Doppelherz aktiv Magnesium + Calcium + D3 Tablets supplies the body with essential nutrients for a greater resistance in times of physical or mental stress. An optimal supply with vitamins and minerals is very important for well-being and performance of the body. Magnesium and Calcium are two essential minerals which are used by the body for activating and maintaining many biological processes. Vitamin D3 regulates the Calcium uptake into the bones. Essential substances like Magnesium can�t be synthesised by the body and the storage is limited. Nowadays, food is mainly processed resulting in a lower intake of essential minerals like Magnesium. Storage and cooking lower the concentration of minerals in food as well. Also, an intake of laxatives and regular drinking of alcohol withdraws Magnesium from the body. Only one tablet daily in complement of a balance diet supplies an adequate amount of these two minerals which helps you stay healthy and efficient in times of higher physical or mental stress.
