Abstract

Vitamins are obligatory nutrients to the developing fetus, these compounds being obtained from the maternal blood through placental transport. The strict importance of vitamins to fetal and pregnancy health is the motor for the current and emerging research on the molecular mechanisms of placental vitamin transport. This mini-review summarizes recent findings concerning the placental transport of the B-vitamins folate and thiamine.
