The Claim
Daily supplementation with 200 μg of selenium for 12 months has no effect on quality of life in adults with hypothyroidism due to autoimmune thyroiditis who are on stable levothyroxine therapy, as measured by the ThyPRO-39 composite score, despite a statistically significant reduction in thyroid peroxidase antibody levels.
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.
Taking 200 micrograms of selenium daily for a year does not improve how people with autoimmune hypothyroidism feel on a standardized quality-of-life survey, even though their thyroid antibody levels decrease.
See the scientific wording
Daily supplementation with 200 μg of selenium for 12 months does not improve quality of life in adults with hypothyroidism due to autoimmune thyroiditis who are on stable levothyroxine therapy, as measured by the ThyPRO-39 composite score, despite a statistically significant reduction in thyroid peroxidase antibody levels.
What the research says
1 studyTaking selenium pills for a year didn’t make people with hypothyroidism feel better in their daily lives, even though it lowered some antibody levels. So, the selenium didn’t improve how they felt.
