Research Overview
Calcitonin
Calcitonin has been evaluated in randomized trials and reviews for pain associated with vertebral compression fractures and other bone-related conditions. The signal is strongest for short-term analgesia rather than long-term chronic pain control.
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.
