The Claim
In patients with subclinical Hashimoto’s thyroiditis not on levothyroxine, six months of 200 μg/day selenium yeast supplementation is associated with a significant reduction in thyroid-stimulating hormone (TSH) levels by an average of 0.16 mIU/L, while untreated controls show an increase of 0.48 mIU/L.
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.
In people with early-stage Hashimoto’s thyroiditis who are not taking thyroid medication, taking 200 micrograms of selenium yeast daily for six months is linked to a small decrease in TSH hormone levels, whereas those not taking selenium experience a small increase.
See the scientific wording
In patients with subclinical Hashimoto’s thyroiditis not on levothyroxine, six months of 200 μg/day selenium yeast supplementation is associated with a significant reduction in thyroid-stimulating hormone (TSH) levels by an average of 0.16 mIU/L, while untreated controls show an increase of 0.48 mIU/L, suggesting selenium may improve thyroid function in early-stage disease.
What the research says
1 studyThis study found that taking selenium supplements for six months helped lower a key thyroid hormone (TSH) in people with early-stage Hashimoto’s, while those who didn’t take it got worse. So selenium may help the thyroid work better in the early stages.
