my post about arsenic, more arsenic; was to indicate that the kelp/seaweed route instead of iodine; may not be the best choice; and why.
Second; to show that the antagonist to arsenic actually are Iodine and selenium, possibly vit C. All parts of the co-supplements we tend to recommend at this forum.
I believe it would me more fruitful to follow this up, instead of picking on one sentence from a link I posted.
