1.Iodine: The body needs iodine to make thyroid hormone. The WHO estimated in 2007, that over 30% of the world’s population (which amounts to 2 billion people) has insufficient iodine intake as measured by urinary iodine excretion below 100 micrograms (mcg)/liter. To prevent this deficiency one can add iodized salt in your daily diet, which can be an effective preventative measure. 2.Selenium: After iodine, selenium is probably the next most important mineral affecting a person’s thyroid function. The thyroid contains more selenium by weight than any other organ in the body. Without this potent mineral, there would be no activation of the thyroid hormone as it is a necessary component of the enzymes that remove iodine molecules from T4 converting it into T3. Whilst testing selenium levels of patients with thyroid disease, it was found all of them had lower levels than normal healthy individuals. Some researchers suggest that selenium supplementation will improve conversion of T4 to T3. The cells of the thyroid generate hydrogen peroxide and use it to make thyroid hormone. Selenium has the function of protecting the thyroid gland from the oxidative damage caused by these reactions. Without adequate selenium, high iodine levels lead to a destruction of the thyroid gland cells. 3.Additional nutraceuticals which can be taken are: Zinc: Copper, Curcumin (as highly absorbed BCM-95), Natural Vitamin E, Vitamin C, Iron, Vitamin B12, DHEA, Pregnenolone, Rhodiola, L-tyrosine
