Magnesia natural mineral water comes from the protected landscape area of the Slavkov Forest. On its journey from the depths of nature Magnesia has to make its way through a layer of serpentine – a rock especially rich in magnesium. Magnesium is released from the water with the help of carbon dioxide, a remnant of past volcanic activity. The combination of serpentine and carbon dioxide is so rare that, in Europe alone, it can be found only on a few square kilometers of the Slavkov Forest. Thanks to this combination, Magnesia acquires its unique high content of natural magnesium and simultaneously low content of sodium with overall medium mineralization.
