What Is a Postbiotic?

Postbiotics are officially defined and distinct from probiotics

The International Scientific Association of Probiotics and Prebiotics (ISAPP) consensus statement defines a postbiotic as a preparation of inanimate microorganisms and/or their components that confers a health benefit on the host - distinct from live, viable probiotic organisms.

Consensus statement
Salminen et al., Nature Reviews Gastroenterology & Hepatology (2021)
What Is a Postbiotic?

Postbiotic proteins support gut barrier activity

A review of postbiotic-derived bacterial proteins (including p40 and p75) found they support intestinal barrier activity and protect epithelial tight junctions, suggesting a mechanism for gut-lining support even without live bacteria.

Review
Bingöl et al., Microorganisms (2024)
What Is a Postbiotic?

Postbiotics act through defined pathways without live-organism risk

A review of postbiotics and paraprobiotics found these non-viable microbial derivatives act through defined immune-metabolic pathways that enhance epithelial barrier function and modulate inflammatory signalling, without the infection risk or viability concerns of live probiotics.

Review
Pavithra et al., Archives of Microbiology (2025)
MCC1849 & Cold-Like Symptom Support

24-week trial found fewer cold-like symptom days

In a randomized, double-blind, placebo-controlled trial of 200 healthy adults, 24 weeks of heat-killed Lacticaseibacillus paracasei MCC1849 significantly reduced the number of days of stuffy nose and cold-like symptoms compared with placebo.

Human RCT
Sato et al., Nutrients (2023)
MCC1849 & Cold-Like Symptom Support

Improved flu vaccine antibody response in the oldest-old

In a randomized, double-blind trial in two nursing homes, heat-killed MCC1849 given before influenza vaccination did not significantly change antibody responses overall, but among participants aged 85 and older, antibody responses that were impaired in the placebo group were improved.

Human RCT
Maruyama et al., International Journal of Food Sciences and Nutrition (2016)
MCC1849 & Cold-Like Symptom Support

4-week trial shows the immune mechanism behind the effect

A randomized, double-blind, placebo-controlled trial of 100 healthy adults found that 4 weeks of heat-killed MCC1849 significantly increased CD86 expression on plasmacytoid dendritic cells and interferon-alpha, -beta and -gamma gene expression versus placebo, offering a mechanism for its symptom benefits.

Human RCT
Kato et al., Nutrients (2024)
MCC1849: How It Activates Immunity

Directly activates human immune cells in the lab

Heat-killed MCC1849 cocultured with human peripheral blood mononuclear cells was phagocytosed by, and significantly increased activation markers CD86 and HLA-DR on, plasmacytoid dendritic cells - a key first-responder immune cell type.

Mechanistic study
Li et al., Food Science & Nutrition (2024)
MCC1849: How It Activates Immunity

Boosted gut antibody production in a mouse model

Orally administered heat-killed MCC1849 increased antigen-specific IgA secretion in the small intestine, serum and lungs of mice, and increased the proportion of IgA-producing B cells and follicular helper T cells in gut-associated lymphoid tissue.

Preclinical study
Arai et al., PLoS One (2018)
MCC1849: How It Activates Immunity

A decade of research on how MCC1849 works

A review of heat-killed MCC1849 research describes its immunomodulatory effects as working through activation of dendritic cells and other innate immune pathways, and discusses its use as a stable, food-compatible postbiotic ingredient.

Review
Maehata et al., International Journal of Immunopathology and Pharmacology (2021)
Safety & Tolerability

High-dose 4-week human trial found no adverse events

In 20 healthy adults given 250 billion heat-killed MCC1849 cells per day for 4 weeks - many times a typical dose - no adverse events and no clinically meaningful changes in blood pressure, blood or urine parameters were observed.

Human safety study
Wada et al., Food Science & Nutrition (2025)
Safety & Tolerability

Immuno-LP20 safety confirmed at high dose and long term

Human studies of Immuno-LP20 (heat-killed Lactiplantibacillus plantarum L-137) found no adverse events at a high dose (50mg/day for 4 weeks) or with long-term daily use (10mg/day for 12 months), with no signs of immune exhaustion.

Human safety study
Nakai et al., Journal of Immunotoxicology (2021)
Safety & Tolerability

Probiotic-family caution is real for certain conditions

A clinical review of probiotic use in gastrointestinal disorders notes that, while generally well-tolerated, caution has to be exercised in immunocompromised and critically ill individuals - consistent with this product's own labelled contraindication.

Review
Elangovan & Fischer, Current Opinion in Clinical Nutrition and Metabolic Care (2020)
Lactiplantibacillus plantarum L-137 (Immuno-LP20)

Original 12-week trial found improved immune-cell activity

In a randomized, double-blind, placebo-controlled trial of 60 healthy adults, 10mg/day of heat-killed L-137 for 12 weeks significantly increased T-cell proliferation and the Th1:Th2 immune balance versus placebo, at the same dose used in this product.

Human RCT
Hirose et al., The Journal of Nutrition (2006)
Lactiplantibacillus plantarum L-137 (Immuno-LP20)

12-week trial showed benefits for skin hydration

In a randomized, placebo-controlled trial of 80 adults, daily heat-killed L-137 improved skin water content and reduced water loss versus placebo over 12 weeks, particularly in participants with drier skin - an example of the gut-body connection.

