Iodine/Potassium Iodide

In 1829, a French physician, Dr. J.G.A. Lugol, developed a liquid form of iodine called Lugol’s Solution. This combined the elemental iodine with an iodine salt in the form of potassium iodide. One of its many applications was in the treatment of hypothyroidism in the latter part of the 19th century. 

Early studies as far back as 1923 demonstrated reversal of goiters in adolescent girls with 9 mg of iodine. However, Lugol’s solution was tedious to work with. It fell out of favor and became largely forgotten once the Armour company developed porcine glandular thyroid 100 years ago.

In the last 10 years, the science behind iodine and the body’s uses of iodine has exploded. Doctors are still being taught in medical school that the thyroid gland was the only location in human physiology that iodine was used. That is now been proven incorrect.

We now know that the thyroid and breast tissues are the chief consumers of iodine and other areas are equally important, including the salivary glands, brain, stomach, ovaries and your eyes. Women require much more iodine than men because breast tissue uses so much iodine. Perhaps this is the reason why women seem to have so many more problems with hypothyroidism than men?


Selenium is necessary for proper functioning of the enzyme, iodothyronine deiodinase. This is the enzyme that is critical for conversion of T4 into T3 (the active thyroid hormone).

Selenium is recommended to enhance the conversion of T4 into T3. With supplementation of selenium, you can achieve higher levels of active thyroid hormone.

The maximum daily dose of selenium should not exceed 400 mg/day.

Vitamin B2 (Riboflavin)

Riboflavin is a major cofactor in the energy production pathway of ATP, called oxidative phophorylation. Inside the thyroid cells are energy producing components called mitochondria. Tired, worn out thyroid glands are unable to produce enough energy. 

The addition of Vitamins B2 enhances your mitochondria to produce sufficient energy to power your thyroid gland to properly metabolize iodine into the correct chemical form.

It has been shown that Vitamin B2 can exert a synergistic effect in conjunction with the iodine to kick start your thyroid gland into making proper amounts of active thyroid hormones.
