Mineral Water with High Calcium in the USA: Top 5 Compared
Among the mineral waters available in the USA in the h2oMatch database, these have the highest calcium values.
Calcium values in mineral water range from a few mg/L to more than 500 mg/L. On the US market, the highest values come from imported European waters whose springs rise through limestone and other carbonate rock.
Mineral waters with the most calcium in the USA — top 5 by calcium content.
The ranking covers natural mineral waters available on the US market listed in the h2oMatch database.
| Water | Calcium (mg/L) | Magnesium (mg/L) | Fixed residue (mg/L) |
|---|---|---|---|
| Gerolsteiner | 348 | 108 | 2479 |
| San Pellegrino | 174 | 49.6 | 862 |
| Badoit | 153 | 80 | 1100 |
| Perrier | 150 | 3.9 | 456 |
| Topo Chico | 120 | 11 | 630 |
Gerolsteiner has twice the calcium of San Pellegrino (348 versus 174 mg/L) and a much higher overall mineralization, with a fixed residue of 2479 mg/L. The other four waters sit in a narrower band between 120 and 174 mg/L.

A higher calcium value alone does not make a water better: magnesium, sodium, bicarbonate and overall mineralization also shape its taste and how it fits everyday drinking.
The US market offers several imported European mineral waters with high calcium content, led by GEROLSTEINER (348 mg/L).
Under the EU label criteria we reference throughout h2oMatch, a water may carry the indication ‘contains calcium’ above 150 mg/L: the first three waters in this top 5 qualify.
A note on definitions: h2oMatch lists natural mineral waters in the European legal sense — officially recognised waters with a stable mineral composition. The US FDA defines "mineral water" differently, requiring at least 250 ppm of total dissolved solids; European natural mineral waters have no minimum, which is why very light waters like Sant'Anna appear here. Threshold figures cited on this page are EU label criteria, not US regulations.

FAQ
Which mineral water has the most calcium in the USA?
Gerolsteiner leads with 348 mg/L, ahead of San Pellegrino (174 mg/L) and Badoit (153 mg/L). Values come from official labels in the h2oMatch database; the top 5 is in the table above.
Which water combines high calcium and high magnesium in the US market?
Gerolsteiner is the standout: 348 mg/L of calcium and 108 mg/L of magnesium, leading both US rankings. Badoit (153 and 80 mg/L) is the runner-up combination.
When may a water carry the indication 'contains calcium'?
Under the European label criteria used across h2oMatch, the indication applies above 150 mg/L of calcium. The first three waters in the US top 5 qualify.
How much calcium can a litre of mineral water provide?
A litre of Gerolsteiner contains 348 mg of calcium. For context, the EU nutrient reference value for calcium, used on food labels, is 800 mg per day. Calcium from water adds to calcium from the rest of the diet rather than replacing it.
Why are the highest-calcium waters in America all European?
Calcium-dense mineral water needs geology that dissolves limestone or volcanic rock into the spring — common in Germany, Italy and France, rare among recognised American sources. The US top 5's only non-European entry, Topo Chico (120 mg/L), comes from Mexico.
All values are based on official mineral water labels and the h2oMatch database.
