The Claim

In adults with Hashimoto’s thyroiditis, six months of selenium supplementation increases the proportion of activated regulatory T cells and enhances Helios expression on these cells.

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.

How it works
1 study reviewed
In plain English

In people with Hashimoto’s thyroiditis, taking selenium supplements for six months is associated with an increase in a specific type of immune cell called activated regulatory T cells, as well as higher levels of a protein called Helios on those cells.

See the scientific wording

In adults with Hashimoto’s thyroiditis, six months of selenium supplementation increases the proportion of activated regulatory T cells (aTregs) and enhances Helios expression on these cells, suggesting a potential immunomodulatory mechanism through T-cell regulation.

What the research says

1 study

  1. Study: Effect of selenium on thyroid autoimmunity and regulatory T cells in patients with Hashimoto’s thyroiditis: A prospective randomized‐controlled trial

    This study found that taking selenium supplements for six months helped increase special immune cells called aTregs and made them more active by boosting a protein called Helios, which may help calm down the immune system in people with Hashimoto’s.
