a quick post - i've had some thyroid problems for the past 4 months and i learned if you have high reverse t3 you should not take anything with t4 in it. t4 creates rt3, which blocks your receptors for t3, the main thyroid hormone.

in order to clear your receptors of rt3 you need to take only t3, aka cytomel. http://www.thyroid-rt3.com/

after you clear your receptors you can think about going back on other thyroid medications. but until you stop taking anything containing t4 you're hypothyroidism will only get worse.

in order to do well on t3 only you need to have very good iron and stabilize your adrenals. both of these factors control the uptake of t3. there is a protocol to follow in which you monitor your adrenals and slowly build up your t3 medication until you clear, which is described on the website. it is a controlled and delicate process. i strongly suggest you read the whole t3 website and join the rt3 yahoo group. the moderators are very knowledgable and kind.

good luck!
