Introduction:
In recent years, gut health has become a focal point in conversations about wellness, with probiotics and prebiotics taking center stage. But there’s a new player on the scene that's gaining traction in both scientific circles and consumer markets: postbiotics. As researchers delve deeper into the complex world of the human microbiome, postbiotics are emerging as a powerful tool to support health in ways we’re only beginning to understand.
What are Postbiotics?
Postbiotics are bioactive fermented probiotic microbial-derived molecules. Probiotics are live microbials and prebiotics are microbial fibers that are eaten by microbials, but postbiotics are dead metabolites such as short-chain fatty acids, peptides, polysaccharides, and cell wall material such as peptidoglycan. Such kinds of molecules are generated as a result of healthy microbes fermenting food fiber or other prebiotics in the gut.
These are butyrate, acetate, and propionate-short chain fatty acids the body metabolizes for gut integrity as well as immune function. There are others made up of bacteriocins (host antimicrobial peptides), enzymes, and metabolites, which one can employ in modulation of inflammation as well as even mood.

The Microbiome Connection
Microbiome refers to the trillions of microbes that colonize and inhabit the human body, most of which are densely populated gut microbiome. Microbes directly affect our immunity, metabolism, and even brain via the mechanism of gut-brain axis.
Probiotics were once used to implant microbiomes but with the provision of—I.e., not everything that's being called a "probiotic" will end up surviving and colonizing in the gut. Postbiotics have none of those because postbiotics aren't living microbes. They will not be deactivated by refrigeration or by taking care and will thus be stable and easy to handle in contributing to food products and supplements.
Health Effects of Postbiotics
Previous studies show postbiotics have comprehensive effects on health:
Improved Gut Barrier Function: Postbiotics maintain colonic epithelium integrity and resultant decrease in permeability (so-called "leaky gut"). For instance, butyrate maintained colonocyte function (colon cells) and improved tight junction integrity.
Anti-inflammatory Activity: Postbiotics have anti-inflammatory activity, which may be useful in treatment of chronic disease such as inflammatory bowel disease (IBD), allergy, and obesity.
Immune Health: Postbiotics suppress hyperimmunity and boost innate immunity and are thus capable of suppressing autoimmune disease.
Metabolic Function: Some postbiotics have been shown to modulate glucose and lipid metabolism and are thus pivotal in diabetes and cardiovascular well-being.
Emotional Well-being: Postbiotic butyrate is also instrumental in controlling mood and cognition through gut-brain axis by suppressing neuroinflammation and increasing release of serotonin.
Why Postbiotics Are Crucial Today
The advantage of postbiotics is that it is stable, non-toxic, and bioactive. Environmental conditions like live probiotics cannot metabolize them and thus possibly more effective to emerge as products which shall have longer shelf-life. The patients already being immunocompromised, the patients they can spare from ingestion of live probiotics, can be as safe with postbiotics.
Other than that, as there are better ways of dividing the microbiome and studying microbe metabolism, now it is simpler to find more postbiotic molecules that offer some specific benefit to health. That allows precision medicine and personal nutrition to exist, whereby one's supplementation with postbiotics is tailored based on one's own individual microbiome print.
Postbiotics Available on the Market
Food and dietary supplement company manufacturers are not far behind. Postbiotic supplements are entering the market today in the form of functional drinks, digestive health supplements, and even cosmeceutically applied products. Postbiotics were years ago already decades ago on the market in Japan and Europe and actually in pediatrics and geriatrics.
Regulation looms in the distance. Already, many countries are beginning to approve postbiotics as new functional food ingredients. Always there is the possibility for harmonized definition, test methods, and clinical data.
Final Thoughts
Postbiotics are not in the same wagon as prebiotics and probiotics—those are in a follow-up series of activity. Think of them as a spin-off of being able to have a healthy microbiome. To be able to sense and react to these molecules, we're beyond seeding the gut with microbes and being able to hold on and maximize what they can do.
As we propel science forward and onward, we can turn to the development of "postbiotic therapy" as a means of eradicating chronic disease, enhancing mental acuity, and overall wellness. From foods that have been fermented to the nutraceutical explosion, postbiotics are a beacon on the distant horizon of intestinal health. Report this page
