title: [The vitamin C, B12 and folate allowances of pregnant women in Moscow].
abstract: A dietary supply of vitamins was studied in 212 pregnant women for 11 months. Mean blood levels of vitamins were found subnormal, the percentage of the women with vitamin deficiency increased. Especially inadequate was supply of folate followed by vitamin C. Intake of 1 dragee a day of polyvitamins "Gendevitum" improved the vitamin status of the examinees with the best results obtained in the first trimester. Folate and B12 levels decreased with advance of pregnancy irrespective of polyvitamins administration. Vitamin C supply was better in summer and autumn, folate levels were higher in winter and spring. It is suggested that vitamins C, B12 and folate deficiency observed in pregnancy should be corrected.
