To the Editor: Dr Makrides and colleagues1 reported that supplementation with 800 mg per day of DHA and 100 mg per day of eicosapentaenoic acid in pregnant women neither lowered levels of postpartum depression nor improved mean cognitive and language development scores in their offspring, compared with a control group receiving vegetable oil capsules. In addition, girls exposed to DHA in utero had poorer mean adaptive behavior and language scores.
