Calcium is a mineral necessary to the buildup and upkeep of bones and teeth. Calcium additionally supports the flow of impulses between nerves and muscles. Whether it be blood coagulation, the energy metabolism or the digestive system: Calcium plays a part in many essential bodily functions.

Calcium requirements depend on age. The more intense the growth of the skeleton, the higher the daily dose needs to be. Children especially require calcium to ensure the healthy development of the bones. 

The German Food Society (Deutsche Gesellschaft für Ernährung (DGE)) recommends a dose of up to 1,200 mg of calcium a day for children.


The daily calcium requirement of an adult is approximately 800 mg.

Gerolsteiner Sparkling and Gerolsteiner Medium contain valuable calcium naturally: At 348 mg/l both of them supply the body with this valuable mineral on a daily basis. Gerolsteiner Naturell contains 140 mg/l.
