For supplement brand owners, postbiotics represent a compelling opportunity to innovate within an already established category. Their stability, versatility, and compatibility with multiple delivery formats make them especially attractive from both a product development and manufacturing standpoint.
In this article, we will explore postbiotic benefits in detail, including what postbiotics are, how they differ from probiotics and prebiotics, their key benefits, formulation and manufacturing advantages, and important considerations for product development.
What Are Postbiotics? Understanding the Basics
The International Scientific Association for Probiotics and Prebiotics (ISAPP) defines postbiotics as:
“A preparation of inanimate microorganisms and/or their components that confers a health benefit on the host.”2Postbiotics: debate continues and the ISAPP definition gains support. ISAPP. Retrieved June 19, 2024 from https://isappscience.org/postbiotics-debate-continues-and-the-isapp-definition-gains-support/.
This definition is important for understanding how postbiotic benefits can be delivered without the need for live organisms.
In practical terms, postbiotics are typically derived from probiotics that have been heat-treated or inactivated, while still retaining their functional properties. Despite not being live microorganisms, postbiotics can still support many of the same wellness outcomes associated with probiotics.
One of the most important postbiotic benefits from a product development standpoint is improved stability. Because postbiotics are not living organisms, they do not face the same sensitivity to heat, moisture, and shelf-life challenges that often complicate probiotic formulations.
Types and Examples of Common Postbiotics
There are two commonly referenced ways to define postbiotics. The first follows the ISAPP definition outlined above. The second refers to metabolites produced by probiotics, which also contribute to postbiotic benefits.
For example, many probiotics produce short-chain fatty acids such as butyric acid, also known as butyrate. These compounds are among the most well-known metabolite-type postbiotics and are often associated with gut health support.
Other examples include enzymes, peptides, and cell wall fragments, all of which can play a role in delivering postbiotic benefits depending on the formulation and intended use.
While both definitions are used within the industry, the ISAPP definition remains the most widely accepted and provides the clearest framework for product development and positioning.
Postbiotics vs. Probiotics vs. Prebiotics: Key Differences for Formulators
Probiotics are live or viable microorganisms that, when consumed in adequate amounts, provide a benefit to the host, primarily by supporting the balance of the gut microbiota. Common probiotic strains include the Lactobacillus, Bifidobacterium, and Bacillus genera.
Prebiotics, in contrast, are non-digestible compounds such as specialized plant fibers and polyphenols that serve as a food source for beneficial bacteria. Well-known examples include fructooligosaccharides (FOS), galactooligosaccharides (GOS), and xylooligosaccharides (XOS).
Postbiotics differ in that they consist of inactivated microorganisms and/or their functional components and metabolites. Unlike probiotics, they do not require viability to deliver their intended effects, which has important implications for formulation and stability.
Each of these biotic categories offers distinct advantages and applications depending on the intended product positioning, delivery format, and target consumer. The table below provides a comparative overview for formulators.
| Factor | Postbiotics | Probiotics | Prebiotics |
| Type | Non-living (heat-treated) probiotics | Live and/or viable microorganisms (bacteria or yeast) | Dietary fibers
Polyphenols |
| Stability | Highly stable | Sensitive to heat and moisture | Stable |
| Storage Requirements | Minimal | Requires controlled conditions | Minimal |
| Formulation Complexity | Low | High | Low |
| Consumer Perception | Emerging category | Well-known | Moderately well-known |
| Use Cases | Gut health, immune support, digestive support, and multiple other applications, depending upon the specific postbiotic, probiotic, or prebiotic being used.

Key Health Benefits of Postbiotics Supplements
Now let’s take a closer look at the health benefits of postbiotics.
While many consumers are already familiar with the health benefits of probiotics, postbiotics offer a complementary approach to supporting overall wellness. These benefits include gut health support, immune system support, anti-inflammatory potential, skin health, cardiometabolic support, and weight management support.
Gut Health Support
Postbiotics have demonstrated the ability to support gut health through multiple mechanisms.3Instituto de Investigación Hospital Universitario La Paz. BIOPOLISClinical Trial to Evaluate the Effect of Regular Consumption of a Heath-treated Postbiotic on the Improvement of Symptoms in People With Mild to Moderate Gastrointestinal Disorders Not Associated With Disease. Retrieved April 15, 2026 from https://www.patlynk.com/trial/NCT05367427. For example, a Bifidobacterium longum ES1 strain has been shown to promote gut comfort. A combination of Lactobacillus salivarius LS97, L. paracasei LC86, and L. acidophilus LA85, delivered in a toothpaste format, has been shown to help modulate the oral-gut microbiome axis,4Rui W, Zhong S, Li X, Tang X, Wang L, Yang J. Evaluating the Role of Postbiotics in the Modulation of Human Oral Microbiota: A Randomized Controlled Clinical Trial. Probiotics Antimicrob Proteins. 2025 Oct;17(5):2942-2952. doi: 10.1007/s12602-024-10238-y. Epub 2024 Mar 19. PMID: 38502383. supporting a balanced microbial environment.
