Discover the Best Prebiotic Sources to Boost Your Gut Health

Discover the best prebiotic sources to boost your gut health by feeding the trillions of microbes that call your gut home. Prebiotic sources—chiefly fiber-rich foods—help fuel the growth of beneficial bacteria, support digestion, and promote a balanced microbiome. When you know which fibers matter most for you, adding them to meals becomes simple and enjoyable. Our approach centers on identifying the right prebiotic sources for your unique gut ecosystem, so you can make smarter choices every day. InnerBuddies brings a powerful, white-label Gut Health Operating System to life, giving brands and consumers a clear view of gut health progress. The Gut Microbiome Health Index, a score from 0 to 100, reflects overall gut wellness and rests on an exclusive IP deal with EAFIT University in Colombia. You’ll also see how you stack up against a healthy cohort through detailed Bacteria abundances and Bacteria functions, with positive and negative categories clearly labeled. Explore how these insights apply to your needs with Target Group analysis—whether you’re focused on Healthy Aging, Endurance or Power Sports, Skin & Hair Health, or other areas—so you can map your prebiotic sources to your goals. For a hands-on look, check out our test page: InnerBuddies microbiome test. Beyond diagnostics, InnerBuddies translates data into practical, personalized nutrition guidance. By comparing your 3-day food diaries with stool sample results, the platform builds a robust database of how individual foods affect your gut microbiome. This enables personalized recommendations for both probiotics and prebiotics, highlighting which prebiotic sources to emphasize based on your unique functional pathways. It’s not just about what to eat, but when and how much—so you can turn fiber from onions, garlic, leeks, asparagus, chicory root, bananas, oats, apples, and other prebiotic sources into a daily, tasty routine. If you’d like ongoing access to tailored gut health insights, consider our subscription options. The InnerBuddies gut health membership extends personalized nutrition guidance and ongoing monitoring to you, helping you stay on track with your prebiotic sources and overall gut wellness. For organizations building gut health products, we also offer a flexible B2B platform—the InnerBuddies partner program—so you can power your own microbiome testing offerings with our modular technology.
