The Claim
In adults with Hashimoto's thyroiditis who are not selenium deficient, selenium supplementation is associated with a 33% higher relative risk of developing any new autoimmune disorder and a 61% higher relative risk of developing Sjögren's syndrome over a five-year period, indicating potential systemic immune dysregulation.
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.
Among adults with Hashimoto's thyroiditis who have normal selenium levels, taking selenium supplements has been linked to a higher chance of developing other autoimmune conditions, including Sjögren's syndrome, over five years.
See the scientific wording
Among adults with Hashimoto's thyroiditis not deficient in selenium, supplementation is associated with a 33% higher relative risk of developing any new autoimmune disorder and a 61% higher relative risk of developing Sjögren's syndrome over five years, suggesting a potential systemic immune dysregulation triggered by selenium.
What the research says
1 studyThis study found that giving selenium supplements to people with Hashimoto's thyroiditis—even if they weren't deficient in selenium—made them more likely to develop other autoimmune diseases like Sjögren's syndrome. So, the supplements might be doing more harm than good.
