Re: Iodine and selenium

Yes, a few important connections. The ratio selenium / Iodine is important. But, I believe there is another element coming up. Enzymes, relies on sulfur.

"Selenium is more in common with Sulfur because they are in the same group. They have the same number of valence electrons and the only elements Selenium is related to is Sulfur and Tellurium"

"Selenoproteins also act in various ways to change T4 into T3 (active thyroid hormone) and reverseT3 (which inactivates T3). Three main selenoproteins activate and inactivate thyroid hormone, known as D1, D2, and D3.

D1 is the primary activator of thyroid hormone for your body, working mostly in the liver and to some degree in the kidneys. D2 is active in the thyroid gland, brain, nerves, and heart. It plays the primary role in thyroid activation in the brain under normal conditions, and produces thyroid hormone for the rest of the body under stressed conditions. D3 is mostly a brake on thyroid hormone activity, turning off active hormone.

When your body starts to run low on selenium the activation of thyroid hormone by D1 may drop by 90%. Your body compensates by turning on the back up system, using the D2 enzyme to maintain active thyroid hormone. The problem with this back up system running for any great length of time is that is causes significantly increased production of free radicals. Even worse, the lack of selenium already handicapped the primary antioxidant that protects the thyroid gland and liver, GSH. Thus, selenium deficiency forces the body into a very uncomfortable metabolic coping strategy that eventually leads to slower metabolism, increased oxidative stress, and wear and tear to the thyroid gland and liver.*
