My TSH was 1.4 to 1.6 without thyroid issues (TSH rose above this range with Hashimoto's thyroiditis). I assumed 1.4 to 1.6 was healthy. But I did not consider my health...I am not a healthy person. I had insulin resistance for decades for a start not to mention numerous other health issues. So this article was very interesting...
"To start with I have never seen a healthy individual with a TSH > 1.0.
This would indicate, at least subjectively, that the ideal TSH (provided disease is not present in any form) is somewhere around 1.0.
Nowadays due to the Standard American Diet, decreased activity levels, absurd rates of insulin resistance and many other factors it is truly rare to see a "healthy" person.
Standard american diet
That means we need to change our definition of "normal"."
"Bottom line: The "Optimal" range for TSH should be < 2.0, anything higher indicates potential hypothyroidism. Do NOT use the standard lab reference range as your definition of "optimal"."

Your TSH is within the normal range, but TSH is only one test. Is it the only thyroid related blood test that was done? What about Free T4 and Free T3? Those are the actual thyroid hormones and are much more important than TSH. What, if any, thyroid related symptoms do you have?
What other blood work was "out of whack"?
