Pregnancy requires lots of essential fatty acids.

Since fish can be contaminated and limited for pregnant women, flax oil remains a good substitute. Women convert this to long chains well, for the fetus to develop the nervous system.

Some prenatals now have DHA in them as well. You can buy algae grown EFAs now too, to boost your levels and help your baby. There is an OTC form called Expecta.

Boosting EFAs now will help PN too. Marlene's advice about B12 is good as well. Many babies are born to mothers low in B12 and suffer as a result.

Make sure you have adequate folate. Good food sources, and vitamins.

People with the MTHFR mutation, need the methylated forms of B12 and folate. Most commercial products contain, synthetic forms and if you are are one of the MTHFR errors, you will not be making much progress yourself or for your baby.

DNA tests for this are on the net and doctors should be doing it IMO today, with what we know about this serious flaw in some people's genetics. It can be easily and inexpensively fixed if present. Both products are OTC today. (back a few years, this was not available, but now there is no excuse to fix it if present).
