Hilery, I was just told that selenium still helps with the conversion process even without a thyroid(mine's gone). I'm taking calcium and magnesium(ratio 2:1). Selenium 200mg(will switch to 100)when we finish tweaking my meds. You need a really good quality B-100 complex, Vitamin C, a little A, E. I take a small dose of potassium because I don't eat enough of the foods that have it. Also lysine,zinc and CoQ-10. I am also taking some other things to help my adrenals. I started all this about 6 weeks before and switched to Armour and I could tell it was helping as far as musle aches, tingling, etc. I am a horrible pill taker though(gagger), I wish I could just have a shot.
