I have a friend on another health group who commented on the Video and has seen it before. She says she did not get the official dx until 60, but a lot of symptoms for many years. She's avoided a lot of drugs and does a lot of supplements including LDN but mentioned the importance of T3. I know many who take synthroid T4 do not convert well to the T3, so I've heard. I personally take desiccated thyroid which has both T4 and T3 and other ingredients. I don't know what my sister took with any thyroid support.

My friend claims out of the FIGHT list her issues are more infections and hormones.

Here's a link she presented on the T3 and MS:
