    OPtimal TSH for 95% of the populations is 0.89-1.1, basically as close to 1 as you can get. This is invalid if a person is on T3 supplementation or has pituitary dysfunction.

    OPtimal T3 and T4 levels are dependent on age and sex. A female of child bearing age has an optimal range of 50-80% of the normal range. My MFM and OBs prefer 60-80% if you are trying for a child. NOW if you are menopausal or post menopausal your level requirements drop. Optimal range shifts to 40-70% of normal. Where is your optimal? Well that depends on your needs. What is optimal? Well it is where in the optimal range your levels are balanced AND your symptoms are negligible.

    Can you give me numbers for the "normal ranges" of T3 and T4 ~ so then I can "do the Math"?

    Re: What is "normal"?

    You must get the ranges from the particular lab that runs your tests. There is no one standard for any of the tests/levels. The "normalcy" of your level depends entirely on where your result falls within your lab's range.
