Akkermansia muciniphila

A higher abundance of Akkermansia was associated with lower obesity risk in an American Gut Project analysis. A cited 2020 Gut Microbes study reported increased whole-body energy expenditure and fecal energy excretion in diet-induced obese mice after pasteurized Akkermansia muciniphila. A cited 2017 Nature Medicine study reported metabolic improvements in obese and diabetic mice from either a purified membrane protein from Akkermansia muciniphila or the pasteurized bacterium. Akkermansia is described as functionally important and without a redundant microbial substitute. Akkermansia muciniphila is a strict anaerobic bacterium within Verrucomicrobia. The article argues that only live Akkermansia delivers the complete biological benefits attributed to the strain. Akkermansia muciniphila is a keystone gut species that resides in the mucin layer. Scientific understanding of Akkermansia remains early and incomplete. Low Akkermansia is associated with metabolic, inflammatory, or immune problems, but the article distinguishes association from proof of functional restoration. Human evidence cited includes a 2019 proof-of-concept exploratory supplementation study in overweight and obese vo…
