I know my merc toxicity contributes to my fatigue and all the other crappola I have, however, I do know that through the stuff I have read that mercury can knock out your iodine in your body...so an supplement would help your body have a better chance at balancing itself while ditching the mercury, I would imagine.

That book I mentioned is a gold mine....check it out if you can...or Dr. Flechas website. www.helpmythyroid.com
