• Mixed is a part of lecithin, plays a role in the synthesis and metabolism of phospholipids in the liver, is a source of free methyl groups, acts as a lipotropic factor.
• Vitamin B6 participates in the maintenance of the immune response, inhibition and excitation processes in the central nervous system, in the conversion of amino acids, in the metabolism of tryptophan, lipids and nucleic acids, contributes to the normal formation of erythrocytes, maintenance of the normal level of homocysteine ​​in the blood. Insufficient intake of vitamin B6 is accompanied by a decrease in appetite, a violation of the condition of the skin, the development of homocysteinemia, anemia.
• Vitamin B12 plays an important role in the metabolism and conversion of amino acids. Folate and vitamin B12 are interrelated vitamins and are involved in blood formation. Lack of vitamin B12 leads to the development of partial or secondary folate deficiency, as well as anemia, leukopenia, thrombocytopenia.
• Vitamin D maintains homeostasis of calcium and phosphorus, carries out the processes of bone mineralization. Lack of vitamin D leads to impaired metabolism of calcium and phosphorus in bones, increased demineralization of bone tissue, which leads to an increased risk of osteoporosis.
• 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.
• potassium is the main intracellular ion that takes part in the regulation of water, acid and electrolyte balance, participates in the processes of nerve impulses, pressure regulation.
• 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.
• Selenium – an essential element of the antioxidant defense system of the human body, has an immunomodulatory effect, participates in the regulation of the action of thyroid hormones. Deficiency leads to Kashin-Beck disease (osteoarthritis with multiple deformities of the joints, spine and extremities), Keshan disease (endemic myocardiopathy), hereditary thrombastenia.
