Mineral Water with High Magnesium in the USA: Top 5 Compared
Among the mineral waters available in the USA in the h2oMatch database, these have the highest magnesium values.
Magnesium values in mineral water range from a few mg/L to more than 100 mg/L. On the US market, the highest values come from imported European brands.
Mineral waters with the most magnesium in the USA — top 5 by magnesium content.
The ranking covers natural mineral waters available on the US market listed in the h2oMatch database.
| Water | Magnesium (mg/L) | Calcium (mg/L) | Fixed residue (mg/L) |
|---|---|---|---|
| Gerolsteiner | 108 | 348 | 2479 |
| Badoit | 80 | 153 | 1100 |
| San Pellegrino | 49.6 | 174 | 862 |
| San Benedetto | 28.5 | 49.8 | 273 |
| Evian | 26 | 80 | 345 |
Gerolsteiner is the only water above 100 mg/L magnesium and also the most mineralized, with a fixed residue of 2479 mg/L. San Benedetto and Evian, at the bottom of the table, contain less than 30 mg/L.

GEROLSTEINER from Germany leads at 108 mg/L. It is also rich in calcium and bicarbonate, so magnesium is only one part of its mineral profile.
While the US has no domestic mineral water tradition comparable to Europe's, the growing availability of European imports gives American consumers access to the same magnesium-rich options found in Europe.
Only Gerolsteiner and Badoit exceed the 50 mg/L threshold for the EU indication ‘contains magnesium’ on the US market.
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 magnesium in the USA?
Gerolsteiner leads with 108 mg/L, followed by Badoit (80 mg/L) and San Pellegrino (49.6 mg/L). Values come from official labels; the top 5 is in the table above.
When may a water carry the indication 'contains magnesium'?
The European label indication applies above 50 mg/L: on the US market only Gerolsteiner and Badoit exceed it.
How much magnesium can mineral water contribute per day?
A litre of Gerolsteiner contains 108 mg of magnesium. For context, EFSA sets an adequate intake of 300 mg per day for adult women and 350 mg for adult men. Water does not replace a balanced diet, but it can complement it without calories.
What does magnesium-rich water taste like?
Higher magnesium lends water a faintly bitter, mineral edge — part of why strongly mineralized waters taste more assertive. The lower rows of the table offer gentler profiles.
Does sparkling water have more magnesium than still?
Carbonation itself adds no magnesium — the mineral content depends on the spring, not the bubbles. Gerolsteiner and San Pellegrino are naturally high in minerals and happen to be sparkling; the label of each specific product is what counts.
All values are based on official mineral water labels and the h2oMatch database.
