This is what I was told about the reformulations about Armour Thyroid.
It was reformulated once in 2008 and remains the same.
It is doubtful there are any old formulations on the market at this time.
The dextrose was removed at that time.
There is a slight increase of filler in the larger tablets because of the size of the pill but the active ingredient is equal to the dose of the pill.
I am waiting to see if there are any irregularities with a certain batch that I had questioned filled in February.