Human RCT
Yoshitake et al., Frontiers in Medicine (2022)
Lactiplantibacillus plantarum L-137 (Immuno-LP20)

Immune signalling from L-137 traced to a specific pathway

Heat-killed L-137 was found to upregulate hyaluronic acid production in skin cells via interferon-gamma and TNF-alpha signalling in mouse studies, illustrating one molecular pathway by which this heat-killed bacterium influences the body beyond the gut.

Preclinical study
Nakai et al., Microbiology and Immunology (2019)
How Postbiotics Work

Postbiotics help crowd out unwanted bacteria

A review of probiotic-host immune crosstalk describes how beneficial bacteria and their components stimulate antimicrobial peptide production and can inhibit quorum sensing in competing microbes, helping support a balanced gut microbial community.

Review
Ren et al., Comprehensive Physiology (2026)
How Postbiotics Work

Microbial metabolites support antioxidant and barrier defenses

A review of probiotics, synbiotics and microbial metabolites describes how bioactive compounds from beneficial bacteria help regulate the body's own antioxidant enzyme systems and reinforce epithelial barrier function as part of a broader host-microbe partnership.

Review
Adhikary et al., Molecular Nutrition & Food Research (2026)
How Postbiotics Work

L-137 shown to calm inflammation in a diet-induced model

In mice fed a high-fat diet, heat-killed L-137 reduced weight gain and downregulated inflammation-related genes in fat tissue, suggesting a broader anti-inflammatory mechanism for this heat-killed bacterium beyond its immune effects.

Preclinical study
Yoshitake et al., Bioscience of Microbiota, Food and Health (2020)
Broader Evidence on Probiotics & Cold Risk

Large network meta-analysis of 100,000+ adults

A 2025 systematic review and network meta-analysis of 107 trials in over 101,000 adults found multi-strain probiotics among the more effective nutritional supplements for reducing the incidence, duration and severity of respiratory tract infections, with no increase in adverse events.

Network meta-analysis
Zhu et al., EClinicalMedicine (2025)
Broader Evidence on Probiotics & Cold Risk

Meta-analysis: modest but real reduction in infection days

A systematic review and meta-analysis of 42 trials in over 9,000 non-elderly adults found orally ingested probiotics modestly reduced the risk, total days, duration and severity of respiratory tract infections compared with placebo.

Meta-analysis
Coleman et al., Advances in Nutrition (2022)
Broader Evidence on Probiotics & Cold Risk

Fermented probiotic dairy linked to lower cold risk

A meta-analysis of 22 randomized trials in over 10,000 participants found probiotic fermented dairy products were associated with a significantly lower risk of respiratory tract infections, including a lower risk of the common cold specifically.

Meta-analysis
Rashidi et al., Nutrition Journal (2021)
Beyond Symptom Counts

Quality-of-life scores improved alongside immune markers

In the same 12-week trial establishing Immuno-LP20's immune effects, participants' self-rated health-related quality-of-life scores improved significantly more in the active group than placebo by week 8.

Human RCT
Hirose et al., The Journal of Nutrition (2006)
Beyond Symptom Counts

Long-term use linked to a healthier gut microbial ratio

In the same long-term Immuno-LP20 safety study, 12 months of daily use was associated with a significantly lower Firmicutes-to-Bacteroidetes ratio and higher fecal short-chain fatty acid levels versus baseline - both markers linked to gut balance.

Human safety study
Nakai et al., Journal of Immunotoxicology (2021)
Beyond Symptom Counts

Even at high doses, standard health markers stayed normal

In the same high-dose MCC1849 safety trial, anthropometric measurements, blood pressure, and blood and urine chemistry all stayed within normal ranges throughout the 4-week study, reinforcing the ingredient's tolerability.

Frequently asked questions

What is CanPrev Post-Biotik Immunobiotics and what does it do?

It's a capsule combining 20 mg of Lacticaseibacillus paracasei MCC1849 and 10 mg of Immuno-LP20 (Lactiplantibacillus plantarum L-137) per capsule. It helps support and maintain immune function and helps reduce the incidence of cold-like symptoms.

Is this a probiotic or a postbiotic?

It's a postbiotic. Both strains are heat-killed (inactivated) bacteria, not live cultures - CanPrev's own labelling describes it as 'Postbiotics · Microbe-Sourced · Heat-Killed Bacteria.'

How do I take it?

Adults take 1 capsule per day, or as directed by a health care practitioner. Take at least 2-3 hours before or after antibiotics.

How long does one bottle last?

Each bottle contains 30 capsules - at the recommended dose of 1 capsule per day, that's a full 1-month supply.

Is it vegan?

Yes - the capsule and formula are plant-derived (vegetable capsule, acacia, vegetable-grade magnesium stearate). The label also carries a milk allergy caution, because the postbiotic strains are cultured using dairy-based fermentation media; there is no dairy ingredient in the finished formula.

Who should use caution, or not use it?

Do not use if you have an immune-compromised condition (e.g. AIDS, lymphoma, patients undergoing long-term corticosteroid treatment) or a milk allergy. Consult a health care practitioner before use if you have a fever, vomiting, bloody diarrhea or severe abdominal pain, and stop use if digestive upset persists beyond 3 days.
