Summary
Kefir and other fermented foods introduce beneficial live microorganisms (probiotics) and bioactive compounds (postbiotics) into the gut. This can modulate the gut microbiome, reduce inflammation, improve gut barrier function, and enhance nutrient absorption, all of which are linked to improved metabolic and immune function, key pillars of healthspan.
Purpose
Modulates gut microbiome to support immune and metabolic health.
