Larazotide

Larazotide is an octapeptide being developed to treat conditions involving increased intestinal permeability, such as celiac disease. It works by regulating tight junctions in the gut.

In the literature, Larazotide appears most often in work focused on gut health and healing. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

Larazotide is catalogued here under powder peptides. Coverage of this compound varies in quality and depth, and much of it remains early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
