Taken what? Please be exact. Natural or synthetic?
Doesn’t matter. Low thyroid is incredibly common, especially in women and most especially in older women.
Whether taking basic T-4 Synthroid type or the natural, which combines T-3 and T-4 (closer to what the body uses) doesn’t matter.
This is a total nothingburger.
Most of my female family members are on Armor. The synthetic crap does not work for them.
