Gut health discussions often blur the distinctions between prebiotics, probiotics, and postbiotics. Each plays a distinct role.
Prebiotics
Prebiotics are fibers that feed beneficial gut bacteria, promoting their growth and activity.
Probiotics
Probiotics are live microorganisms consumed through foods or supplements. Their effects depend on strain viability and colonization potential.
Postbiotics
Postbiotics are metabolic by-products produced by gut bacteria, including short-chain fatty acids, peptides, and signaling molecules.
Importantly, prebiotics drive postbiotic production, making them foundational to gut health.

Why This Distinction Matters
Without adequate prebiotic intake, probiotic organisms lack the fuel needed to exert meaningful effects. Supporting the microbiome begins with nourishing existing beneficial microbes.
