High-magnesium mineral water in France: top 10 compared
Among the mineral waters available in France in the h2oMatch database, these have the highest magnesium values.
Magnesium is only one part of a water's profile. Among France's high-magnesium waters, other minerals like calcium, sodium, and bicarbonate vary widely, shaping both their taste and overall character.

The volcanic geology of the Massif Central gives France some of the most magnesium-rich mineral waters in Europe.
The top-ranking waters are strongly mineralized overall. For instance, Rozana is also high in sodium and bicarbonate, giving it a very different profile from other magnesium-rich waters.
Hépar is a highly mineralized water, particularly rich in calcium, magnesium and sulfates. Because of 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 contain the most magnesium in France?
Rozana leads with 160 mg/L, ahead of Hépar (119 mg/L) and Badoit (80 mg/L). Values come from official labels; the top 10 in the h2oMatch database appears in the table above.
When may a water carry the indication 'contains magnesium'?
Under EU regulations, the indication ‘contains magnesium’ may be used when magnesium exceeds 50 mg/L. In this ranking, the top six waters meet that threshold.
Are magnesium-rich waters also high in sodium?
Not necessarily: Courmayeur pairs high magnesium (58.9 mg/L) with very low sodium (0.7 mg/L). At the other end, Rozana contains 540 mg/L of sodium and Badoit 180 mg/L. Both values appear on every label.
What does a magnesium-rich water taste like?
At high concentrations, magnesium gives water a slightly bitter note: it is one of the reasons highly mineralised waters have a more pronounced character than light waters.
How much magnesium can mineral water provide relative to daily needs?
One litre of Rozana contains 160 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.
All values are based on official mineral water labels and the h2oMatch database.
