Magnesium is an important mineral that is essential for numerous functions in the body. Magnesium plays a crucial role in the heart muscle in particular, as it is essential for the contraction of the heart and therefore for the pumping function. A magnesium deficiency can therefore have serious consequences for heart health. Symptoms such as cardiac arrhythmia, heart cramps and even heart attacks can be the result. It is therefore important to get enough magnesium through your diet or, if necessary, through dietary supplements. The need for magnesium can be particularly high in people who do a lot of sport or are under stress. Older people and pregnant women also often have an increased need for this important mineral. To maintain heart health, it is therefore important to ensure an adequate supply of magnesium. A balanced diet with magnesium-rich foods such as nuts, wholegrain products, green vegetables and bananas can help to cover the requirement. A well-functioning heart muscle is essential for the health of the entire body.
