Postbiotics are beneficial metabolic byproducts produced by probiotic microorganisms during fermentation, or components of inactivated microbial cells. These compounds, such as short-chain fatty acids, enzymes, and peptides, can modulate host immune responses, enhance gut barrier function, and influence metabolic pathways. They may offer a more stable and targeted approach to improving gut health and systemic well-being compared to live probiotics.
Verdict
Promising gut modulator; consider for targeted digestive and immune support.
