I found that Iodine was not enough for my "normal" thyroid blood results.
Almost immediately once I started on Nutrimeds Porcine thyroid glandular, my 4 yr insomnia disappeared, so I knew I was on to something.
I do take some magnascent and not every day, b/c my body still goes through hyper/hypo swings. Like yesterday, took some Iodine and almost immediately felt some effects with a racing heart.
In the end, I believe in iodine, glandulars and dessicated thyroid, but it has been many months of me trying to get the balancing act just right between the thyroid and adrenals.
