The 2025 SupplySide Global ingredient trade show marked a turning point for postbiotics, as this once-obscure category stepped into the spotlight as a mature, marketable solution for gut health and beyond. According to industry experts at the event, postbiotics are addressing fundamental consumer frustrations with traditional probiotics while opening new formulation possibilities that were previously impossible.

Vaughn DuBow from ADM reported striking consumer research findings: when given a clear definition of postbiotics and how they work, 80% of surveyed consumers said they were more likely to try a postbiotic than a probiotic. This shift reflects growing awareness that could reshape the gut health supplement market in the coming years.

Understanding What Postbiotics Actually Are

Postbiotics—also called parapropiotics, tyndallized biotics, or ghost biotics—are heat-treated or otherwise inactivated probiotic organisms that retain sufficient metabolites to provide beneficial effects in the gut microbiome. Unlike their living counterparts, these inactivated organisms don't require refrigeration or careful handling to remain effective.

The category extends well beyond general gut health applications. At SupplySide Global 2025, ADM showcased postbiotics for sleep and perimenopausal support with promising research results. Verb Biotics presented Keystone Postbiotic, a precision-fermentation product that supports emotional well-being and immunity. IFF Health Solutions demonstrated Calceobiotic, designed to enhance nutrient bioavailability.

Solving the Probiotic Shelf-Life Problem

Traditional probiotics create an inherent consumer frustration. They're sold in both refrigerated and shelf-stable formats, generating confusion from the start. Store them incorrectly and the organisms die. Skip doses and they die. Take them on an empty stomach or with coffee and they die. Consumers watch their investment disappear along with the beneficial bacteria.

This pain point creates substantial opportunity for postbiotics. Because they're already inactivated, storage conditions don't compromise their effectiveness. There's no guilt about forgotten doses affecting viability, no confusion about refrigeration requirements, and no concern about whether the organisms survived manufacturing, shipping, and storage before reaching consumers.

Expanding Formulation Possibilities

Divya Mohan, director of creation, design and development for global health and wellness at ADM, explained that formulating with postbiotics like BPL1 offers remarkable simplicity compared to traditional probiotics. Testing across a pH range of 2 to 9 showed consistent functionality, and postbiotics don't interact negatively with sweeteners, flavors, or colors.

Heat stability opens entirely new product formats. Ultra-heat-treated products like shelf-stable protein shakes and shots can now incorporate gut health benefits without killing the active ingredients during processing. Postbiotics work in "candified" formats like mints and dissolvable strips, both of which appeared on the SupplySide show floor this year.

Early research even suggests potential applications in athletic performance and recovery products. While a "postbiotic-powered pre-workout" may sound unusual, the science indicates this category's versatility extends far beyond traditional digestive health supplements.

Not Every Dead Probiotic Becomes a Postbiotic

The critical question many formulators ask: if heat-killed probiotics are already in existing products, why weren't we calling them postbiotics all along? The answer reveals essential distinctions in this emerging category.

"Not all probiotics retain functionality when they're inactivated," Mohan explained. Identifying which strains maintain beneficial effects after inactivation represents a major focus of current postbiotic research, which typically follows a three-arm study design comparing placebo, live bacteria, and postbiotic versions.

Sometimes this research produces counterintuitive results. Dr. Gene Bruno cited studies involving Akkermansia muciniphila examining effects on glucose control and body fat loss. Researchers found benefits from both probiotic and postbiotic versions, but in one study, the postbiotic showed greater impact than the living strain.

"That might seem counterintuitive, until you realize a lot of probiotic benefits come from short-chain fatty acids and other metabolites," Bruno noted. "When you kill the bacteria, those metabolites can still be present and do their job."

The Rise of Complete Biotic Formulations

The supplement industry has seen increasing interest in prebiotic and probiotic combinations, known as synbiotics, over the past two years. These formulas combine beneficial organisms with the fiber compounds that feed them, offering consumers an all-in-one solution.

At SupplySide Global 2025, the next evolution emerged: formulas combining prebiotics, probiotics, and postbiotics. These blends appeared under various names, including "pre pro post," "complete biotics," or variations on "synbiotic plus" or "ultra." ADM calls their version the "triobiotic."

Some ingredient suppliers now produce both probiotic and postbiotic versions of certain strains, allowing formulators to choose based on product requirements. Others, like Verb Biotics, lean into the advantages of postbiotic stability with standalone products like Keystone.

DuBow reported dramatic increases in consumer awareness: "We've been seeing a hockey stick growth curve in awareness around postbiotics. Just from last year to this year, the number of people saying, 'I've heard about postbiotics, I want postbiotics,' has exploded. I think by next year, we'll see that awareness maximize."

Quality Management for Emerging Categories

As postbiotics transition from niche to mainstream, manufacturers face the same compliance challenges that affect all supplement categories. Product integrity, accurate labeling, and consistent quality control remain essential regardless of whether formulas contain living organisms or inactivated metabolites. Companies entering this emerging market need robust quality management systems that track ingredients, verify supplier credentials, and maintain comprehensive documentation throughout the supply chain.
