Research Overview

Omentin-1

Lower omentin-1 levels are often associated with obesity, insulin resistance, and metabolic syndrome. Research continues on its use as a biomarker and as a mechanistic lead for AMPK-linked metabolic interventions.

Larazotide

Clinical and translational studies suggest larazotide can reduce antigen passage across the epithelium and improve gut barrier function. It is one of the better-known peptides for intestinal permeability and barrier-focused gastrointestinal therapy.
