I was taking a fairly similar lot of vitamins to you before getting pregnant. What follows is my opinion based on what I’ve heard, as opposed to a definitive medical answer!
If you were deficient in folic acid, it is possible that you have the MTHFR mutation. This mutation means that a person has difficulty processing folic acid. It can lead to miscarriages. The only way to find out if you have it is to have a genetic test.
However, I think that people who do have the mutation treat it by taking methylfolate instead of folic acid, because that is already broken down into a form that the body can use. Some people who have two copies of the gene also take baby aspirin throughout their pregnancy, although if you decided to go down this route you definitely need to get it oked by a professional!
Apparently taking folic acid can block the receptors which process the methylfolate, so I decided to find a prenatal vitamin which didn’t contain any folic acid, to be on the safe side. (I don’t know if I have the MTHFR mutation, but I have some risk factors, and it’s so easy to replace folic acid and so hard to deal with a miscarriage, so I’ve just gone with it.)
The prenatal vitamin I went with was Cytoplan Pregna-plan. I didn’t like the amounts of vitamins they included - some are double the daily recommended dose - so I’ve only taken one tablet daily instead of the recommended two. This means they have given me 200μg of methylfolate per day, which I supplemented with my 400μg methylfolate tablets every day for the first 12 weeks. (After 12 weeks excess folic acid can be a problem, so I’m just on the tablet daily now.)
However, these tablets taste and smell absolutely dreadful. For the first 12 weeks I actually found I couldn’t swallow them every day, so a lot of the time I just used the methylfolate and, if I could manage it, vitamin D. Government guidelines say folic acid and vitamin D are all you need, so I wasn’t worried about that. Now I’m past 12 weeks, I can swallow them just fine. I will be trying to get a different brand if I become pregnant again, though!
I stopped Co-q-10 when I became pregnant. Maybe research for yourself (or wait for a different opinion), but I think maybe it would be better to stop the insotol. Some people do carry on with Co-q-10 throughout their pregnancy, though. I think maybe older women, mostly?
I think I’d probably stop the extra B vitamins. Having said that, I take a Floradix equivalent, which has B vitamins and iron in (to keep my iron levels high - iron tables sound like a nightmare, and I’d rather not let it get to that! I think you can’t use Floradix to treat an existing problem, but it is probably helpful in preventing one).
If you do find a nice prenatal vitamin without folic acid in, please do let me know! I’ll need to buy some more in about 2 months, and it would be fun to have something tastier!
Good luck! Keeping my fingers crossed for you!
