• Vitamin B1 is part of the most important enzymes of carbohydrate and energy metabolism, which provide the body with energy and plastic substances, as well as the metabolism of branched-chain amino acids. Lack of this vitamin leads to serious disorders of the nervous, digestive and cardiovascular systems.
• Vitamin B2 participates in redox reactions, enhances the color sensitivity of the visual analyzer and dark adaptation. Insufficient intake of vitamin B2 is accompanied by a violation of the condition of the skin, mucous membranes, impaired light and twilight vision.
• Vitamin B5 participates in protein, fat, carbohydrate metabolism, cholesterol metabolism, the synthesis of a number of hormones, hemoglobin, promotes the absorption of amino acids and sugars in the intestine, supports the function of the adrenal cortex. Lack of pantothenic acid can lead to damage to the skin and mucous membranes.
• Vitamin PP participates in redox reactions of energy metabolism. Insufficient vitamin intake is accompanied by disruption of the normal state of the skin, gastrointestinal tract and nervous system.
• Calcium is the main component of our bones, acts as a regulator of the nervous system, participates in muscle contraction. Calcium deficiency leads to demineralization of the spine, pelvic bones and lower extremities, increases the risk of osteoporosis.
• Phosphorus takes part in many physiological processes, including energy metabolism, regulates acid-base balance, is a part of phospholipids, nucleotides and nucleic acids, is necessary for the mineralization of bones and teeth. Deficiency leads to anorexia, anemia, rickets.
• Iron is a part of proteins of various functions, including enzymes. Participates in the transport of electrons, oxygen, ensures the course of redox reactions and activation of peroxidation. Insufficient consumption leads to hypochromic anemia, myoglobin-deficient atony of skeletal muscles, increased fatigue, myocardiopathy, atrophic gastritis.
• Manganese participates in the formation of bone and connective tissue, is part of the enzymes involved in the metabolism of amino acids, carbohydrates, catecholamines; essential for the synthesis of cholesterol and nucleotides. Insufficient consumption is accompanied by a slowdown in growth, disorders in the reproductive system, increased fragility of bone tissue, disorders of carbohydrate and lipid metabolism.
