A first-in-class oral peptide designed to keep intestinal tight junctions closed, studied as an adjunct therapy for celiac disease alongside a gluten-free diet. One of the more rigorously trialed gut-health peptides, with multiple completed phase 2 RCTs.

Gut health

KPV

Evidence labels

  • EmergingMostly preclinical or early signals; human athletic data is thin.
  • Limited human dataSome human pharmacology or small studies; outcomes for fitness use remain limited.
  • Stronger clinical signalSupported by larger clinical trials in defined medical populations.

Anodized by evidence strength: blue = stronger clinical/human data, violet = limited human data or mechanism, steel = emerging/anecdotal, and amber = an in-house STACKD summary.
