Roseburia faecis: The Gut Microbe That Supports Digestive Health

Roseburia faecis is a prominent gut microbe best known for its role in butyrate production and fiber metabolism. The bacterium roseburia faecis ferments dietary fibers to generate butyrate, a powerful short-chain fatty acid that nourishes colonocytes, helps maintain the integrity of the gut barrier, and supports balanced inflammation. By contributing to the breakdown of complex fibers such as resistant starches and certain plant polysaccharides, roseburia faecis supports a healthy fermentation environment that can promote regular digestion and comfortable post-meal experiences. To nurture roseburia faecis and other beneficial microbes, focus on a diverse, fiber-rich diet. Include a mix of soluble and insoluble fibers from oats, legumes, apples, berries, leafy greens, onions, garlic, artichokes, and flaxseeds, and consider adding resistant starch sources like cooled potatoes or rice. Hydration and gradual increases in fiber help your gut microbiome adapt. You can track how well roseburia faecis and related bacteria respond to dietary changes with InnerBuddies, where the Gut Microbiome Health Index provides a 0–100 score and where you can compare your results against a healthy cohort. See how this works on the InnerBuddies microbiome test page for a practical starting point. InnerBuddies makes it possible to go beyond general guidelines. The platform organizes all bacterial metabolic functions into categories, labeling each as positive or negative, so you can see where roseburia faecis contributes to key butyrate pathways and how your functional profile stacks up against a healthy reference. The Target Group analysis dives deeper into how the microbiome supports specific goals— Healthy Aging, Endurance Sport, or Skin & Hair Health, among many others—helping you understand the relevance of roseburia faecis within your personal context. For nutrition decisions tailored to you, InnerBuddies offers personalized nutrition advice based on 3-day food diaries aligned with stool sample data, plus personalized probiotic and prebiotic recommendations.
