- Low evidence4 studies
Across 4 studies, 2 reported beneficial effects of selenium supplementation on reducing thyroglobulin antibody (TgAb) levels, while 2 reported neutral effects; effect sizes were predominantly small to moderate. The evidence is mixed, with one meta-analysis showing a moderate beneficial effect at 3 months but not at 6 months, and another large meta-analysis finding no significant change. Most studies focused on patients with Hashimoto thyroiditis (clinical population), and the median study duration was 182 days (6 months) in the single study reporting duration, though effects were observed at 3 months in one analysis.
