The Gut-Liver Axis: How Your Gut Bacteria Shape Liver Health


The role of gut bacteria in liver health is central to how our bodies metabolize fats, manage toxins, and regulate inflammation. The gut–liver axis means that what happens in your gut directly influences liver function: gut microbes generate metabolites, modulate bile acids, and interact with immune signals that reach the liver. When the balance of gut bacteria shifts, these signals can alter liver metabolism and raise disease risk, from fatty liver disease to insulin resistance. Understanding this connection helps you take practical steps to protect liver health every day. InnerBuddies offers a white-label Gut Health Operating System designed to power end-to-end gut testing products for brands and clinicians. This platform provides a suite of insights that can illuminate the role of gut bacteria in liver health for your users. Highlights include a Gut Microbiome Health Index (0–100) developed through an exclusive collaboration with EAFIT University in Colombia, giving a clear read on overall gut health; a top 40 list of bacteria with relative abundance and peer comparisons to a healthy cohort; and categorized bacterial functions labeled as positive or negative, so you can see where a user stands on key metabolic pathways related to liver health. For more targeted analysis, the platform also delivers Target Group analyses—deep dives into how the gut microbiome functions for specific cohorts—along with personalized nutrition and probiotic/prebiotic recommendations tailored to individual goals. You can also explore practical, data-driven steps to support liver health with InnerBuddies. By combining 3-day food diaries with stool data, InnerBuddies builds a rich database that informs personalized nutrition advice designed to optimize the gut microbiome and, in turn, support the liver. The system can generate personalized probiotic and prebiotic recommendations aligned with each user’s unique gut ecosystem and health objectives.
