You are clearly in a MUCH better position than most of us and if you are not exposed to halide toxins like most of us are, then you certainly don't need high doses of iodine for maintenance. We learned a lot from this file:
There is MAGIC going on between our brain and our body temperature. We don't need to know how or why. We don't need to know T3, T4 etc. What counts is the end result: Our body temperature. T3 & T4 measurements are affected by halogens.
This file says that if your "Basal Body Temperature" is a constant 98.6 degrees, then your thyroid is in good health, and therefore we can make some basic assumptions:
1) You are NOT hypothyroid, Not Hyperthyroid, and we don't need blood tests to tell us that.
2) Your thyroid is getting enough iodine
3) You do not need to add more iodine to your diet for your thyroid.
If our basal body temp drops below 98.6, then we need more iodine to repair our thyroid before it gets permanently damaged.
Our metabolism is determined by the thyroid, and iodine is required by the thyroid to do this.
Unfortunately, other organs in our body also require iodine. Female breasts, ovaries & uterus also require iodine. Prostate & Testes require iodine. After the thyroid, female breasts require more iodine than other organs. Do you have Fibrocystic Breasts? Then you need more iodine. If you have PCOS or Endo or cysts? then more iodine is the answer.
From what we know, a simple quiz should answer the question, Do we need more iodine?
1) Does your body basal temp get below 98.6?
2) Do you have Fibrocystic Breasts, Pcos, Cysts or Endo?
3) Do you have Prostate or testes problems?
If the answer is yes to any one of these questions, then more iodine is indicated.
So breadsauce, your low iodine may be the right choice for you, as long as you can answer the quiz. I have begun a new habit of checking my temp before getting out of bed. So far, so good. A solid 98.6 degrees on every test.
