Fish oil does not cut postnatal depression risk

Taking fish oil capsules during pregnancy has no effect on maternal depression or development of the unborn child, research has shown.

Australian researchers found women who took daily fish oil supplements in the second half of pregnancy had the same risk of postnatal depression as those who did not.

Likewise, fish oil had no effect on the cognitive or language ability of children born to mothers who took the capsules.

To test the effect of DHA on outcomes, researchers recruited 2,399 women who were less than 21 weeks pregnant. Women were randomised to receive 800mg per day of DHA, or control capsules.

These women were scored for depression symptoms during the six months postpartum. A total of 726 children were tested for cognitive and language development at 18 months of age.

Researchers found mean scores for both depression and child development were the same between the two groups.
