Natural vitamin E supplementation during pregnancy in rats increases RRR- α-tocopherol stereoisomer proportion and enhances fetal antioxidant capacity, compared to synthetic vitamin E administration

Conclusions: Both natu ral and synthetic sources of vitamin E showed similar bioavailability. Still, NVE supplementation increased the proportion of RRR-αT and promoted higher antioxidant activity in fetal plasma at birth. Placental SR-B1 might be involved in the stereoselective transfer of RRR-αT stereoisomer across th e placenta and may improve αT bioactivity in the fetus.
