简要总结
The purpose of the study is to determine the effects of both an anthocyanin-rich polyphenol blend and an anthocyanin-rich polyphenol blend combined with a prebiotic blend on fecal microbiota metabolism (assessed by gas chromatograph - mass spectrometry (GC-MS) headspace analysis) and fecal microbiota composition (assessed by next generation sequencing).
