There is increased interest in the relationship between vitamin D and postpartum depression. This review evaluates the 3 studies that have examined associations between prenatal vitamin D status and postpartum depressive symptoms. Based on the evidence, there is an association between low prenatal vitamin D levels and an increased risk of postpartum depressive symptoms. Vitamin D at a dose of 2000 IU/d may be a convenient choice to correct serum levels safely and reduce the incidence of depressive symptoms. Health care professionals should facilitate adequate vitamin D intake during pregnancy to mitigate depressive consequences of deficiency in the postpartum period.
