Understanding the microbiome-mental health link helps explain why mood, anxiety, and brain health can shift with changes in gut bacteria. Mounting research suggests gut microbes influence neurotransmitter production, inflammatory pathways, and brain signaling via the vagus nerve, shaping how we feel and respond to stress. Because these processes connect gut health to mental well-being, there are science-backed steps you can take today to support a calmer mood and sharper brain function through the gut. The good news: you can begin making changes now, with data-driven guidance tailored to your unique microbiome. InnerBuddies offers a white-label Gut Health Operating System that powers gut microbiome testing products for companies and consumers alike. It’s a modular platform designed to scale—from assessment and interpretation to personalized action plans. Key features include the Gut Microbiome Health Index (0–100), built on an exclusive IP deal with EAFIT University in Colombia, giving a clear health score for your gut. It also includes Bacteria Abundances for a top 40 community, showing how you compare against a healthy cohort, and Bacteria Functions, where each metabolic role is labeled as positive or negative and benchmarked against a healthy reference. Plus, Target Group analyses dive into how different groups—such as Healthy Aging, Endurance Sport, and Skin & Hair Health—flow through the gut microbiome and functional pathways. On the consumer side, InnerBuddies provides personalized nutrition advice by comparing three-day food diaries with stool data to predict how meals shift the microbiome. The platform hosts a large database that translates individual foods into microbiome outcomes, enabling tailored nutrition guidance and targeted probiotics and prebiotics recommendations that match your objectives and your unique gut profile. Whether you’re assessing a single test or building a full gut-health program for a team, all of these capabilities are accessible through consumer-friendly options as well as enterprise solutions.
