Honestly I think prenatals can be a real waste of time for some people. If you want vitamins to actually target what you need, you need to get tested. I got blood
tests which found out I was low in Mg, Zn, Iron, Vit D, B12. Plus took a gene test for MTHFR gene which showed I don't even absorb folic acid, so I need other forms of folate. I take the specific vitamins/minerals for what I'm deficient in. If I just took a regular prenatal it would really do jack all.