In addition, certain postbiotics, such as L. rhamnosus, have been shown to support tight junction integrity and epithelial barrier function, which are important for maintaining a healthy gut lining.5Ma L, Tu H, Chen T. Postbiotics in Human Health: A Narrative Review. Nutrients. 2023 Jan 6;15(2):291. doi: 10.3390/nu15020291. PMID: 36678162; PMCID: PMC9863882.
Immune System Support
Postbiotics have also been studied for their role in supporting immune function. A Lactobacillus plantarum strain L-137, commercially known as Immuno-LP20®, has been shown to support acquired immune responses in healthy individuals, particularly Th1-related immune activity.6Hirose Y, Murosaki S, Yamamoto Y, et al. Daily Intake of Heat-Killed Lactobacillus plantarum L-137 Augments Acquired Immunity in Healthy Adults. J Nutr. 2006; 136: 3069–3073.
This same postbiotic strain was also shown to promote periodontal health7Iwasaki K, Maeda K, Hidaka K, et al. Daily Intake of Heat-killed Lactobacillus plantarum L-137 Decreases the Probing Depth in Patients Undergoing Supportive Periodontal Therapy. Oral Health Prev Dent. 2016;14(3):207-14. and upper respiratory tract immune function.8Hirose Y, Yamamoto Y, Yoshikai Y, Murosaki S. Oral intake of heat-killed Lactobacillus plantarum L-137 decreases the incidence of upper respiratory tract infection in healthy subjects with high levels of psychological stress. J Nutr Sci. 2013; 2: e39. Likewise, a postbiotic Lactobacillus acidophilus strain L-92 has been shown to support healthy upper respiratory tract immune responses.9Sasai M, Kano C, Sakano K, et al. Effect of Oral Intake of Lactobacillus Acidophilus L—92 on Systemic and Intestinal Immune Parameters—A Randomized, Double—blind, Placebo—controlled, Parallel—group Trial―. 薬理と治療 (Nursing Care and Treatment). 2022;50(9):1699-1707.
Anti-Inflammatory Potential
Certain postbiotics have demonstrated potential to support healthy inflammatory responses. The previously mentioned Lactobacillus plantarum L-137 strain has been shown to support healthy inflammation levels and lipid metabolism in healthy individuals.10Tanaka Y, Hirose Y, Yamamoto Y, et al. Daily intake of heat-killed Lactobacillus plantarum L-137 improves inflammation and lipid metabolism in overweight healthy adults: a randomized-controlled trial. Eur J Nutr. 2020 Sep;59(6):2641-2649.
Likewise, Lactobacillus acidophilus L-92 has been associated with supporting normal inflammatory responses.11Inoue Y, Kambara T, Murata N, Komori-Yamaguchi J, Matsukura S, Takahashi Y, Ikezawa Z, Aihara M. Effects of oral administration of Lactobacillus acidophilus L-92 on the symptoms and serum cytokines of atopic dermatitis in Japanese adults: a double-blind, randomized, clinical trial.

Front Microbiol. 2023; 14:1273861. doi: 10.3389/fmicb.2023.1273861.
Skin Health Support
Are there postbiotics benefits for skin? Emerging research suggests there are. A Lactobacillus acidophilus strain L-92 has been shown to influence T-helper cell responses, which play a role in maintaining overall skin health.
As a result, this postbiotic has been shown to support healthy skin in both adults and children,13Inoue Y, Kambara T, Murata N, Komori-Yamaguchi J, Matsukura S, Takahashi Y, Ikezawa Z, Aihara M.

PMID: 31089460; PMCID: PMC6494655. particularly those with dry, itchy, and redness-prone skin.
Cardiometabolic and Weight Loss Support
A postbiotic Akkermansia muciniphila 001 strain (AKK001™), when combined with butyrate, has been shown to support reductions in body weight, body fat percentage, BMI, and key anthropometric measures, such as waist and hip circumference.17Bruno G, et al. Akkermansia muciniphila 001 (AKK001™) Postbiotic and Butyrate (Tributyrin) Impact on Body Morphology Measures and Metabolic Indicators in an Overweight Population: A Randomized, Controlled Trial. Submitted for publication, 2026. The same study also demonstrated support for metabolic health, including maintaining healthy cholesterol, triglyceride, insulin, and glucose levels already within normal ranges.
Formulation and Manufacturing Advantages of Postbiotics for Supplement Brands
Postbiotics offer several distinct advantages from both a supplement formulation design and manufacturing perspective. These include enhanced stability, greater flexibility across delivery formats, simplified supply chain and storage requirements, and improved compatibility when combined with other functional ingredients.
