Doctors today are taught that “the” thyroid secretes T4 and T3 at a ratio of 14:1, or 15:1, and “the” human body converts 80% of its T3 supply from T4. These ratios are now taught and passed on as if they are static, immutable laws of nature, like the law of gravity. However, studies of complex … Continue reading Question Pilo’s study: The wide range of thyroid hormone adaptation
This post continues my series that examines two ratios T4:T3 thyroid hormone secreted by “the” thyroid gland. The single origin of both these ratios is an article by Pilo et al published in 1990. A simple summary: In Pilo's' study, the huge doses of iodine these 14 people were given every day during the … Continue reading Question Pilo’s study: Iodine dosing biases T4:T3 secretion
In this series, I am examining two T4-T3 thyroid hormone ratios that have been circulating in thyroid medical literature for decades. The first ratio is the “molar ratio” of T4 and T3 hormone secretion from the thyroid gland. The second ratio is the theory that the human body derives 20% of its T3 hormone supply from … Continue reading Question Pilo’s 1990 study. It can be misused to limit your T3 supply.
Here are the two most pervasive, limiting, and potentially harmful presumptions about T3:T4 hormone ratios in thyroid science today. Ratio #1: There is a perfect physiological T4:T3 ratio secreted from the healthy human thyroid gland, and it is approximately 15:1. (Various ratios are cited, most often from 13:1 to 16:1) Ratio #2: In the … Continue reading The two T4-T3 ratios that confine thyroid therapy
