I just received results of my urine iodine test. My levels are almost double what they should be. I have high cortisol and have been taking Seriphos to bring it down. Because it is methylated, I've been taking 250 mgs no-flush niacin with it three times per day. I've read a couple of short articles that mention niacin can stop methylation which can cause excess iodine. Has anyone experienced or heard of this?
