I probably should find a vegetarian DHA. I've been taking fish oil, which, although this brand claims to be pure, probably that's not true of any fish oil. Hopefully I haven't done damage to the baby. Unfortunately, prenatal vitamins I can't do. I have developed awful reactions to supplemental folate (both folic acid and 5-mthf) possibly because I supplemented it for so long that my serum folate tested ridiculously high, which resulted in side effects. I've just stopped multivitamins completely and am instead eating copious amounts of green leafies and supplementing select individual vitamins.
