The Claim

In women with autoimmune thyroiditis, thyroid autoantibody levels decrease during pregnancy and increase significantly in the postpartum period in the absence of selenium supplementation, suggesting that selenium supplementation may prevent this rebound.

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.

Cause and effect
1 study reviewed
In plain English

In women with autoimmune thyroiditis, levels of thyroid autoantibodies typically drop during pregnancy and rise again after childbirth unless selenium is taken, which may help prevent this increase.

See the scientific wording

Thyroid autoantibody levels naturally decline during pregnancy in women with autoimmune thyroiditis but rebound significantly in the postpartum period unless selenium supplementation is administered, indicating a window of opportunity for immunomodulatory intervention.

What the research says

1 study
  1. Study: Selenium supplementation in the management of thyroid autoimmunity during pregnancy: results of the “SERENA study”, a randomized, double-blind, placebo-controlled trial

    This study found that taking selenium supplements during pregnancy helps keep harmful thyroid antibodies low after giving birth, while women who didn’t take selenium saw their antibodies spike. So, selenium may help prevent thyroid problems after pregnancy.
