Collinsella is a genus of gram-positive bacteria within the Actinobacteria phylum, first identified in the late 1990s. Initially categorized as part of the human gut microbiota, it has garnered attention for its potential role in human health and disease. Research has increasingly focused on Collinsella for its association with various metabolic processes, including the metabolism of carbohydrates and fatty acids, which may influence energy balance and gut health. Notably, shifts in Collinsella abundance have been linked to conditions such as obesity, metabolic syndrome, and other gastrointestinal disorders, making it an important biomarker in the study of microbiome-related health. As understanding of the gut microbiome evolves, Collinsella's significance continues to unfold, highlighting its potential as a target for therapeutic interventions and a marker for assessing health and disease states.

Elevated levels of Collinsella may indicate an imbalance in gut microbiota, potentially linked to dietary factors like high carbohydrate intake or reduced fiber consumption. This elevation could suggest an adaptive response to an altered gut environment, which may have implications for metabolic health. Conversely, low levels of Collinsella might signify an overall reduction in microbial diversity or dysbiosis, which can compromise gut barrier function and contribute to inflammatory conditions or metabolic disturbances. Maintaining optimal levels of Collinsella is essential for a healthy gut ecosystem and overall well-being.

Collinsella is a key biomarker featured in the Gut Zoomer test, which analyzes the gut microbiome by assessing over 170 microbial species, along with significant metabolic and inflammatory markers. This beneficial bacterium plays a critical role in maintaining gut health and has been associated with metabolic processes and immune function. By including Collinsella, the Gut Zoomer provides valuable insights into microbial diversity and its impacts on overall health, helping practitioners tailor personalized approaches for optimizing gut function and addressing specific health concerns.
