Microelements, despite their small amount in the body, play a key role in the functioning of each cell, affecting metabolism, hormone synthesis, the functioning of the immune system and nervous tissue.<\/p>\n<p data-start=\"657\" data-end=\"929\">Without sufficient levels of these elements, normal functioning of the heart, brain, muscles, as well as the processes of tissue growth and repair become impossible. At the same time, an excess of some trace elements can have a toxic effect, which makes the analysis especially important in preventive medicine.<\/p>\n<h2 data-start=\"547\" data-end=\"594\">What are micronutrients and why are they important?<\/h2>\n<p data-start=\"596\" data-end=\"833\">Micronutrients are chemical elements that the body receives with food and water in small quantities, but they are crucial for life. These include iron, zinc, iodine, selenium, copper, manganese, cobalt, chromium, and others.<\/p>\n<ul data-start=\"834\" data-end=\"1232\">\n<li data-start=\"834\" data-end=\"905\">\n<p
