Have you seen the other cautiionary thread on Vitamin D?
I read Kierkergard's thread.
Was told today my Tsh is about 0.42, range 0.4-4.2 and target value 0.5-1 so its pretty much spot on where i want it.
Free t3 was not checked, still waiting for result on free T4.
Considering to lower levothyroxine from 100->75mcg and increase triiodthyronine 10->20mcg.
