These bacterial preparations are known as "ghost probiotics," "postbiotics," "inactivated probiotics," and now "para probiotics." The benefits of some products have nothing to do with the organism being alive but instead are due to unique cellular components of the bacteria that are there, whether the bacteria is alive or dead. 8 That is the case with A. muciniphila.
But this isn’t entirely bad news. Research shows that in the quest for gut health, prebiotics are just as powerful as probiotics. While probiotics are live beneficial bacteria, prebiotics are the fertiliser for the bacteria you currently have. And as it appears that most of us already carry Akkermansia, it could be that all we need to do is feed them properly. Akoumianakis, I. & Antoniades, C.
