Akkermansia muciniphila, a key element in the gut microbiome. plays a crucial role in both longevity and metabolism. Akkermansia not only contributes to longevity by promoting gut health and immune resilience but also plays an important role in optimizing metabolism. The primary manner in which Akkermansia is involved in longevity is the role it plays in creating an ideal environment in the gut. This, ultimately, lends to its impact on metabolism. specifically the production of GLP-1, a specialized hormone which serves as a central player in metabolic health. At its core, the role of Akkermansia in promoting longevity is driven by this optimization of metabolism via GLP-1.
