After my question about meat and thyroid, we had an interesting connection.
The people at the web site below sent me their page on thyroid nutrients which is very well informed and you may find something of interest for yourself.
They wanted to link to our web page but since we have carefully guarded our impartiality the Board decided it was better not to do so.
The benefit would be advertising for them — because we have the means to check whether a person may need any of the supplements they suggest — the NST.
However, I can give you a heads-up here. Check it out.
