Quick Summary

In this meta-analysis, selenium supplementation improved levels of thyroid-stimulating hormone and thyroid peroxidase antibodies in participants with Hashimoto’s thyroiditis.

What was studied?

The effect of supplementation with selenium on outcomes related to Hashimoto’s disease.

The primary outcome was thyroid-stimulating hormone (TSH) levels in participants who were not on thyroid hormone replacement therapy (THRT; THRT affects TSH levels), though analyses were also performed in participants who were on THRT and in participants overall.

The secondary outcomes were total and free T4, total and free T3, thyroid antibodies (thyroid peroxidase antibodies, thyroglobulin antibodies, and thyrotropin receptor antibodies), thyroid ultrasound findings (opaqueness and thyroid volume), immune and oxidative biomarkers (e.g., malondialdehyde), participant-reported outcomes, and adverse events.
