Peptides marketed for gut health

These are compounds sold for gut health — this is not a recommendation list, and nothing here is ranked. Of the 2 we track with this claim, 1 has any registered human trial at all, 0 have one that actually studied gut health, and 0 are FDA-approved for any indication.

Two of these came out of gastrointestinal research originally, so the connection is not invented. "Leaky gut" as sold online is a broader idea than the specific intestinal-permeability measures used in the laboratory work.

Marketed for is not tested for

A compound can be sold for gut health and studied for something else entirely — that is the most common pattern on this site, not the exception. A row saying "trials, but not for gut health" means registered studies exist and none of them asked this question. It is not a claim that the compound does nothing.
