Postbiotics: a perspective on their quantification

Precise quantification is essential for measuring the dose of a postbiotic and ensuring consistency across scientific studies, but a gold standard for quantifying postbiotics does not yet exist. In this paper, 15 leading scientists from academia and industry offer globally relevant guidance for postbiotic quantification. The paper originated from a 2024 expert working group held by ISAPP.
