The water is rich in magnesium, calcium and other vital minerals and significantly helps improve our health and treatment.

Natural mineral waters can be rich in vitally important minerals. Based on the quantity and combination of these elements, different types of natural mineral waters have been identified, for example:

  • calcium mineral waters,
  • magnesium mineral waters,
  • sodium-hydrogen carbonate mineral waters,
  • magnesium-sodium-hydrogen carbonate-sulphate waters.
These waters usually also contain dissolved carbon dioxide. Natural mineral waters can aid our health if they contain a certain concentration of minerals. Their advantage lies in the fact that their contents are easily accessible to our bodies; dissolved in the water, they are immediately available to our organism.

Carbon dioxide - carbonic acid

Carbon dioxide is an important element found in some natural mineral waters. The advantage of these waters is precisely in their carbon dioxide content, as carbon dioxide acts as a natural stabiliser for mineral water. It enhances the feeling of refreshment and also makes drinks seem colder than they actually are. A smaller part of the carbon dioxide chemically bonds with the water to form carbonic acid, while a larger part is dissolved in the water in the form of a gas (bubbles).



Professional literature contains a great deal of information about the effects of the sulphate ions found in natural mineral waters on metabolic processes in the body. The body has a hard time reabsorbing sulphates, which leads the latter to cause an osmotically controlled secretion in the stomach and intestines. The osmotic effect is particularly enhanced if magnesium ions are present. Besides secretions in the stomach, waters with a high sulphate salt content also cause increased blood flow to the mucus lining of the stomach. The results of clinical studies seem to indicate that the normalisation of stomach secretions can be achieved through the prescribed drinking of waters of this kind.

Hydrogen carbonate

Hydrogen carbonate ions bond to stomach acid in equal amounts. The carbon dioxide released during neutralisation affects the reflexive stimulation of secretions in the stomach. Drinking natural mineral waters with a higher content of hydrogen carbonate ions has a favourable effect on problems pertaining to the secretion of stomach acid. Natural mineral waters containing over 1300 mg of hydrogen carbonate ions per litre can be used to relieve or even cure deviations in the acid–base homeostasis in different parts of the body. By introducing hydrogen carbonate ions, an excess of base occurs in the organism, increasing base reserves.
