The Claim

Pregnant women taking 83 mcg/day of L-selenomethionine exhibit significantly higher serum selenium concentrations compared to those receiving placebo, with elevated levels persisting at six months postpartum, demonstrating effective absorption and sustained bioavailability of L-selenomethionine.

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

In plain English

When pregnant women take a daily supplement of 83 micrograms of L-selenomethionine, their blood selenium levels rise significantly and remain higher than those of women taking a placebo, even six months after giving birth.

See the scientific wording

Serum selenium concentrations increase significantly in pregnant women taking 83 mcg/day of L-selenomethionine compared to placebo, with levels remaining elevated at six months postpartum, indicating effective absorption and sustained bioavailability of this form of selenium.

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

    Pregnant women who took a specific selenium supplement (L-selenomethionine) had much higher selenium levels in their blood during pregnancy and still had high levels six months after giving birth, meaning their bodies absorbed it well and kept it for a long time.
