For muscles, nerves and energy metabolism The challenges of everyday life and physical exertion from work or sports demand energy, muscle strength, and nerve function. An optimal supply of vitamins and minerals is therefore essential for our well-being and performance. Magnesium is an essential mineral that the body cannot produce itself. Furthermore, its storage capacity is limited. The high degree of food processing nowadays can mean that the amount of magnesium absorbed through food is not always optimal. Additional losses can occur during food preparation. Regular alcohol consumption also depletes the body of magnesium. Good sources of magnesium include whole grain products, legumes, many vegetables, as well as liver, poultry and fish. Magnesium contributes to normal energy metabolism and to the normal function of the nervous system and muscles. Vitamin B1 also contributes to normal heart function and, like vitamins B6 and B12, plays a role in the normal function of the nervous system. Vitamins B6 and B12 contribute to the normal formation of red blood cells, which are responsible for transporting oxygen in the blood. They also contribute to the normal function of the immune system, which can be particularly challenged during physical activity. Folic acid plays a role in normal cell division and blood formation. Together with vitamins B6 and B12, it contributes to normal homocysteine ​​metabolism.
