Nov 04, 2025

1. What is Active and Inactive Probiotics?

Probiotics is a type of beneficial microorganisms that support digestive and immune health. Currently Probiotics exist in two main forms - Active probiotics (live bacteria) and Inactive probiotics (also called heat treatment probiotics or probiotic metabolites).

 

Active probiotics can colonize the gut and improve probiotics for gut health, while inactive probiotics are non-viable but still provide biological benefits such as immune regulation and anti-inflammatory support. Both are widely used in probiotic powder and probiotic supplements, across the nutrition industry, meanwhile some inactived probiotics can wildely used in Daily Health Products like Mouthwash, toothpaste, cosmetics.
