Bottled Water With Minerals: Best Brands for Calcium, Magnesium and Electrolytes

Spain's Vichy Catalan tops the global table with ~3,050 mg/L TDS, followed by Germany's Apollinaris (~2,650 mg/L) and Gerolsteiner (~2,500 mg/L), and France's Contrex (~2,080 mg/L) — the highest-mineral still water. Georgia's Borjomi sits in the same tier with extremely high bicarbonate and sodium.

No. Natural mineral water gets its calcium, magnesium, sodium and bicarbonate from a single protected source — nothing is added. Electrolyte or fortified waters typically start with purified water and have minerals added back in measured amounts. Both can be hydrating, but the regulatory definitions and labelling rules are different.

For most healthy adults, yes — high-mineral waters are a useful source of calcium and magnesium. People on sodium-restricted diets should avoid high-sodium bottles like Vichy Catalan and Borjomi, and anyone with kidney conditions should consult a doctor before switching their everyday water to a high-TDS brand.

Contrex (France) leads with ~468 mg/L of calcium, followed by Ferrarelle (~365 mg/L) and Gerolsteiner (~348 mg/L). All three exceed the calcium content of most milk on a per-litre basis.

Apollinaris (~130 mg/L) and Gerolsteiner (~108 mg/L) are the magnesium leaders among widely-distributed brands. Specialty bottles like Donat Mg reach 1,000+ mg/L but are sold as a functional water rather than everyday hydration.

Mineral content is identical between still and sparkling versions of the same source — the carbonation does not change the calcium, magnesium or bicarbonate values. The bubbles are CO₂, which can slightly aid digestion but may also cause discomfort for people prone to bloating.
