Reply To: I am in my 6th week of taking 10,000iu for vitamin D deficiency. My level was 28ng/ml. I have symptoms of depression and muscle weakness. How long of supplementing until I feel relieved of my symptoms?
Sorry but most doctors only do one test for hypothyroidism and that is the TSH test. They call it the “gold standard” for detecting hypothyroidism. Unfortunately the blood level range for it is wrong. It usually goes from 0.4 – 4.5. and there is MUCH evidence that it should be lowered to 0.4 – 2.5. Hashimoto’s disease sometimes only shows on the antibody testing I listed above, meanwhile your TSH test is so called normal. Even the FT4 and FT3 ranges are “badly” scewed.
