The evaluation of concentrations of C, B 2 and Ve vitamins in 91 pregnant women in Moscow using noninvasive methods was performed. Vitamin concentrations were assessed by urine excretion of ascorbic acid, riboflavin and 4-piridoxal acid with a fasting morning urine sample. Vitamin C deficiency was found in 20.4% of the women surveyed, vitamin B 2 deficiency - in 27.4%. The vitamin B 6 deficiency was the most frequently detected (90%). Excretion of vitamins B 2, Be in the III trimester of pregnancy was lower compared with those in I and II trimesters. Excretion of vitamins B 2 and especially B 6 in women receiving vitamin complexes was higher compared with women not taking vitamins, which indicates better vitamin concentrations. Among women who received vitamin complexes, inadequate concentration of water-soluble vitamins was detected less frequently (the differences were significant for vitamin B 2) than among women who did not receive vitamin complexes.
