If you have taken LDN and you have / used to have Hashimoto's (high thyroid antibodies), please click on all choices that apply to you. I'm a tad confused about which questions I should ask to get the information I want. So please give details in the comments if you have something to add. I can't vote yet because my ND has just prescribed LDN for me. I talked to a pharmacist at Skip's, who told me that LDN addresses the actual cause of the autoimmune thyroid disease, instead of just throwing thyroid hormone at it.
