Emily Werner, PhD, RD, CSSD, IFNCP is Team Dietitian for the Philadelphia 76ers (NBA) and Philadelphia Flyers (NHL), and Nutrition Affairs Sport Lead at Timeline. Dr. Emily joins Dr. Mike to unpack postbiotics, urolithin A, and why mitochondrial health matters for pro athletes and everyday people alike, digging into the real research behind Timeline's Mitopure and why chasing $200K gadgets rarely beats getting the fundamentals right. Expect to learn what a postbiotic actually is and how urolithin A differs from other supplements, why old-school and new-school sports dietitians disagree on peptides and supplement fads, how chronic undereating quietly undermines performance in women's sports, what the current human performance research on urolithin A actually shows, how Mitopure is dosed and why urolithin A can't be reliably food-sourced, and why product quality and manufacturing integrity matter more than marketing claims, and much more.
