Microbiome and Insomnia: The Surprising Connection That Could Help You Sleep Better

Discover the surprising link between your gut microbiome and insomnia. Growing science points to a bidirectional gut-brain axis where the microbiome can influence sleep quality, ring-fencing your sleep cycles, and how quickly you drift off. When the microbiome shifts—through diet, stress, or illness—it can alter inflammation, serotonin and even melatonin pathways, subtly tweaking the rhythm of your night. By examining the microbiome and insomnia together, you can translate complex biology into practical steps you can take tonight. If you’re curious how your own gut health relates to sleep, you can start by exploring a comprehensive test like the InnerBuddies microbiome test. What sets InnerBuddies apart is a science-backed, modular platform designed to illuminate the microbiome and its links to sleep and beyond. The Gut Microbiome Health Index scores your gut health on a 0–100 scale, grounded in an exclusive IP deal with EAFIT University in Colombia, giving you a clear sense of where you stand. You’ll also see how your abundances of the top 40 bacteria compare to a healthy cohort, and you’ll get categorized insights into bacterial functions, with each function labeled as positive or negative and benchmarked against healthy norms. For deeper personalization, Target Group analysis dives into how the microbiome and its functional pathways relate to topics you care about—whether healthy aging, endurance sport, skin health, or sleep-related considerations—so you can tailor your approach to your lifestyle. The platform also translates measurement into action. Personalized nutrition advice uses your 3-day food diaries and stool data to tailor recommendations for foods that nurture a healthier microbiome and, by extension, better sleep. You’ll receive guidance on which probiotics and prebiotics best align with your objectives and microbiome profile, making it easier to support microbiome and insomnia improvements with a plan that fits your unique gut ecosystem. Start tonight with science-backed steps you can implement now, and then refine them as your microbiome and sleep data evolve. InnerBuddies offers gut test solutions directly to consumers, with all the capabilities available to our B2B partners also accessible to individuals. If you’re exploring ongoing support, the Gut Health Membership provides continuous insights and updates to your personalized plan, while the B2B program invites organizations to power their own gut health products with our white-label Gut Health Operating System.
