Magnesium is one of the most important minerals for our bodies. It plays a crucial role in enzymatic processes in the body. Not only adults, but also children need certain amounts of magnesium to stay healthy (1). In particular, magnesium promotes relaxation, concentration and the immune system. Children can sleep better and have healthy teeth and bones. Magnesium also reduces restlessness, fatigue and muscle cramps. Unfortunately, we cannot produce magnesium ourselves in the body. We get magnesium from various foods, but in case of increased need and deficiency, we can also take medication.
