Larazotide vs Vesugen
An educational, source-based comparison of Larazotide and Vesugen — how each peptide works, what it's researched for, and what to know before going deeper.
An octapeptide zonulin antagonist that helps maintain intestinal tight junction integrity, reducing paracellular permeability triggered by gluten in celiac disease.
- Celiac disease (Phase 3 completed)
- Intestinal barrier function ('leaky gut' research)
- Environmental enteropathy
- • Not yet FDA-approved.
- • Investigational; physician oversight required.
A synthetic tripeptide (Lys-Glu-Asp) in the Khavinson bioregulator family. Research indicates modulation of endothelial cell function and vascular wall gene expression, supporting vascular tone and microcirculation.
- Vascular endothelial function
- Microcirculation in aging
- Peripheral vascular disorders
- • Russian-origin research; independent replication limited.
- • Not FDA-approved.
Trial-evidence rating
