B complex while hypothyroid?

I want to get your thoughts on the kind of supplements I can take while having under active thyroid? I am particularly interested in B complex as it helps boost energy levels. Please share you experience , if you are using certain supplements. Also is multivitamin supplements safe while using medication for underactive thyroid? is there any particular brand or supplement that is recommended? is anything particularly harmful?

Dee-lioness, have you had ferritin, vitamin D, B12 and folate tested? We need to know the results in order to advise whether supplementing is necessary or what doses to supplement.

The only supplements I recommend without testing are 1,000mg vitamin C, 375mg magnesium (citrate is better absorbed than oxide) and 15mg zinc.


Selenium too!


Petronella, thanks. Forgot about selenium :)
