The Claim
Hydrogen peroxide produced during thyroid hormone synthesis is neutralized by glutathione, and this neutralization process requires selenium.
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.
During the production of thyroid hormones, hydrogen peroxide is generated and then removed by glutathione, a molecule that depends on selenium to function properly.
See the scientific wording
Hydrogen peroxide generated during thyroid hormone synthesis is neutralized by glutathione, a process dependent on selenium.
What the research says
2 studiesStudy: Serum Selenium Status in Autoimmune Thyroid Disorders: A Case-control Study
This study found that people with thyroid problems often have low selenium, and selenium helps the thyroid safely make hormones by cleaning up harmful byproducts like hydrogen peroxide. So low selenium may make thyroid damage more likely.
This study shows that adding selenium helps a special protein (glutathione peroxidase) clean up harmful hydrogen peroxide in human cells. Since thyroid glands make hydrogen peroxide when producing hormones, this supports the idea that selenium helps protect the thyroid by helping glutathione neutralize it.
