Calcium in mineral water

Quick Facts: Calcium


Calcium is a mineral, and its chemical designation is Ca2+. It must be consumed daily as the body cannot produce it.


Calcium is quantitatively the most represented mineral in the body. 99% of calcium is stored in bones and teeth (approx. 1 kg).

Daily requirement

Adults: 800 mg. Increased requirement for adults over 50 years of age, pregnant and breast-feeding women: up to 1,200 mg.

The significance of calcium

All minerals play important roles in your body. However, calcium has several particularly important roles. 99 percent of calcium (approx. 1kg) is stored in your skeleton – it is quantitatively the most important mineral in your bones and teeth enamel.

Our bodies are not able to produce the mineral nutrients we need, which is why it's necessary for us to obtain them from our food and beverages. Mineral Water contains mineral nutrients like calcium in a dissolved form - this increases its bioavailability, enabling our bodies to absorb and use this vital nutrient more readily.

Recommended daily requirement

Your body cannot produce calcium and so you need to consume it daily via food and beverages. For the average adult, the recommended daily calcium requirement is 800 mg per day. Children and adolescents need somewhat more while they are growing. Both pregnant and breast-feeding women also have a higher requirement. For these groups, a daily calcium intake of up to 1,200 mg is recommended. It is recommended that calcium intake should not exceed 1,500 mg of calcium per day.
