Search and filter this category ↗A marketing category needs an ingredient-level reading
Some products are marketed as postbiotics even when their ingredient is a purified microbial metabolite or a compound such as tributyrin. Scientific terminology is more specific. The ISAPP definition requires inactivated microorganisms or their components with a demonstrated benefit; a metabolite-only supplement does not automatically meet that definition.
Read the evidence limits and sources
Research on bacterial fermentation or butyrate biology cannot establish a digestive benefit from every tributyrin capsule. The stated tributyrin mass is not the same as free butyrate mass. This category therefore needs more formulation-specific evidence before confident symptom or disease claims can be made.
