It has taken 1 grain more of
Nature-
Throid (3 grains) to get similar results symptomaticly (no hypo.symptoms)
and similar blood levels, that we had on 2 grains of the "old" (before reformulation) Armour. My daughter takes 1 grain of Nature-throid every four hours (7:00am,11:00am, 3:000pm). It has been 5 months since switching to it (Nature-Throid) from the "new" (reformulated) Armour and she is now doing very well again! Yea!!!!
