Another aspect to consider once the hormone is converted is if it can hitch a ride to the target cell and get there on time. The cell is the like the store at the mall and inflammation would be equilievent to traffic. God forbid you can’t even spend the money you have because no one will drive you to the mall or you get stuck in traffic! Now let’s imagine you make it to the mall but the cash register is not working. This would be similar to the cell not working properly despite you having your cash in hand. Since your payroll department (TSH and thyroid) kept up their end of the deal they are off the hook. These issues are known as peripheral conversion problems that are not part of your thyroid treatment since they are extraneous to the thyroid gland. This is why millions of women get “normal” lab reports and still feel like “crap”.

Since most doctors only check for T4 (and assume the bank is open, ie your liver, kidney, and gut bacteria are doing their job and your zinc and selenium levels are normal), your T3 gets overlooked and you are told that everything is “normal”. Despite the fact that your energy is still low, metabolism is sluggish, and weight is not budging on the scale, you are given the green light.
