underactive thyroid
"I can't believe how much better I felt immediately after starting this (25 mcg). I resisted taking it for a year. I was afraid of side effects and wasn't convinced that my thyroid was the problem. My TSH was only slightly high (average 6; high 11). I was so used to feeling lousy that whenever the doc asked about my energy, I said it was fine. I thought I was just aging fast (I'm 38). I'm not overweight, I've been athletic most of my life but have dragged during exercise for the past 2 yrs. I've also suffered from persistent depression and anxiety. I took antidepressants for a while but never felt great. I feel so good now. My physical stamina and motivation are back, I wake with energy. Very happy."
