Larazotide
A synthetic peptide that regulates intestinal tight junctions, tightening the gut barrier and reducing the increased permeability implicated in celiac disease, IBS, and inflammatory gut conditions.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.
What It Is
Larazotide acetate is an oral peptide that acts locally in the gut lumen. It is minimally absorbed and does not enter circulation in meaningful amounts, which is why it is taken before meals: it needs to be in place when food and antigens like gluten arrive.
How It Works
It tightens the junctions between intestinal cells, reducing the leaky-gut permeability that lets antigens through. Because it works in the lumen rather than the bloodstream, timing it ahead of a meal is what makes it effective.
Who It's For
Adults with barrier-related gut symptoms who want a before-meal adjunct. In celiac disease it is an adjunct for residual symptoms despite a gluten-free diet, not a replacement for the diet.
Who Should Avoid It
Not a substitute for a gluten-free diet in celiac disease. Most common effects are mild GI symptoms such as gas, nausea, and headache. Human efficacy data for non-celiac uses is thin; frame expectations accordingly and discuss with your provider.

Stacking Guide
Stacks Well With
Zonulin receptor antagonist (gut permeability)
Read the Larazotide protocol guide
An oral octapeptide that blocks the zonulin receptor to keep intestinal tight junctions closed. More human trial data than most compounded peptides: Phase 2 showed benefit during gluten challenge; Phase 2b primary endpoint narrowly missed but secondary endpoints were significant. Evidence is celiac-specific.
