This is how calcium, magnesium work

Thanks to the one-of-a-kind geographical nature of the bedrock in the Volcanic Eifel, Gerolsteiner is completely pure, has a balanced mineral content and is one hundred percent natural. Water that has filtered down through layers of bedrock gathers in deep aquifers, 200 meters beneath the ground. Here, the water remains protected from impurities and environmental contamination. In order to preserve its natural quality, Gerolsteiner is bottled directly at its source – pure and authentic from its origin.

Whether at work, after sport or simply in between – Gerolsteiner mineral water is the perfect companion in everyday life. It quenches thirst and at the same time provides the body with valuable minerals and trace elements, which the body cannot generate itself. Just 1 liter of Gerolsteiner Sparkling satisfies one third of the daily calcium requirement and more than a quarter of the magnesium requirement.

Over time water seeps down through the mineral-rich layers of dolomite bedrock, absorbing minerals and carbonic acid, before collecting in deep aquifers as Gerolsteiner Mineral Water. From the depths of the Volcanic Eifel to every cell of your body: one litre of Gerolsteiner Sparkling Mineral Water contains over 2,500 mg of minerals and trace elements.

The unique balance of minerals in Gerolsteiner ensures their bioavailability. The minerals are already dissolved, so your body can absorb them quickly. The ratio of minerals, especially calcium and magnesium, also enables maximum usage. In mineral water, the bioavailability of calcium is 84% and that of magnesium is 92%. As a comparison, in a banana, the bioavailability of calcium is only 38% and that of magnesium is a mere 29%.