Stability Across Conditions
In addition to postbiotics’ health benefits, one of the most significant advantages of postbiotics is their stability. Because they are not live microorganisms, they are not susceptible to degradation from heat, stomach acid, or other environmental stressors that commonly affect probiotics.
Flexible Format Compatibility
Due to their inherent stability, postbiotics offer significant flexibility across a wide range of supplement delivery formats. In addition to conventional tablets, capsules, and powders, they can also be incorporated into more specialized formats such as effervescent systems, chewable tablets, and orally disintegrating tablets, including fast-melt or quick-dissolve formats.
This versatility is possible because postbiotics are not subject to the same viability concerns as probiotics, which can be compromised during processing or under certain environmental conditions.
Simplified Supply Chain and Storage
Live probiotics are highly sensitive to environmental conditions, particularly temperature. USP data18<659> Packaging and Storage Requirements. Official Date: 01-May-2017. Retrieved August 29, 2024 from chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.uspnf.com/sites/default/files/usp_pdf/EN/USPNF/revisions/659_rb_notice_english.pdf. indicates that many probiotic strains require storage between 68°F and 77°F to maintain viability, often necessitating temperature-controlled transportation and storage.
Postbiotics do not face these same constraints. Because they are not living organisms, they are far less susceptible to degradation under typical shipping and storage conditions. This significantly simplifies logistics and reduces the need for specialized handling throughout the supply chain.
Ease of Combination with Other Ingredients
Probiotics are often freeze-dried to maintain viability, placing them in a dormant state. However, exposure to even small increases in moisture during formulation can reactivate these organisms, leading to instability and potential loss of potency before the end of shelf life.
Postbiotics eliminate this concern. Their non-viable nature makes them far more tolerant of variations in moisture and environmental conditions. As a result, they can be more easily combined with a broad range of other nutraceutical ingredients without compromising product stability.
Key Formulation Considerations When Using Postbiotics
There are several important considerations when developing postbiotic-based products. These include selecting the appropriate dosage and units of measure, ensuring high-quality ingredient sourcing, and adhering to regulatory and claim requirements.
Dosage and Units of Measure
Live probiotics are measured in colony-forming units (CFU). Heat-treated or pasteurized postbiotics are typically measured in total fluorescent units (TFU), which quantify the total number of inactivated bacterial cells. In some formulations, postbiotics may also be measured by weight in milligrams.
When formulating a product, make sure to identify the exact TFU or milligram dose needed (based upon human clinical research) to substantiate the claim that you plan to make about the postbiotic.
Ingredient Sourcing and Quality
Selecting high-quality postbiotic ingredients is essential for both product performance and credibility. Formulators should prioritize strains evaluated in human clinical studies and shown to support the intended wellness outcomes.
These materials are often proprietary and supplied by established ingredient manufacturers. Using well-characterized, clinically supported strains helps ensure consistency, quality, and alignment with claim substantiation requirements.
Regulatory and Claim Considerations
Postbiotic supplements are subject to the same regulatory framework as other dietary supplements under the Dietary Supplement Health and Education Act of 1994 (DSHEA). Key requirements include proper identity testing, safety evaluation, and manufacturing in compliance with current Good Manufacturing Practices (cGMPs).
From a claims perspective, substantiation should be based on credible scientific evidence, including data supporting the specific ingredient and dosage used. Careful alignment between formulation, supporting research, and marketing claims is essential to maintain compliance.

Frequently Asked Questions about Postbiotics Benefits
What factors should be considered when selecting a postbiotic ingredient supplier?
It is important to select postbiotic ingredients that are supported by human clinical research and aligned with the intended product positioning. These materials are often proprietary and supplied by reputable ingredient manufacturers. Using well-characterized, clinically studied strains helps ensure consistent quality and supports proper claim substantiation.
How do postbiotics impact product shelf life compared to probiotics?
Most dietary supplements are designed to achieve a 24-month shelf life. Because probiotics are live microorganisms, their viability can decline over time, often resulting in greater overages or shorter shelf-life expectations of 12 to 18 months, depending on formulation and storage conditions.
Postbiotics, by contrast, are inactivated through processes such as heat treatment or pasteurization. Because they are not living organisms, they are significantly more stable and are generally well-suited to meet standard shelf-life requirements with fewer formulation constraints.
Can postbiotics be used as a standalone product, or are they better suited for combination formulations?
Postbiotics can be formulated as standalone products or incorporated into combination formulas. Because they are non-viable, they offer greater compatibility with other nutraceutical ingredients while minimizing concerns related to moisture sensitivity and ingredient interactions.
They are also well-suited for combination products, including synbiotic formulations that pair probiotics with prebiotics, giving formulators greater flexibility in product development and market positioning.
