are polyphenols prebiotics
Polyphenols and probiotics both support gut health but work differently: probiotics add live beneficial bacteria, while polyphenols act as prebiotic-like compounds that feed and reshape your existing microbiota. Research shows they are complementary rather than competing, and probiotics can even ferment polyphenols into more beneficial metabolites. This guide compares mechanisms, evidence, food sources, safety, and whether combining them makes sense.
