Yes. The use of Omega-3 fatty acids during pregnancy is highly documented and should be recommended. They have been shown to aid the baby's mental development and reduce the incidence of neurological conditions. They have also been shown to reduce the risk of post natal depression experienced by the mother after giving birth, and therefore their use during pregnancy may also lead to an increase in breast-fed babies. However, Cod Liver Oil should be avoided during this time due to its vitamin A content especially if other vitamin A containing supplements are being used.
