In a rat model, following exposure to rat folate receptor alpha antibodies (FRαAb) during gestation, FRαAb accumulates in the placenta and the fetus and blocks folate transport to the fetal brain and produces behavioral deficits in the offspring. Although studies conducted since that time do not demonstrate a clear protective association (possibly because of food fortification effects, study design flaws, or inadequate sample sizes) [142], the U.S. Preventive Services Task Force recommends that all women who are planning to become or capable of becoming pregnant take a daily supplement containing 400 to 800 mcg folic acid starting least 1 month before conception and continuing through the first 2 to 3 months of pregnancy [37].
