Yes I take all the companion nutrients. I have fibromyalgia now and had chronic fatigue syndrome in my 20's (I'm 40 now). My muscles have been in constant pain for 25 years. I have had health problems since I was 7 years old (I blame the cat allergy shots I had twice a week for a whole year which were subsequently banned). I never did find out why those shots were banned. I wonder what they were pumping into my arm? Doctor's don't care about my pains and want to put me on antidepressants, which I not so politely decline. I definitely have signs of Hypo, even the more unusual ones such a yellow toned skin. If you are Hypo then apparently you cannot break down beta carotene effectively, or something like that.
Anyway, I had lots of bloodwork done but not the in-depth thyroid ones so that is my next step. Hopefully I won't have to beg. I live in the UK so if you get free health care they tend to tell you what you can or cannot be tested for.
