Each bar is out of 10 for that property. Editorial score, not a health rating. How scores work →
Source kind: official brand report. The report's own 'typical mineral analysis' table disagrees with its lab table (it shows chloride 3.0, magnesium 0.061, sulfate 4.9); the lab product table (Eurofins) is used, pH and TDS from the typical table. Bicarbonate is printed with the same value as alkalinity; copied as published. The report calls it 'natural deep well water'.
How it stands out
- Sodium is 6.1 mg/L, under the 20 mg/L level the UK/EU uses for “suitable for a low-sodium diet” on natural mineral water labels.
UK/EU label thresholds met
