"Recent scientific research underscores the powerful synergy between probiotics, prebiotics, and postbiotic metabolites in restoring gut health and boosting immune resilience. Studies show that short-chain fatty acids (SCFAs), produced during fermentation, strengthen the intestinal barrier, reduce inflammation, and enhance nutrient absorption—laying the foundation for metabolic and immune wellness. At the same time, probiotics such as Lactobacillus casei and Bifidobacterium bifidum have been shown to regulate immune function, support gut integrity, and reduce the risk of allergies and infections."
