TSH - Anything from 1-4 is considered normal. Some will argue anything over a 3 is abnormal.

I assume you are taking Synthroid/Levothyroxine.
Long term use of these meds lead to osteoporosis. In which you should be taking a calcium supplement for. But do not take the supplement at the same time as taking your thyroid meds.
I would not be concerned about being hypo (your levels are great)unless you are still displaying signs of being hypo. Most commonly insomnia, hair loss, joint & muscle pain, inability to lose weight, bloating, brain fog and fatigue.
If that is the case it may be advisable to inform your Dr. but be forewarned most Drs say phooey and wont do a thing. More people have success with going on ARMOUR.Take care.
