Hello everyone. I am about to start 200 of selenium to see how i do. Currently on lots of vitamins and supplements plus synthroid. I am hoping this helps with conversion for me before i take the plunge of asking to try cytomel for T3. Has anyone seen proof of selenium working with that with your labs and if so, how long did it take & how much did you take daily. I love this site and the wonderful feed back i get. I learn more here than from my drs.
