Talking Biotics: the Difference Between Prebiotics, Probiotics, Postbiotics, and Synbiotics

In the world of gut health and the microbiome, terms like prebiotics, probiotics, postbiotics, and synbiotics have become commonplace, but most people don’t understand what each one means. Though their names might sound similar, each one plays a distinct and vital role in supporting a healthy gut and overall well-being. So let’s start at the beginning. ‘Biotic' simply means related to or resulting from living things. Now let’s explore the differences between these biotics, and how they work together to promote a balanced and robust gut microbiome.


Prebiotics aren’t living organisms (like probiotics are), but rather non-digestible fibers and compounds that serve as a nutrient source for beneficial bacteria residing in your gut. By fueling the growth and activity of these "good" bacteria, prebiotics help maintain a balanced and diverse microbiota. Common sources of prebiotics include certain fibers like inulin and oligosaccharides found in foods such as garlic, onions, bananas, and whole grains.

If you want to make sure you’re getting enough prebiotics, try Polyphenol Booster. This supplement is considered a prebiotic because it helps shape the environment in the gut microbiome. By doing so, it benefits the good bacteria, like Akkermansia muciniphila, and promotes a healthy gut.


Probiotics, on the other hand, are live microorganisms, predominantly beneficial bacteria and sometimes yeast, that provide various health benefits when consumed in adequate amounts. These live cultures work in harmony with the existing gut microbiota, reinforcing the population of good bacteria and displacing harmful ones. Probiotics can be found in fermented foods like yogurt, kefir, sauerkraut, and kimchi..

Of course, probiotics can also be taken as supplements, and we have recommendations for you based on what you’re looking to address…

  • For improving your gut health and strengthening your gut lining, try Akkermansia.
  • For improving your metabolism, reducing sugar cravings, breaking down carbs more efficiently, and sustaining your energy levels, check out Metabolic Daily.
  • To lower glucose spikes and A1C, reduce blood sugar, and minimize post-meal slumps, we recommend Glucose Control.
  • And for alleviating GI discomfort such as gas, bloating, diarrhea, and constipation, you want to take Butyricum.

Postbiotics, though less widely known, are gaining attention as a crucial aspect of gut health. Unlike prebiotics and probiotics, postbiotics aren’t whole organisms but rather the bioactive compounds produced by probiotics during their metabolism. These compounds include short-chain fatty acids, peptides, organic acids, and various enzymes that possess diverse health-promoting properties. Postbiotics play an essential role in bolstering the gut's barrier function, modulating the immune system, and exerting antimicrobial effects against harmful pathogens.

Examples of postbiotics include short-chain fatty acids (SCFAs) such as acetate, butyrate, and propionate. Butyrate-producing probiotics are a great tool for a whole host of health benefits. You can read more about butyrate here.


As the name suggests, synbiotics are a synergistic combination of prebiotics and probiotics. By providing both the necessary nourishment (prebiotics) and live beneficial microorganisms (probiotics), synbiotics aim to optimize the survival and activity of probiotics in the gut, enhancing their potential health benefits. This dynamic duo creates an environment in which probiotics can flourish and deliver their therapeutic effects more effectively.

So there you have it…pre-, pro-, post-, and syn-biotics. Understanding these elements empowers you to make informed choices to support a healthy microbiome. By incorporating prebiotic-rich foods into your diet or taking Polyphenol Booster, consuming probiotic-rich fermented products or a probiotic, and considering synbiotic combinations, you can create a flourishing microbial community that contributes to your overall well-being.

Cheers to your gut health!
