Re: How much T4 and T3 in Armour
Each grain (60 mgs) of Armour contains 38 mcgs of T4 and 9 mcgs of T3. T3 is 4 times more potent than T4, so the T3 within that one grain is as potent as 36 mcgs of T4. In the one grain of Armour, the 38 mcgs of actual T4 plus the T3 which is as potent as 36 mcgs of T4 is roughly equal in total to 74 - 100 mcgs of T4-only med.
Why do I say "roughly equal"? Because there are differences from patient to patient in the way the med is absorbed and converted from T4 to T3. In an ideal world, where the patient perfectly converts just the right amount of T4 to T3, and where the receptors on each cell completely absorb all the hormone available floating in the blood stream, it could be said that the 1 grain equals exactly 100 mcgs of T4. But the world isn't perfect, and the conversion/cell reception conditions rarely occur in absolute perfectionism. Almost everyone - women especially - have some degree of conversion and/or absorption difficulty. So it's more precise to say the 1 grain is equivalent to somewhere between 74 and 100.
Hope that didn't confuse you even more.
