Synbiotics in Nutrition
Abstract
Synbiotics is a novel approach that combines the benefits of probiotics and prebiotics to promote gut health and overall well-being. The term “synbiotics” implies synergy, and it should be specifically applied to products where the prebiotic component(s) actively promote the growth and activity of the probiotic organism(s). Synbiotics were created to address probiotic survival challenges, with evidence suggesting enhanced upper intestinal survival. This fosters efficient colon implantation and stimulates probiotic and common gut bacteria growth, crucial for maintaining intestinal balance and overall well-being. Probiotics, like specific strains of beneficial bacteria (e.g., Lactobacillus, Bifidobacterium), colonize the gut upon ingestion. They directly engage with the gut microbiome, maintaining microbial balance by outcompeting harmful pathogens, generating antimicrobial compounds, and modulating the immune system, thereby enhancing gut health and immunity. Prebiotics, non-digestible fibers and compounds, serve as nourishment for probiotics and beneficial gut bacteria. Combining probiotics and prebiotics in synbiotics forms a mutualistic relationship. Prebiotics act as a targeted energy source for probiotics, ensuring their survival, expansion, and activity in the gut. Probiotic varieties in synbiotic formulations encompass Lactobacilli , Bifidobacteria species, Saccharomyces boulardii , Bacillus coagulans , among others. Key prebiotics in these formulations include oligosaccharides like fructo-oligosaccharide (FOS), galactooligosaccharides (GOS), xylooligosaccharide (XOS), inulin, and natural sources like chicory and yacon roots. This synergy reinforces a resilient microbiome composition that better withstands disruptions, maintaining intestinal equilibrium. This synergy enhances gut health (gut-brain axis), addressing malnutrition, weight management, metabolic health, and immune system support.
