Can u take prenatal vitamins also folic acid an fish oil at once?

Yes- a good idea!: Most prenatal vitamins contain Folic Acid but it is perfectly safe to take more. One third of the population have difficulty converting synthetic Folic Acid to its active form, l-5-methyltetrahydrofolate (folic acid) (l-5-mthf) so i advise taking that form of folate (folic acid) in addition to a prenatal to be safe. Fish oil contains dha, essential for having a healthy child, so i strongly advise taking fish oil as well.
