Susan has Hashimoto's thyroiditis, an autoimmune thyroid disorder causing fatigue, puffy face and muscle weakness. For the past year, she had been under the care of other doctors who started thyroid medication (Synthroid), and tested her thyroid antibody levels. The disturbing thing was that her antibodies kept climbing higher on each follow up lab test. The doctors had no explanation, so she asked me if there was something else that could be done.
Selenium Can Decrease Antibody Levels
As it turns out, there is a trace mineral called selenium that plays an important role in thyroid biochemistry. Selenium deficiency has been implicated in the etiology of Hashimoto's thyroiditis, and selenium supplementation has been found beneficial.
