A naturopathic/holistic doctor would be more likely to be willing to treat you by symptoms rather than by TSH levels, since TSH is pituitary
hormone, not a thyroid
hormone...
Just as important as TSH and Free T4 is the Free T3 thyroid hormone. Free T3 is the active hormone, used by individual cells, whereas Free T4 is considered a "pro-hormone" and must be converted to the active Free T3. You may have a conversion issue, or an absorption issue.
