How to Make & Metabolize T4 Thyroid Hormones

what is the chemical makeup of the the critical thyroid hormone known as T4? very simple, it is covalently bonded Iodine and tyrosine.

whats fascinating is that kelp already has Iodine bonded to tyrosine! that means it has T4 precursors, and is the perfect food for thyroid health.

now, if you have abandoned kelp and are taking pure iodine, you may want to consider supplementing with tyrosine to give your body the basic building blocks of T4. almonds, dairy products, pumpkin seed, and sesame seeds are all high in tyrosine.

however, if you make T4 but lack two other nutrients you will not be able to convert T4 into the biologically active T3. T3 is the active form of T4, meaning that its only in the T3 configuration that your cells can utilize T4.

the critical elements you need to convert T4 to T3 are protease and selenium. protease metabolizes the T4. during this process one molecule of Iodine is displaced by one molecule of selenium. thus if you are selenium deficient, you cannot convert the T4 into T3. brazil nuts, most meat products, and rice are all high in selenium.

the above was mostly gleaned from these two sites.
