The Claim

Patients with Hashimoto thyroiditis have significantly higher serum zonulin concentrations compared to healthy controls.

Supports is higher

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

In plain English

People with Hashimoto thyroiditis have higher levels of zonulin in their blood than people without the condition.

See the scientific wording

Patients with Hashimoto thyroiditis exhibit significantly higher serum zonulin concentrations than healthy controls, indicating increased intestinal permeability, or 'leaky gut,' in this population.

Why this might work

An imbalance in gut bacteria causes the gut lining to release a protein that opens the seals between intestinal cells, allowing substances to leak into the bloodstream.

  1. Study: Detection of Alterations in the Gut Microbiota and Intestinal Permeability in Patients With Hashimoto Thyroiditis

    People with Hashimoto's thyroiditis had higher levels of a protein called zonulin in their blood, which means their gut lining might be more 'leaky' than in healthy people. This suggests their intestines may be letting things pass through that they normally shouldn't.
