Research Overview

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.

Insulin Aspart

Research consistently shows faster onset and earlier peak action than regular human insulin. It is commonly studied for meal-time glycemic control and pump-based insulin delivery.
