Have a look at this.. the glandulars is the only thing so far your doc has said, that has some substance IMO;
"Dr. Starr is the author of “Hypothyroidism-Type 2.” He said synthetic thyroid acts energetically differently in the body. “All living things have a right spin, and synthetic medications have a left spin. The desiccated thyroid is better tolerated.”
Dr. Broda Barnes did a study that revealed a relative intolerance to a synthetic thyroid product containing T3 and T4 (Thyrolar). One-fifth of the patients who had done well on desiccated thyroid developed rapid heart beats and palpitations when switched to Thyrolar. Dr. Barnes also did a major research study on desiccated thyroid that involved thousands of patients over 30 years; it showed a 94 percent reduction in the number of expected heart attacks. This study is the subject of the 1976 book “Solved: The Riddle of Heart Attacks.”
