The benefits of taking folic acid or another equivalent form of Folate are now widely known, particularly its role in minimising the chance of anomalies with babies’ spines. And DHA is starting to get lots of recognition and press as well. A good maternal supply of DHA is crucial throughout pregnancy, particularly during the first 12-16 weeks of pregnancy when your baby’s brain and nervous systems are starting to develop. It’s important during the third trimester too (28 – 40 weeks) as this is when maximum brain development occurs. 70% of the nourishment your baby consumes during this period goes towards it.
