How specifically does low ferritin affect the thyroid ?
All articles say it effects the active t3 binding, but they do not explain does this mean t-3 actually doing its job at the receptor or the conversion of t4 to t3.
There is speculation that with low ferritin that thyroid can not be activated at the tissue level. Is this really true because I thought cortisol was responsible for this function. Reason being is that I have ferritin of 40 and my hair keeps falling out. I have had low ceruloplasm and copper serum for 5 years now but no one can give me an explanation to why this is. I even supplemented thinking I was low 5 mgs a day reducing zinc down to 30 mgs a day and retested in 2 months. While taking the supplement up to night before the test it still tested low. How can this be..With out ceruloplasm iron does not get transported to the tissue as indicated on alot of my functional test as well as hair analysis copper, iron, molybednum were all low and have been for years. I;m just confused. I have alot of signs of wilsons disease but can not get an accurate diagnosis. I do take iodoral and I have heard this can deplete iron levels but even taking 50 mgs a day I test ferritin at 42 even taking iron night before the test. When was my healthiest ferritin was 166. Could the copper transport defect be causing low ferttin despite proper supplementation? I do have low thyroid which I am working on to get numbers in optimal range. My last numbers where good but the lab did not test the total levels so they basically where useless for me. From my research and healthy people (no thyroi/adrenal issues) I tested who do not take iron supplementations ferritine levels range from 130-200.
