The B vitamins are water-soluble vitamins and cannot be stored in the body. Any surplus is excreted in the urine. Humans are therefore dependent on a regular exogenous supply. The group of B vitamins includes eight vitamins: B1, B2, B3, B5, B6, B7, B9 and B12. Their tasks are diverse and complex. Vitamin B12 plays a special role, as it can be absorbed almost exclusively through animal foods. The vitamins of the B group are important in connection with hormone formation, they influence blood circulation, are involved in carbohydrate, protein and fat metabolism and contribute to blood formation and healthy nerve function.
Magnesium performs vital functions in the body. It is involved in energy metabolism, muscle and nerve function and is responsible for muscle contraction, for communication between nerve cells and between nerve and muscle cells, and for heart activity. The mineral is also involved in the formation of bones and teeth. Furthermore, it is essential for fat and carbohydrate metabolism. Only about 30 to 50 percent of the magnesium supplied daily in the diet is absorbed by the body.
Salt, i.e. sodium chloride (NaCl), is a vital substance for humans. Table salt is the main source of sodium and chloride, which are essential for fluid balance, the nervous system and the regulation of blood pressure. Sodium chloride protects cells from dehydration and is responsible for the transmission of signals in nerve cells. No cell in our body could exist without salt.
