Microbiome Aging: How Your Gut Microbes Change Over Time—and How to Support Them

Microbiome aging describes how your gut's microbial community evolves as you age, altering diversity, metabolism, and immune interactions. With advancing years, some microbial groups can become less diverse while others shift in function, which may influence digestion, energy, and resilience to illness. Yet these changes aren’t fate—diet, sleep, stress, and activity can modulate microbiome aging in meaningful ways. By understanding how your gut microbes tend to evolve over time, you can adopt simple, science-backed habits to support a healthier microbiome today. Tracking these shifts provides a practical roadmap for improving gut health across the lifespan. InnerBuddies offers a white-label Gut Health Operating System that brands can use to power microbiome testing products and deliver real, actionable results. The platform’s Gut Microbiome Health Index scores your gut health on a 0–100 scale, based on an exclusive IP deal with EAFIT University in Colombia. It also presents Bacteria Abundances from a Top 40 panel, showing how you compare against a healthy cohort for both beneficial and potentially harmful microbes. The Bacteria Functions map groups metabolic activities into positive and negative categories, letting you see where your microbiome supports or hinders key pathways relevant to aging. With Target Group Analysis, you can zoom in on microbiome aging-related topics such as Healthy Aging, as well as performance, skin health, and more. Personalized nutrition and lifestyle guidance flow from the platform, leveraging data from 3-day food diaries matched with stool samples to predict how foods influence your gut microbiome and to tailor recommendations to your unique composition. Likewise, personalized probiotics and prebiotics guidance suggests strains and dosages aligned with your objectives and your microbiome aging profile. InnerBuddies also provides consumer-ready gut test solutions, so individuals can access robust insights directly. For businesses, the modular platform scales from individual tests to full product ecosystems, delivering the same powerful analytics that powers B2B partnerships. Ready to start?
