Hi all, I'm currently trying to conceive. I have an underactive thyroid and take Levothyroxine. Just wondered if you can recommend any prenatal vitamins that have worked best for you? I know you have to leave at least 4 hours between taking Levo and prenatal vitamins.
Thank you.
I will add in some good information from Thyroiduk.org.uk about pregnancy. Some people might miscarry if hypothyroid, so I'll give you a link of how best to look after yourself and baby.

Just in case you are unaware of the procedure we should follow - to get the most accurate results -
Always get the earliest appointment - even if you have to book the test weeks in advance.
It is a fasting test (you can drink water) and allow a gap of 24 hours from last dose of hormones and test and take afterwards.
Always get a copy of your results from the surgery for your own records and post if you have a query.
I will give you a link from TUK which you might also find helpful.

Hi there, I’m following this thread too but both links you have posted about to Thyroid UK just seem to say “coming soon”. Is there another way to access this info? Many thanks!
Thanks for notifying me. I'll have a look to see if I can resolve it.
It could be due to TUK updating their information.
I am correct - due to site being updated no info is yet available.
I hope the following will be helpful:
Hi, thank you so much for replying. I will make sure I do this next time I have a thyroid test which will be in a couple of weeks. Thanks for the links, also with the food and drug interactions I noticed it says I should be wary of Iodine and the prenatal vitamin i'm taking has it in so think I will opt for another one without it.
Important to get FULL thyroid and vitamin testing so that you can see what your vitamin levels actually are
What vitamin supplements have you been taking up until now?
How much levothyroxine are you currently taking
Do you always get same brand
For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12
Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies
Presumably you have Hashimoto’s?
Ask GP to test vitamin levels
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Are you currently taking T3?
If/when also on T3, make sure to take last third or quarter of daily dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test
Is this how you do your tests?
Private tests are available as NHS currently rarely tests Ft3 or thyroid antibodies or all relevant vitamins

Hi, Thanks for the reply. I have been taking Vitabiotics Pregnacare (before conception) not been taking it long though. But feel a bit wary as it has iodine in and lots of other vits i'm not sure if this will effect levels although pharmacist says as long as i take 4 hours apart but think i will opt for one without it to be on the safe side.
I take 100mg and 75mg alternate days.
Yes it is usually the same brand that I have.
I don't know if I am Hashimoto and i don't take t3 just Levothyroxine.
Yes i will try my gp to test these but it's like getting blood out of a stone trying to contact them at the moment. Thank you for the lincs and info
