I am confused about NDT dosing. When I was on 1 grain of Thyroid-s (which is 38mcg T4 and 9mcg T3), my TSH levels went down to 0.01 and my T3 was 5.4 (reference range. 2.6-5.7)
I read that normal thyroid gland produces on average of 100 mcg T4 and 6 mcg T3 daily, although it secretes closer to 10 mcg T3 daily, because some T4 to T3 conversion occurs in the thyroid gland before release.
So this means even if TSH is only 0.01 which is almost undetectable, thyroid is still 50+% active. Is my conclusion correct or am I missing anything?
