**2. The role of magnesium in the human body and its application in medicine**

Magnesium is called an element of life, because it participates in many processes of the human body. It is necessary to maintain proper homeostasis, i.e. the proper functioning of the human body. It is estimated that there are approximately 22–26 g of magnesium in the human body [13]. It should be mentioned, that both the value and the range of the concentration of an element in the human body depends on the age, sex, absorption of the elements or even diet. The World Health Organization (WHO) has issued standards defining the daily demand for the element [14, 15].
