Background:
To assess the clinical benefits of Selenium (Se) supplementation in patients with Hashimoto thyroiditis (HT).
Methods:
Eight databases were searched for randomized controlled trials. The outcomes of interest were thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4). The study protocol is registered on INPLASY, DOI number is 10.37766/inplasy2022.10.0085.
Results:
Twenty-one studies with a total of 1610 subjects were included. Serum TPOAb was significantly reduced after Se supplementation after 3 months (standardized mean difference [SMD] = -0.46, 95% confidence interval [CI]: -0.74 to -0.18, P = .001) and 6 months (SMD = -0.80, 95%CI: -1.38 to -0.21, P = .008). The serum TgAb levels decreased at 3 months (SMD = -0.46, 95%CI: -0.79 to -0.12, P = .007) but not at 6 months. Significant effects on declining the TSH titers were found after 6 months (SMD = -0.18, 95%CI = -0.35 to -0.01; P = .03).
Conclusion:
Se supplementation help reduce TPOAb and TSH levels in HT patients, leading to improvements in well-being or mood. Selenomethionine is more effective than NaSe and Se-yeast in the teatment of Hashimoto thyroid.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
