Strong Support
People with autoimmune thyroid disease tend to have lower levels of selenium in their blood, whether their thyroid is underactive or overactive. This suggests the low selenium levels are linked to the autoimmune condition itself, not to whether the thyroid is producing too much or too little hormone.
