Re: On Armour, doctor worried not getting T4
Your doctor has things mixed up a bit - T3 is created from the conversion of T4 - not the other way around.
However, her thoughts about adding some T4 in the form of Synthroid have merit.
You see, desiccated thyroid products are made from porcine thyroid that has a larger proportion of T3 than T4 compared to human thyroid. People taking desiccated thyroid will have FreeT3 levels that are proportionately higher in the range than their FreeT4 levels. Most people are fine with this.
People who aren't fine with this will most likely have a FreeT4 level that's below mid-range and ongoing hypo symptoms. That's when the addition of some T4 can help.
Please know that people who are optimally medicated on desiccated thyroid will have suppressed TSH (usually .02 or lower).
Since your most recent TSH is still higher than what a healthy person will have, that's a sign your FreeT4 and FreeT3 levels are too low for you....and, without a doubt, you needed a dose increase.
Your next labs will be very telling.
