The Claim

Supplementation with 83 mcg/day of L-selenomethionine during pregnancy and for six months postpartum significantly reduces thyroglobulin and thyroid peroxidase autoantibody titers in women with autoimmune thyroiditis compared to placebo, indicating a modulatory effect on thyroid autoimmunity during the postpartum immune rebound phase.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect

In plain English

Taking 83 micrograms of L-selenomethionine daily during pregnancy and for six months after childbirth is associated with lower levels of specific antibodies targeting the thyroid in women with autoimmune thyroiditis, compared to those taking a placebo.

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 a specific selenium supplement during and after pregnancy helped lower harmful antibodies in women with thyroid problems, while those who took a dummy pill saw their antibodies go up. So yes, the supplement seems to help calm the immune system’s attack on the thyroid after birth.
