Waters like BORSEC and AQUA MAGNESIA contain notable levels of magnesium, and many Romanian high-mineral waters have been used historically for balneological purposes - a tradition that continues in Romanian spa culture today.
For everyday hydration, high-magnesium mineral waters available in Romania offer a distinctive mineral profile that is often more varied than what is available in Western European markets.
Under EU regulation, the indication ‘contains magnesium’ may be used when magnesium exceeds 50 mg/L: the top six waters in the top 10 exceed that threshold.
The Carpatina case shows how much the spring matters: the Light variant contains 97.6 mg/L of magnesium, while Carpatina Plata has just 5.2 mg/L — same brand, different springs.

FAQ
Which mineral water has the most magnesium in Romania?
Borsec Carbogazificată leads with 101 mg/L, followed by Carpatina Light (97.6 mg/L) and Aqua Magnesia (94.2 mg/L). Values come from the official labels; the full top 10 is in the table above.
How much does the variant matter within the same brand?
A great deal: Carpatina Light contains 97.6 mg/L of magnesium, while Carpatina Plata has only 5.2 mg/L — same brand, different springs. Before buying, check the values on the label of the exact variant, not just the brand name.
When is a water "magnesian"?
The claim is permitted when magnesium exceeds 50 mg/L.
How much magnesium can mineral water contribute versus the daily requirement?
One litre of Borsec Carbogazificată provides 101 mg of magnesium — roughly a third of the reference value for adults, which EFSA places around 300–350 mg per day. Water does not replace a balanced diet, but it can complement it without calories.
What does a magnesium-rich water taste like?
At high concentrations, magnesium gives water a slightly bitter note — one of the reasons strongly mineralised waters have a more pronounced character. Milder options can be found further down the table.
All values are based on official mineral water labels and the h2oMatch database.
