Sufficiency of 58 employees of a thermal power plant (47 men and 11 women aged 21 to 64 years, body mass index - 27.0±5.8 kg/m 2 ), with vitamins A, E, D, B 6 , B 12 , folic acid and carotenoids (content in the blood plasma) and vitamin C (urinary excretion) was conducted in winter (February 2015). All surveyed workers were sufficiently supplied with vitamins A, B 6 , B 12 and folic acid (a reduced level was detected in 0-9%). Insufficient supplying with vitamin E had 19% of the workers (and only men), vitamin C - 44%, vitamin D - 61%, carotenoids - 93%. Only 5% persons were sufficiently provided with all 6 vitamins. A combined deficiency of two vitamins had 38% of them, three - 22%, four - 16%. Simultaneously reduced plasma level of two antioxidants was observed in 36% of subjects, three - in 12%. Significant positive correlation (p <0.05) was detected between plasma levels: total cholesterol and retinol and β-carotene; tocopherol and total cholesterol, triglycerides, low density lipoprotein cholesterol; between the concentration of vitamin D, and high density lipoproteins; levels of retinol and tocopherol and β-carotene. In parallel intake of vitamins C, A, B 1 , B 2 and niacin has been assessed by calculation of the frequency of food consumption during the previous month. Reduced relatively recommended daily intake of vitamins A, C has been found in approximately half of the surveyed, niacin, vitamin B1 and B 2 - in 70-80%. Comparison of the data on the availability of vitamins C and A, obtained by calculation of vitamin intake and biochemical methods gave identical results in 55 and 60% of cases, correspondingly. The lack of vitamins has been detected more frequently by assessing dietary intake.
