[Effects of multivitamin preparations enriched with Fe, Zn and Se on the selenium status of pregnant women].

Se status of Moscow pregnant women was studied. The 13% decrease of Se up to the 30 week and the stability of GSHPx activity during all period of pregnancy were shown to be typical. No influence was found of the polyvitamine preparation action on Se status of women. The consumption of 30 mkg/day of Se during the pregnancy increased 2 times the GSPHx activity and conserved the serum selenium level.
