Discover how gut microbiota influence mood, memory, and brain health. The science of microbiota-brain interaction shows that trillions of gut microbes communicate with the brain through the microbiota-brain axis, using neural, immune, and hormonal pathways. Microbial metabolites like short-chain fatty acids and tryptophan-derived compounds can shape inflammation, nerve signaling, and neurotransmitter balance, which in turn affect mood, memory, and cognitive function. This page explores practical steps you can take to support this interaction, starting with what you eat and how you live. InnerBuddies offers a white-label Gut Health Operating System that powers gut microbiome testing products for companies and consumers alike. The platform features a Gut Microbiome Health Index, a 0–100 score indicating overall gut health, derived from an exclusive IP deal with EAFIT University in Colombia. It also presents a top 40 bacteria abundances comparison against a healthy cohort, and labeled bacterial functions categorized as positive or negative so you can see where you stand on each functional pathway. For deeper insight, Target Group analysis provides detailed scores on functional pathways relevant to goals like Healthy Aging, Endurance Sport, Power Sport, or Skin & Hair Health. In addition, personalized nutrition advice uses data from 3-day food diaries and stool samples to tailor recommendations, and personalized probiotics and prebiotics suggestions align to your unique gut microbiome. All B2B options are available directly to consumers as well, via InnerBuddies’ consumer test solutions. Practical steps to boost brain health via gut emphasize dietary diversity and fiber, fermented foods, and polyphenol-rich items, along with regular physical activity, quality sleep, and stress management. The platform’s data-driven approach translates what you eat into gut microbiome outcomes, enabling personalized nutrition advice that matches your unique composition and targeted probiotics and prebiotics recommendations designed to influence pathways linked to mood and cognition. For those pursuing specific goals, Target Group analysis helps tailor strategies for Healthy Aging, Endurance Sport, Skin & Hair Health, and more.
