What’s the Difference Between Prebiotics, Probiotics, and Postbiotics?

In the realm of digestive health, the terms prebiotics, probiotics, and postbiotics often emerge. Understanding the differences and functions of these elements can empower us to support our gut health and more. Let’s delve into what they are and how they contribute to a balanced gut microbiome and overall wellness.

Prebiotics: Nourishing the Gut Microbes

What Are Prebiotics?

Prebiotics are non-digestible fibers that feed the beneficial bacteria in your gut. By stimulating the growth and activity of these microbes, prebiotics help support a healthy digestive system and contribute to overall well-being. While not all dietary fibers are prebiotics. However, there are several sources for prebiotics. 

Sources of Prebiotics

Naturally found in a wide variety of whole plant foods such as fruits, vegetables, grains, legumes, and seeds, prebiotics are an essential part of a balanced diet. Human breast milk also contains abundant prebiotics, such as HMO, and plays a vital role in establishing healthy gut microbiota in infants.

While a diverse, plant-rich diet provides natural prebiotics, many Western diets often fall short. For those looking for more targeted intake, prebiotics are also available in convenient forms like dietary supplements (e.g., sachets and capsules) and are added to infant formulas and other functional foods for daily use. Morinaga Probiotics has some scientific studies in combination with specific Prebiotics, and their synergistic effects are expected.

Probiotics: Live Beneficial Bacteria

What Are Probiotics?

Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts. Commonly found in fermented foods like yogurt and kefir, or specialized supplements, probiotics help support gut health by balancing the intestinal microbiota, strengthening the gut barrier, and modulating immune function. However, not all live cultures qualify as probiotics. To be defined as a probiotic, the strain must be aligned with the definition. Each probiotic strain functions differently, and its effects depend on both the strain and the amount consumed.*

Types of Probiotic Strains

The most common probiotic strains are Lactobacillus and Bifidobacterium. These strains have been associated with benefits such as improved digestion, enhanced immune response, and overall well-being. Morinaga, a leader in probiotic research, offers proprietary Bifidobacterium strains, and these probiotics are known to support a healthy gut microbiome, improve intestinal function, and strengthen immune health.*

Postbiotics: The New Wave in The Biotic Industry

What are postbiotics?

Postbiotics are non-viable microbial products or byproducts produced by probiotics. This has several discussions but sometimes explains “inanimate microorganisms” and “metabolic waste” of probiotics. These compounds, such as organic acids, peptides, and cell wall components, play an active role in promoting health.

Unlike live probiotics, Morinaga’s postbiotic strain is a heat-killed bacteria making it stable and ideal for use in products where live microbes may not be practical. They’re especially useful in environments where probiotic viability is hard to maintain.

Health Benefits of Postbiotics

Although postbiotics are still an emerging area of scientific research, growing evidence shows they can support gut health, enhance immune function, support the intestinal barrier, and help reduce inflammation. Postbiotics may modulate the gut microbiome in targeted ways, delivering specific health benefits, especially in situations where live probiotics may not be practical.*

Morinaga, as a probiotics manufacturer, has been at the forefront of this research. Our proprietary postbiotic, LAC-Shield, a heat-killed strain of Lacticaseibacillus paracasei MCC1849, retains strong biological activity and provides healthy immune-supporting benefits with multiple pathways.*

Understanding the roles of prebiotics, probiotics, and postbiotics enables us to make informed decisions about managing digestive and immune health, among other benefits. With a variety of options—ranging from nutrient-rich foods to targeted supplements—supporting gut health has never been more accessible.
