Technological advancements in bacterial DNA sequencing have
led to a boom in microbiome research, enabling the identification
of how keystone bacterial strains function in the gut to impact
health throughout the body.
2 key functions are
critical to a healthy
gut microbiome.
Maintenance of the protective gut barrier mucin layer
Production of beneficial metabolites, such as butyrate
Precise bacterial strains
Precise bacterial strains are at the forefront of next generation probiotics because of their ability to perform key functions.
Akkermansia
muciniphila
Akkermansia muciniphila has appeared in over 2,000 scientific publications, and abundance of this strain has been associated with healthy weight1, maintaining intestinal integrity2, and improving metabolic disorders such as insulin resistance3.
Akkermansia muciniphila is estimated to make up 1-4% of a healthy human gut microbiome, making it one of the most abundant single species. The primary function of Akkermansia muciniphila is to support healthy mucin layer turnover in the intestines, and thus strengthen the intestinal lining. Furthermore, this process releases short chain fatty acids such as acetate and propionate, that support the abundance and diversity of other health-promoting microorganisms in the gut.
Clostridium butyricum
Clostridium butyricum digests dietary fibers and stimulates butyrate production, a short-chain fatty acid associated with modulating intestinal immune homeostasis, enhancing gut barrier function, and reducing inflammation4.
Administration of the human gut symbiont Clostridium butyricum appears promising in the management of gastrointestinal symptoms, but research also indicates potential indirect effects to brain and metabolic health5.
Emerging research shows targeting the microbiome may offer a cascade of health benefits well beyond the gut.
