The Claim

In patients with newly diagnosed Graves' disease and low baseline selenium and vitamin D levels, supplementation with 100 mcg/day selenium and 7000 IU/week vitamin D for six months significantly improves patient-reported quality of life as measured by the ThyPRO composite score, with the greatest benefits observed in cognition and social life domains, independent of thyroid hormone normalization.

Cause and effect
1 study reviewed
In plain English

In patients newly diagnosed with Graves' disease who have low selenium and vitamin D levels, taking 100 micrograms of selenium daily and 7000 international units of vitamin D weekly for six months leads to a measurable improvement in quality of life scores, particularly in cognitive function and social well-being, regardless of changes in thyroid hormone levels.

See the scientific wording

In patients with newly diagnosed Graves' disease and low baseline selenium and vitamin D levels, supplementation with 100 mcg/day selenium and 7000 IU/week vitamin D for six months significantly improves patient-reported quality of life, as measured by the ThyPRO composite score, with the greatest benefits observed in cognition and social life domains, independent of thyroid hormone normalization.

Why this might work

Selenium and vitamin D work together to calm the immune attack on the thyroid and reduce harmful chemical stress in the body. This allows the thyroid to return to normal function faster, which reduces the overload of stress signals to the brain. With less inflammation and chemical imbalance, the brain works better, especially in areas that control thinking and social behavior, leading to clearer thoughts and improved social comfort.

  1. Study: Add-On Effect of Selenium and Vitamin D Combined Supplementation in Early Control of Graves’ Disease Hyperthyroidism During Methimazole Treatment

    People with Graves' disease who were low in selenium and vitamin D felt better mentally and socially after taking these supplements, even after their thyroid hormones stabilized — and they felt better more than those who only took their regular thyroid medicine.
