How do we calculate your recommended daily intake of minerals? Excerpt from daily reference values and reference daily intakes listed by the FDA (USA) and Gerolsteiner regular analysis. Daily requirement of an adult: Calcium (Ca2+) 1300 mg* Magnesium (Mg2+) 420 mg* Bicarbonate (HCO 3 -) - Potassium (K+) 4.700 mg* Sodium (Na+) 2.300 mg* Chloride (Cl-) 2.300 mg* Sulfate (SO 4 2-) - * U.S. Food and Drug Administration Regulations at 21 C.F.R 101.9 - Reference Daily Intakes and Daily Recommended Values; percentages are based on mineral content per liter. For the calculation of the recommended daily mineral amount you can choose between EU (European Union) and DGE (German Society for Nutrition) recommendations and the recommendations stipulated by the United States Food and Drug Administration (FDA).

What is Purified Water

Purified water does not need to be of natural origin. It is a fabricated mixture of tap water and possibly waters such as salt water or mineral water. As purified water is not bound to a particular spring, it can be produced and bottled anywhere and can be offered in unbottled form, such as on tap. Unlike mineral water, it does not need any kind of official seal of approval.

What is Spring Water

Spring water is also obtained from underground water springs and is bottled directly at the spring. However, its mineral content does not need to be consistent, nor does it require an official seal of approval. Just like water from your tap, spring water must have no odor, an acceptable taste and low microbiological contamination.
