Do Omega-3 Supplements in Pregnancy Support Baby’s Brain Development?
This systematic review pulled together findings from 33 published articles, mostly randomized controlled trials, that looked at whether omega-3 fatty acid supplements taken by mothers during pregnancy and/or breastfeeding were linked to differences in their children’s brain and developmental outcomes.
Among the 8 trials where mothers took DHA and EPA supplements during pregnancy only (roughly 200-2200 mg/day DHA and up to 1100 mg/day EPA for about 20 weeks), 5 of them found at least one measure showing improved cognitive development in the child, with gains ranging from about 6% to 11%.
Evidence for other outcomes like language, motor skills, vision, social-emotional development, academic performance, or risk of conditions such as ADHD or autism was inconsistent or too limited to draw conclusions. The same was true for supplementation during breastfeeding alone or during both pregnancy and lactation combined. The reviewers also noted that study populations underrepresented lower-income groups, adolescents, and diverse racial/ethnic backgrounds.
What this means for you
This review suggests that omega-3 supplementation during pregnancy may be associated with modest improvements in some measures of a child’s cognitive development, though the overall evidence base is still limited and more diverse, well-designed research is needed before firm conclusions can be drawn.
