Yeah, it is interesting to read the comments after the article. Whenever Mercola puts in his personal comments, he has typos or misspellings. He clearly advocates the use of seaweed/kelp versus Lugol's and Iodoral (which he spelled wrong, lol) while at the same time recommending Brownstein's book.
Maybe he is selling kelp supplements or something, his site truly capitalizes on holistic health.
