WAYS OF CORRECTION OF VITAMIN SUFFICIENCY AND ADVANTAGES OF MULTIVITAMIN SUPPLEMENTS

Background. About 22% of the surveyed adult population in Russia has a combined deficiency of vitamins (mostly D, B 2 and beta-carotene). The purpose of the study was to search for effective ways to optimize the consumption of vitamins by the population. Material and methods. A review of the literature was carried out using the databases Russian Science Citation Index (RSCI), CyberLeninka and Pubmed. Results. The existence of inter-vitamin metabolic interconnections with a lack of one vitamin can lead to the development of functional deficiency of another vitamin and make it more difficult to eliminate polyhypovitaminosis. Inclusion of fortified foods and meals in the diet as well as intake of vitamin-mineral supplements are reliable ways of enriching the diet with vitamins. Higher doses of vitamins allow achieving optimization of vitamin supply in a shorter period. Conclusions. To eliminate polyhypovitaminosis multivitamin complexes should be taken in doses exceeding the physiological requirement of the organism for a long time.
