gdawson, do you know if DMSA or ALA will pull mercury out of the thyroid? My most troubling symptoms are mental/emotional and I want to be working on that with ALA. It would be quite some time before I decided to stop the ALA and just use DMSA along with high doses of iodine. If my thyroid is likely to be cleared over time anyway, chelating as I'm doing now, then the iodine can wait.
