An optimal magnesium supply is important for the production of energy for the cells. Magnesium is also involved in the activation of several enzymes. In addition, it is necessary for the proper function of nerve and muscle cells. For the heart muscle in particular, Magnesium is of great importance.

Calcium is involved in many biological processes, e.g. blood coagulation. A good Calcium supply is also needed for healthy and strong bones.

Vitamin D₃ favours calcium fixation in the bones. Vitamin D₃ is produced by our own organism under the regular stimulation of sunlight on the skin. However, Vitamin D3 synthesis in the skin may be reduced if the skin is naturally dark, if it is covered with clothes or protected with a sunscreen.

Both Magnesium and Calcium are necessary for a normal muscular function and for the proper progress of several metabolic pathways.

Only one tablet Doppelherz® aktiv Magnesium + Calcium + Vitamin D₃ daily as a complement to a balanced diet supplies an adequate amount of these two minerals which help to stay healthy and efficient in times of higher physical or mental stress.
