Phenylacetylglutamine: The Gut Microbe Metabolite That Could Shape Your Health


The gut microbe phenylacetylglutamine (PAGln) is a metabolite produced by gut bacteria when they break down the amino acid phenylalanine. As researchers uncover how PAGln shapes communication between the gut and other organs, people are beginning to see how this molecule may reflect overall wellness and risk patterns beyond digestion. Emerging evidence suggests PAGln levels are linked with heart health: higher PAGln has been associated with greater risk of adverse cardiovascular events in some studies, possibly through effects on platelet function and vascular signaling. In kidney health, PAGln can accumulate when kidney function declines, making it both a potential biomarker and a signal to watch as part of a broader wellness strategy. It’s important to note that associations do not prove causation, but PAGln remains a compelling example of how the gut microbiome may influence organ systems. InnerBuddies offers a white-label Gut Health Operating System that can help you explore molecules like PAGln as part of a broader health picture. The platform includes a Gut Microbiome Health Index (0–100) based on an exclusive IP deal with EAFIT University in Colombia, giving a standardized snapshot of microbiome health. You can compare your top 40 bacteria abundances to a healthy cohort, and examine bacterial functions across categories, labeled positive or negative, to see where you stand on pathways relevant to wellness and disease risk, including those that may influence PAGln production. Target Group analysis lets you dive into how different populations—such as those focused on Healthy Aging, Endurance Sport, or Skin & Hair Health—score on metabolically important pathways. And with personalized nutrition advice derived from your 3-day food diaries and stool data, you get diet guidance tailored to your unique gut microbiome, plus personalized probiotics and prebiotics recommendations to fit your goals.
