Microbial Metabolites
Microbial metabolites are gut fermentation products like SCFAs—driven by fiber and plant diversity, with effects on metabolism and signaling beyond digestion.
Microbial metabolites are chemicals gut bacteria produce when fermenting fiber—short-chain fatty acids, vitamins, bile acid transformations, and signaling molecules that reach the liver and brain. Low fiber intake shrinks metabolite output even if calories look adequate.
Polyphenol-rich plants can shift which metabolites dominate.
Common questions
-
Can you feel microbial metabolites working?
Not directly—regularity, gas during ramps, energy stability, and lab trends are indirect signals. Consistent fiber beats chasing a single metabolite supplement.
