Re: What is the conversions
That exact information is on Armour's website, in the FAQs, I think.
They don't say it, but these aren't true equivalencies. They presume ideal conversion of T4 to T3, but we know that hardly anyone converts ideally.... There is nearly always some degree of conversion problem.
There's another site - which I can't post - that has a closer approximation which is more conservative. For example, Armour says 1 grain is equal to 100 mcgs levothyroxine, but in the real world (according to the other source), Armour can replace anywhere from 74-100 levoT.
