The Claim

Children with congenital hypothyroidism receiving levothyroxine therapy exhibit significantly lower baseline concentrations of selenium, thyroglobulin, and T3, and significantly higher baseline concentrations of TSH, reverse T3, and T4 compared to euthyroid children without thyroid dysfunction.

Source: Selenium decreases thyroglobulin concentrations but does not affect the increased thyroxine-to-triiodothyronine ratio in children with congenital hypothyroidism.

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.

Description
1 study reviewed
In plain English

Children born with an underactive thyroid who take levothyroxine medication show different levels of certain thyroid-related substances in their blood compared to children with normal thyroid function, including lower selenium, T3, and thyroglobulin, and higher TSH, reverse T3, and T4.

See the scientific wording

Children with congenital hypothyroidism on levothyroxine therapy have lower baseline selenium, thyroglobulin, and T3 concentrations and higher TSH, reverse T3, and T4 concentrations compared to euthyroid controls, indicating a distinct biochemical profile in this population.

What the research says

1 study
  1. Study: Selenium decreases thyroglobulin concentrations but does not affect the increased thyroxine-to-triiodothyronine ratio in children with congenital hypothyroidism.

    Kids with congenital hypothyroidism on thyroid medicine have different blood levels of certain hormones and minerals compared to healthy kids — and this study found exactly that before giving them selenium supplements.
