5 years they realized I do not convert T4 (
Synthroid)
to T3, so even though my T4 came out fine, my T3 was
to low and is causing my symptoms, why no one could catch this before, I don't know. Now I have to decide wether to take Armour (Has both 3&4) or take a supplement with the Synthroid, I just posted that question for opinions but no response yet. So just post when you get it together, I will sign it, because it is rare to find regular MD's that will prescribe Armour.
