Gerolsteiner Mineral Water: Mineral Content, Benefits, Taste and pH
Gerolsteiner is one of the most highly mineralized bottled waters sold worldwide. Retail and brand references commonly list it at around 345 mg/L calcium, 100 mg/L magnesium, 1,800 mg/L bicarbonate and 115 mg/L sodium — far above what you find in a standard spring water.
What is Gerolsteiner water?
Gerolsteiner is a naturally carbonated mineral water from the volcanic Vulkaneifel region of Germany. The water rises through dolomite rock, picking up calcium, magnesium and bicarbonate on the way up. It is bottled at source and sold internationally as Sparkling (Sprudel) and Medium (Medium), with the brand reporting around 2,479 mg/L of total dissolved minerals.

Exact values can vary slightly between batches and between Sparkling and Medium versions.
Why Gerolsteiner tastes stronger than regular bottled water
Most mainstream bottled waters have a TDS under 300 mg/L. Gerolsteiner sits near 2,479 mg/L. That high mineral load produces a fuller, slightly mineral-salty taste, with a bicarbonate "bite" on the finish. The natural carbonation adds carbonic acid, which sharpens the flavor and is one reason Gerolsteiner pairs well with food.
Is Gerolsteiner high in minerals?
Yes. Gerolsteiner is classified as a high-mineral water. Its calcium and magnesium levels are among the highest of any widely available bottled water, and its bicarbonate content is exceptional. For comparison, Evian sits near 309 mg/L TDS and Fiji near 222 mg/L — Gerolsteiner is roughly 8–10x more mineralized.
Is Gerolsteiner high in sodium?
Gerolsteiner contains about 115 mg/L of sodium. That is higher than typical low-sodium waters (under 20 mg/L) but still moderate compared with sodium-rich mineral waters like Vichy Catalan or Staatl. Fachingen. A 500 ml glass delivers roughly 58 mg of sodium — a small fraction of the 2,300 mg daily limit recommended by the FDA. People on strict low-sodium diets should still account for it; see our low-sodium water guide.
Is Gerolsteiner water bad for you?
For most healthy adults, no. Gerolsteiner is a regulated natural mineral water and its mineral profile actually contributes meaningful calcium and magnesium to the diet. People with chronic kidney disease, severe hypertension or those on a clinical low-sodium plan should ask their doctor before drinking high-mineral water daily. It is also not the best pick for baby formula because of the high mineral and sodium load.
Gerolsteiner vs regular spring water
| Metric | Gerolsteiner | Typical US spring water |
|---|---|---|
| TDS | ~2,479 mg/L | 50–250 mg/L |
| Calcium | 345 mg/L | 10–40 mg/L |
| Magnesium | 100 mg/L | 2–8 mg/L |
| Sodium | 115 mg/L | 2–15 mg/L |
| Carbonation | Natural sparkling | Still |
| pH | 6.5 – 7.6 | 7.0 – 7.8 |
Choose Gerolsteiner when you want dietary minerals or a food-friendly sparkling water. Choose a regular spring water for neutral all-day sipping.
