Selenium and Graves’ Disease

Graves’ disease is an autoimmune disease. It is the most common cause of hyperthyroidism, i.e., overactive thyroid disorder. Ultimately, it is the overproduction of thyrotropin receptor (TRAb) antibodies that results in hyperthyroidism. Over time, Graves’ disease causes extensive damage to thyroid gland cells and tissues [Song 2023].

Oxidative stress appears to play an important role in Graves’ hyperthyroidism. Oxidative stress is the medical term for a disruption of the balance between harmful free radical oxidants and protective antioxidants. The increased production of reactive oxygen
radicals and inflammatory cytokines drives the development and progression of Graves’ disease [Song 2023]. read more

Selenium and Vitamin D for Thyroid Health

Supplementation with selenium and vitamin D can improve the prognosis of type 2 diabetes mellitus and Hashimoto’s thyroiditis. Adding a daily dose of selenium and vitamin D to conventional diabetes medication can give significant health benefits [Yu 2024].

Selenium and Vitamin D for Type 2 Diabetes and Thyroid Disorder
A Chinese study suggests that combining conventional diabetes medicine with selenium and vitamin D supplements  reduces the levels of TSH and TPOAb and blood glucose and blood lipids in patients with concomitant type 2 diabetes and Hashimoto’s thyroiditis.

Researchers at Hunan University of Chinese Medicine, Hunan Province, China, recommend 100-200 mcg/day of selenium and 100 mcg/day of vitamin D for three to six months for patients with Hashimoto’s thyroiditis and especially for Hashimoto’s thyroiditis patients with concomitant type 2 diabetes [Yu 2024].

A 2024 study by Feng et al has shown that adding 200 mcg of selenium daily and 100 mcg of vitamin D to standard anti-diabetic drugs significantly improved thyroid function, thyroid antibodies, blood glucose, and blood lipids in type 2 diabetes patients who were also diagnosed with Hashimoto’s thyroiditis. read more
