Mineral waters with the most calcium in the UK — top 5 by calcium content.
The ranking covers natural mineral waters available on the UK market listed in the h2oMatch database.
| Water | Calcium (mg/L) | Magnesium (mg/L) | Fixed residue (mg/L) |

FAQ
Which mineral water has the most calcium in the UK?
Aqua Carpatica leads the UK market with 288 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 in the UK is rich in both calcium and magnesium?
Aqua Carpatica stands out clearly: 288 mg/L of calcium with 84.7 mg/L of magnesium, the highest value in both UK rankings. Badoit (153 and 80 mg/L) is the other strong combination.
When may a water carry the indication 'contains calcium'?
Under the natural mineral water rules, the indication ‘contains calcium’ applies above 150 mg/L.
Is calcium from mineral water absorbed by the body?
Published studies indicate that calcium from mineral water is well absorbed by the body. A water with a high calcium content can contribute to daily dietary intake.
Why is the UK's highest-calcium water an import?
British springs mostly rise through geology that yields lightly mineralized water, so domestic brands rarely exceed 100 mg/L of calcium. Hildon, at 97 mg/L, is the strongest home-grown entry. The market leaders above it are imports from Romania, Italy and France.
All values are based on official mineral water labels and the h2oMatch database.
