Magnesia brand is owned by Mattoni 1873 in Czech Republic.

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 into 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. The Slavkov Forest is a protected landscape area extending over 606 square kilometers around the source of Magnesia.
