Larazotide zonulin antagonist research, anyone here actually tried it for gut permeability

Just came across the larazotide acetate stuff on the /peptides/larazotide page and honestly this is the first tight junction regulator ive seen that actually has a plausible mechanism. It blocks zonulin from pulling apart the proteins that hold your gut lining together, which is pretty different from the usual "take glutamine and collagen" approach you see everywhere.

For what it is worth, gut issues are a massive thing in ultrarunning. Hours of reduced blood flow to the gut, repeated mechanical jostling, and you end up with absorption problems and nausea that can wreck a race. Ive dealt with that personally and the standard advice of just eating more gels or switching fuel sources never fully sorted it for me.

What catches my eye is that larazotide was developed for coeliac disease and has actual clinical backing for reducing intestinal permeability. That is heaps more than most gut peptides can claim. The dosing of 0.5 to 1mg three times daily before meals seems reasonable too, not some wild extrapolation.

My question is whether anyone here has run it for non-coeliac gut issues, like exercise-induced permeability or general inflammation. Did you notice anything concrete or was it subtle. Keen to hear real experiences before i dig deeper into the literature.
