claimData were analyzed using a 2-way analysis of variance with estrogen status and diet as factors, followed by post hoc tests when P Results RS supplementation induced distinct clustering in bacterial β -diversity, enriched beneficial genera including Bifidobacterium, Dubosiella, Bacteroides, and Akkermansia, and reduced proinflammatory Clostridium sensu_stricto_1 in estrogen-deficient mice.
