Why the Free T3 test matters so much
It is surprising that Free T3 is considered an unnecessary test since it is the most active, most essential thyroid hormone in the human body. The research I outline in this post shows that Lower Free T3 levels in blood correlate with very poor health status both within and beyond “low T3 syndrome” — low…

The standard measure of thyroid gland health (the TSH normal range) is not a fair or accurate measure of thyroid hormone sufficiency in thyroid therapy. And the same meme, this time with MEN — since men have hypothyroidism too. In a 2015 article, Midgley et al (1) wrote “the effective TSH level derived in a…
