In people with Hashimoto's thyroiditis, lower levels of selenium in the blood are linked to higher levels of antibodies that attack the thyroid gland, even when overall selenium levels are not deficient compared to healthy individuals.

Plasma levels of Th17‐associated cytokines and selenium status in autoimmune thyroid diseases

Cross-Sectional Study

Human

2021 Sep

This study found that people with Hashimoto's who have lower selenium in their blood tend to have higher levels of antibodies attacking their thyroid, even if their selenium isn't dangerously low. So, having just a little less selenium might make the autoimmune attack worse.
