two prenatal vitamins? — The Bump

two prenatal vitamins?

One of the doctors I work with & had twins herself mentioned today that I should start taking two prenatal vitamins daily since I'm expecting twins & am now in my second trimester. I never heard of it. Anyone do this?

Re: two prenatal vitamins?

  • I didn't. Ask your OB, but all I was told is to take an extra folic acid supplement (not a full prenatal vitamin) when I asked my OB.

  • Ask your OB. Mine had me take extra folic acid. Starting at 20 weeks, she also added extra iron.
  • Loading the player...
  • I asked my MFM at the beginning about double prenatal and he said no. He has me taking extra folate and has been watching my calcium, iron, vitamin D etc. via bloodwork. Everything dropped recently and I'm now anemic. They've added Iron supplements (none in my prenatal) and my vitamin D has dropped a third from week 14 to 18 so they've added that as well. Good luck!
  • I didn't take anything above and beyond a prenatal w DHA.

  • Like PP I was told to add extra folic acid, but nothing about another prenatal vitamin.

  • So far I take one prental one extra folic and now I am put on iron since my iron is super low
  • One of my OB's told me at my 20 week apt to take two but he's the only one. (I see a team.) honestly, I just take one. Sometimes I'll take 2 but not very often.
  • My MFM said not to take a second prenatal because they have vitamin A which you can overdose on. But she did put me on extra folic acid , magnesium, and zinc


  • I only take one, but I also take an additional folic acid, calcium, and vitamin d (and at night I take a probiotic and a colace.. because pregnancy.)  my DH is a big vitamin nut so he helped me keep track of all of it.

  • I normally have iron anemia so I take an iron. Took 1 prenatal and 1 folic. Have triplets.


    No periods due to 17 years of ballet and distance running after college.  Zero response to 2 months of Clomid, little response to Letrozole.  IUI left with 9 cysts = too many viable eggs due to age.  On to IVF.  Low dose of all meds still produced 37 mature eggs 12.6.11.  Froze due to overstimulation.

  • When i asked my doctor, she said one prenatal was fine. She,again this just for myself, prescribed me extra calcuim, iron and omega 3 vitamins. She did this with my last pregnancy too.not because i was missing vitamins i guess just so your body is getting enough.
  • I took one prenatal, additional folic acid and ended up on an iron supplement as well.  As one poster mentioned, you can OD on Vitamin A.
