A few articles for the ones that like the long read.
"according to Dr. David Derry from Canada, there are active thyroid hormone sites in all the mitochondria, and when there is enough Iodine
to activate the thyroid, we increase ATP production in all cells as well. This is important because cancer cells have 200-300 mitochondria per cell, whereas healthy cells have 3,000-5,000 mitochondria per cell, yielding significantly more energy and protection from cancer." - See more at: http://treeoflifecenterus.com/blog-posts-by-gabriel-cousens-m-d-iodine-96-the-universal-holistic-super-mineral-2/#sthash.e3B12pMQ.dpuf
"Magnesium deficiency has been shown to lead to fewer mitochondria in cells(5), so getting sufficient levels of magnesium is important to generating many mitochondria. Iodine
is another important nutrient to make sure you are getting enough of to support healthy mitochondria. In addition to it's role as a component of thyroid hormone which regulates metabolism throughout the body, Iodine
also has an important role to play in cell apoptosis(6) which it apparently mediates through mitochondrial mechanisms(7, 8). In one study, iodine was shown to induce apoptosis in human Breast Cancer
cells but not in healthy cells that surround the cancerous cells(7). In another, iodine helped induce apoptosis in 4 out of 5 Breast Cancer
