It's January, which means it is national Thyroid Awareness Month. There is no better time to get acquainted with the important role that organically bound selenium plays in thyroid health for men and women. The thyroid needs adequate levels of selenium for antioxidant function and metabolism of thyroid hormones. In the past year, numerous studies showed that selenium supplementation reduced serum serum thyroid peroxidase (TPOAb levels).
Organically Bound Selenium and Thyroid Health
As new science has emerged, researchers are concluding that the form of selenium makes a significant difference in outcomes. If you haven't considered that the form of selenium makes a difference, take a look at the supporting data from 69 peer-reviewed publications, published in the International Journal of Endocronology (Jan. 2017). Here are the highlights, followed by a downloadable full text literature review.
- The organically bound selenium seems to be the preferable formulation for supplementation or treatment because it improves the immunological mechanisms of action that affect thyroid function.
- Selenium supplementation of patients with autoimmune thyroiditis is associated with a reduction in antithyroperoxidase antibody levels, improved thyroid ultrasound features, and improved quality of life.
- Selenium supplementation in Graves' orbitopathy is associated with an improvement of quality of life and eye involvement, as well as delayed progression of ocular disorders.
- Patients with thyroid cancer have lower serum selenium and magnesium levels and higher copper levels when compared with healthy controls. Although the specific mechanisms are not yet fully understood, the antioxidant properties of selenoenzymes may be relevant to risk and progression.
- Some trials show that there is a U-shaped relationship between selenium concentration in the blood and the risk of disease, with possible harm occurring both below and above the physiological range for optimal activity of some or all selenoproteins. Therefore, supplementation should be recommended to patients with low levels of selenium.
