JOCELYN HAS BEEN FEATURED ON:

Supplementing with folic acid in the first trimester has become ingrained in the consciousness of pregnant women, who need adequate folate stores to reduce the chance of neural tube defects in the developing fetus.

A recent study has found another important component of neural tube closure: docosahexaenoic acid (DHA).

DHA is an omega-3 fatty acid, and is most abundant in the brain and eyes. Omega-3 supplementation (EPA and DHA) is most recommended in the final trimester of pregnancy to prevent pre- term labour and preeclampsia, to promote fetal neurological and visual development (including better IQ, language, reasoning and hand-eye coordination), to help lower allergies and eczema in newborns, to shorten duration of coughs and colds in newborns, and to prevent post–partum depression.

This study, however, makes the argument that DHA is just as important as folate for neural tube closure. Maternal DHA is mobilized rapidly during the first month of gestation prior to neural tube closure, demonstrating that supplementing with DHA pre-pregnancy and/or in early pregnancy may be an important addition to a maternity care plan.

I hope you have found this helpful, and do let me know if you have any questions!
