Since I've supplemented with Vitamin D my TSH level has come down from 5.12 to 1.6.
I posted incase others have found this too or maybe it is just me. (PT, not on Levo or other medication, just the occasional multivit, brazil nut & magnesium spray). Although I feel much better painwise than this time last year, I'm still cold, tired and brainfoggy etc. Jane
