The main supply of trace elements
In addition to vitamins, macro- and microelements are involved in the structure of all body systems. For example, the cause of drowsiness, depression and weakness can be a decrease in hemoglobin, which is associated with a lack of iron. In its natural form, it is found in meat, buckwheat, liver, egg yolk. Other important micronutrients, the need for which increases in the spring:

Calcium. Strengthens bones, teeth and nails. It has a beneficial effect on blood coagulation, muscle contractions, cell division, and the release of hormones.
Iodine. Responsible for the thyroid gland, liver and kidney function. With a shortage, goiter (an enlarged thyroid gland), weakness in the muscles, and a slowdown in the development of mental abilities occur.
Magnesium. Its deficiency causes calf cramps, palpitations, nervousness and frequent headaches. Reduces stress levels and affects hormonal balance.
Zinc. Regulates metabolic processes and the reproductive system. With a lack of an element, white spots appear on the nail plates, fatigue, and allergies.
Cobalt. Promotes the production of insulin and vitamin B12. An insufficient amount of cobalt leads to anemia and drowsiness.
Copper. Responsible for the absorption of iron. With a deficiency, dermatitis, anemia develop, hair weakens and weight decreases.
Fluorine. Takes part in the formation of tooth enamel and tissues. The lack of an element leads to the constant development of dental caries.
Vitamins and macronutrients are absorbed better when interacting, so it is recommended to use them in a complex way. Some combinations will bring maximum benefit, complementing each other: zinc and vitamin D, iron and vitamin A, selenium and vitamin E, magnesium and vitamin B6.
