Support your family’s health this season with Richmond Integrative & Functional Medicine’s Back-to-School 2026 resources. Back-to-School 2026: https://richmondfunctionalmedicine.com/lp/back-to-school-2026/ What if healthy aging is influenced not only by the number of birthdays you’ve celebrated, but also by the ecosystem living inside your gut? In this insightful episode of Made for Health, Dr. Aaron Hartman sits down with Dr. Julia Malkowski, ND, DC, a naturopathic doctor, doctor of chiropractic medicine, and clinical educator at Doctor’s Data whose work focuses on the gut microbiome and functional diagnostics. Dr. Malkowski’s path into medicine began with a deeply personal experience. When her infant son developed a persistent skin rash, she sought answers beyond the explanations she had been given. She shares how seeing his skin improve after a dietary change redirected her career and inspired her to pursue naturopathic medicine. Today, that same curiosity shapes her work exploring “biome aging”—the idea that changes in the gut microbiome may offer insight into biological aging and health across the lifespan. Together, she and Dr. Hartman discuss microbiome diversity, inflammation, estrogen metabolism, perimenopause, menopause, GLP-1 medications, intestinal barrier function, and the influence of food and environmental exposures. The conversation ultimately returns to a practical message: supporting gut health begins with everyday foundations. From greens, beans, and berries to movement and time outdoors, Dr. Malkowski shares the habits she prioritizes before reaching for more complex interventions.
