Fixed residue (mg/L) |
|---|---|---|---|
| Hépar | 549 | 119 | 2513 |
| Courmayeur | 549 | 58.9 | 2058 |
| Contrex | 479 | 72.2 | 2073 |
| Chateldon | 355 | 49 | 1882 |
| Rozana | 260 | 160 | 2995 |
| Vittel | 240 | 42 | 1084 |
| Saint Amand | 176 | 46 | 859 |
| Quézac | 165 | 69 | 980 |
| La Salvetat | 160 | 7.5 | 520 |
| Badoit | 153 | 80 | 1100 |
Hépar and Courmayeur share the same calcium value of 549 mg/L, yet Hépar contains about twice as much magnesium (119 versus 58.9 mg/L). Rozana, only fifth for calcium, has the highest fixed residue in the table (2995 mg/L), so calcium alone does not describe overall mineralization.

Waters with high calcium levels are often strongly mineralized in general, which gives them a pronounced taste. Beyond just calcium, their full mineral profiles (including magnesium, sodium, and bicarbonates) differ considerably, which is important when considering them for everyday use.
Under EU natural mineral water regulation, the indication ‘contains calcium’ may be used when calcium exceeds 150 mg/L. All ten waters in this ranking exceed that threshold.
The presence of Courmayeur, an Italian water from the Aosta Valley, shows that the French market also includes prominent imported waters.
Hépar is a highly mineralized water, particularly rich in calcium, magnesium, and sulfates. Due to its high sulfate content, it can have a laxative effect, and its pronounced mineral profile may not suit every person or every daily-use context.

FAQ
Which mineral waters have the most calcium in France?
Hépar and Courmayeur share first place with 549 mg/L, ahead of Contrex (479 mg/L). Values come from official labels; the top 10 in the h2oMatch database appears in the table above.
Which water is high in both calcium and magnesium?
Hépar is the standout case: 549 mg/L of calcium and 119 mg/L of magnesium, topping both French rankings. Rozana also combines the two (260 and 160 mg/L). The full magnesium ranking is on the dedicated page.
When can a water be called 'calcic'?
Under EU natural mineral water regulations, the indication ‘contains calcium’ may be used when calcium exceeds 150 mg/L. Notably, every one of the top 10 waters available in France clears that threshold.
Is the calcium in mineral water absorbed by the body?
Yes. Published studies indicate that calcium dissolved in mineral water is well absorbed, so a high-calcium water adds to the calcium from the rest of the diet. For context, the EU nutrient reference value for calcium, used on food labels, is 800 mg per day. A water with 549 mg/L contains 549 mg of calcium per litre.
Are these calcium-rich waters still or sparkling?
The top three - Hépar, Courmayeur and Contrex - are still, as is Vittel. Chateldon, Rozana, Quézac, La Salvetat and Badoit are lightly sparkling. The water type is always shown on the label.
All values are based on official mineral water labels and the h2oMatch database.
