The Claim
Adjuvant selenium supplementation in patients with Graves' hyperthyroidism treated with antithyroid drugs is associated with faster restoration of biochemical euthyroidism, as evidenced by significantly lower free triiodothyronine and free thyroxine levels and higher thyroid-stimulating hormone levels at 6 months, though this effect is not sustained at 9 months and varies across studies with heterogeneous selenium compounds and dosages.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with Graves' disease taking antithyroid medications, adding selenium may lead to faster normalization of thyroid hormone levels at six months, but this effect does not last until nine months and differs depending on the type and amount of selenium used.

What the research says
1 studyStudy: Challenges and perspectives of selenium supplementation in Graves’ disease and orbitopathy
This study says taking selenium along with regular thyroid medicine might help normalize thyroid levels faster after 6 months, but the benefit doesn’t last long and works differently depending on the type and amount of selenium used.
