Calcium is a mineral that keeps bones and teeth stable; that's where almost 100 % of the calcium in the body is stored. In addition, calcium is an important factor in blood clotting and is fundamental to the function of every cell in the body: It stabilises the cell walls and is involved in signal transmission in the cell as well as in the transmission of stimuli in the nervous system (e.g. hearing, seeing, touch sensitivity) and in the muscles.
The No. 1 source of calcium is milk and dairy products. Furthermore, some types of vegetables, such as broccoli, kale and rocket, berries as well as calcium-rich mineral water (150 mg / litre) and various types of nuts (e.g. hazelnuts and Brazil nuts) are good sources of calcium.
