If you do not have enough iodine to make your hormone with, that could give confusing test results. You could try 2 a day.
I use this because I don't use iodized salt, and I had a goiter at one time.

This is the one I use.

There is a group of people who use very HIGH iodine and I am unsure whether this is safe. So I don't endorse it.

You could ask your new naturapath for comments.
Iodine is supposed to be conserved in the body by the kidneys, but it is conceivable that that process can fail for some reason, and thus the person loses the iodine.

Here is an eMedicine article on Iodine:
