Complete Postbiotic Matrix
Also known as: Postbiotic complex, Microbial metabolites, Non-viable bacterial components, Metabolic byproducts from probiotic fermentation, Postbiotic Matrix
Overview
A Complete Postbiotic Matrix refers to a supplement containing non-viable bacterial components or metabolic byproducts derived from probiotic fermentation. These postbiotics can include substances like short-chain fatty acids (SCFAs), enzymes, and cell wall fragments. They are sourced from fermented foods such as kimchi and kefir, as well as the gut microbiota. Research into postbiotics is an emerging field, with the first ISAPP consensus definition published in 2021. While the concept shows promise, current evidence is limited, primarily consisting of animal studies and a few human RCTs, with a scarcity of systematic reviews specifically focused on postbiotics. Most research in this area has been centered around probiotics and synbiotics, making it difficult to draw definitive conclusions about the specific effects of postbiotic matrices.
Benefits
Current evidence for the benefits of 'Complete Postbiotic Matrix' specifically is limited, and findings are largely extrapolated from general postbiotic research. Animal studies suggest potential improvements in gut health, such as enhanced intestinal barrier function through the upregulation of ZO-1. Some mouse models indicate immune modulation, specifically an elevation of IL-10. A meta-analysis focusing on probiotics and synbiotics suggests a potential impact on metabolic markers, with observed reductions in leptin and increases in adiponectin. However, the inclusion of postbiotics in these studies is variable. Additionally, a probiotic meta-analysis showed non-significant improvements in bone mineral density (BMD). Overall, the evidence remains preliminary and requires further verification through dedicated, high-quality RCTs focusing specifically on postbiotic matrices.
How it works
Postbiotics are believed to exert their effects through several primary pathways. These include the modulation of TLR2/4 receptors and the regulation of the NF-κB pathway, both of which play crucial roles in immune response and inflammation. Additionally, SCFAs, a common component of postbiotic matrices, can mediate epigenetic modifications. The absorption of postbiotics varies depending on the size of the component molecules. SCFAs, for instance, are readily absorbed in the colon, while larger molecules may act locally within the gut. These mechanisms collectively contribute to the potential health benefits associated with postbiotic consumption.
Side effects
The consumption of postbiotic matrices is generally associated with a mild side effect profile. Common adverse effects may include mild gastrointestinal discomfort, such as bloating and gas. Serious adverse events have not been reported in available clinical trials. However, there are theoretical concerns regarding immune modulation in immunosuppressed patients, suggesting a need for caution in this population. As of now, there are no established contraindications for postbiotic use. Further research is needed to fully elucidate the safety profile and potential interactions of postbiotic matrices, especially in vulnerable populations.
Dosage
Effective dosage guidelines for Complete Postbiotic Matrix are not yet firmly established due to the variability in formulations and the limited number of dedicated clinical trials. Probiotic meta-analyses often use the equivalent of 10^9 to 10^11 CFU, which may serve as a reference point, but direct comparisons are challenging. It is typically recommended to take postbiotics with meals. Heat-killed lysates offer stability advantages over live probiotics, potentially influencing the form and delivery of the supplement. Given the current state of research, it is crucial to adhere to manufacturer recommendations and consult with a healthcare professional to determine an appropriate and safe dosage.
FAQs
How long until I see results?
Animal studies suggest that effects may be observed within 2-4 weeks of consistent use. However, human trials are needed to confirm these findings.
What are the advantages of postbiotics compared to live probiotics?
Postbiotics avoid the risks associated with colonization by live bacteria. However, they lack the long-term viability and adaptability of probiotics within the gut environment.
Is there a synergistic effect between postbiotics and prebiotics?
There is a theoretical benefit to combining postbiotics with prebiotics, but this has not been definitively proven in clinical trials. More research is needed.
Are postbiotics safe for long-term use?
Current research indicates that postbiotics are generally safe, with mild side effects reported. However, long-term safety data is still limited, and caution is advised for immunosuppressed individuals.

The findings indicated improved RQLQ scores, suggesting a potential benefit of probiotics in managing allergic rhinitis symptoms. However, the analysis also noted high heterogeneity among the included studies, which limits the strength of the conclusions.
- https://pubmed.ncbi.nlm.nih.gov/36538981/ – This systematic review and meta-analysis of 42 RCTs examined the impact of probiotics and synbiotics on metabolic markers. The results showed a decrease in leptin levels and an increase in adiponectin levels, suggesting a potential role for these interventions in metabolic regulation. However, the inclusion of postbiotics varied across the studies, making it difficult to isolate the specific effects of postbiotics.
