The Claim

In young women with Hashimoto's thyroiditis, fluctuations in thyroid peroxidase and thyroglobulin antibody levels are correlated with concurrent fluctuations in 25-hydroxyvitamin D levels following vitamin D supplementation.

In plain English

In young women with Hashimoto's thyroiditis, changes in vitamin D levels after supplementation are associated with changes in thyroid antibody levels.

See the scientific wording

In young women with Hashimoto’s thyroiditis, changes in thyroid peroxidase and thyroglobulin antibody levels correlate with changes in 25-hydroxyvitamin D levels following supplementation, indicating a potential link between vitamin D status and autoimmune activity.

Why this might work

When vitamin D levels rise, immune cells that calm down overactive responses become more active, while immune cells that attack the thyroid become less active, leading to lower levels of antibodies targeting the thyroid.

  1. Study: Gluten-free diet attenuates the impact of exogenous vitamin D on thyroid autoimmunity in young women with autoimmune thyroiditis: a pilot study

    When women with Hashimoto’s took vitamin D supplements, their antibody levels went down — and the more their vitamin D levels rose, the more their antibodies dropped. This suggests vitamin D might help calm the immune system’s attack on the thyroid.
