What is postbiotics?
Postbiotics are natural & functional bioactive compounds comprise of microbial-derived metabolites, ie, SCFAs & proteins that confer health benefits*.
Postbiotics over 100 years in Japan
In Japan, postbiotics have been available for over 100 years**, andProfessor Tomotari Mitsuoka*** pioneered in Japan in 1998 to only scientifically develop and study its health effects. (referred in Japan asLactic Acid Bacteria (LAB,aka Probiotics)Metabolitesor Lactobacillus Fermented Extracts)
"Naive" question, profound implication
Researchers and biologists over the years have been trying to answer a seemingly"naive"question:why do probiotics have health effects given that probiotics itself just living microbes and NOT nutrients?
Postbioitics's direct effect
Postbiotics are now widely recognised asthe primary source of health effect of probiotics^andact on directly on host/human****.
Postbioitics: improving absorption disorder for overall health
The recent studies suggest^ that Postbiotics effectively to suppress "bad" bacteria, promote native "good" bacteria growth for restoring gut flora balance and improving absorption disorders, which otherwise induces various diseases includingGI disorders (heartburn, nausea), obesity, constipation, diarrhea, irritable bowel syndrome (IBS), and immune disorders.
