Quitting supplements for Hashimoto test?

Question by Bregje: I am considering the Hashimoto test. I take supplements daily. Do you recommend temporarily stopping these then? If so, how far in advance?

A: Supplements and even thyroid medications do not affect the antibodies to the thyroid that we measure with the Hashimoto test.
If you measure vitamins and you take those vitamins, we measure what the level is in your blood, with this supplementation.
