Emerging science points to a potential link between microbial deficiency in depression and mood regulation via the gut-brain axis. Bacteria in the gut produce metabolites and signals that influence brain chemistry, inflammation, and the stress response. When the gut microbiome experiences a deficiency in diversity or functional balance, mood and energy can be affected. This page explores how the gut-brain axis works, what research is revealing about microbial deficiency in depression, and practical steps you can take to nurture a healthier microbiome. InnerBuddies offers a white-label Gut Health Operating System designed to power advanced microbiome testing products for brands and direct consumers. Key features include a Gut Microbiome Health Index (a 0–100 score developed under an exclusive IP deal with EAFIT University in Colombia) and detailed insights into Bacteria Abundances, including a top 40 list that shows how you compare against a healthy cohort. The platform also categorizes Bacteria Functions, labeling each as positive or negative and letting you compare performance on each functional category to a healthy baseline. With Target Group Analysis, you can dive deep into how specific groups score on relevant pathways—think Healthy Aging, Endurance Sport, Skin & Hair Health, and more. For personalized action, InnerBuddies provides nutrition advice derived from 3-day food diaries and stool data, plus tailored probiotics and prebiotics recommendations. If you’re curious about consumer options, you can see our offerings via the InnerBuddies microbiome test. Practical steps to nurture your microbiome—and potentially support mood—include increasing dietary diversity with plant-based fibers, prebiotic-rich foods, and fermented products to encourage a robust microbial ecosystem. Regular physical activity, adequate sleep, and stress management also support a healthier gut-brain axis. With InnerBuddies, you can translate these steps into a personalized plan. For ongoing guidance and structured support, explore the InnerBuddies Gut Health Membership, which complements microbiome testing with ongoing insights, education, and recommendations tailored to your unique gut profile.
