Today, Dr. Sara and longevity expert Kayla Barnes-Lentz dive deep into the emerging science of microplastics, detox pathways, and personalized medicine. Drawing from Kayla’s recent lab work—which included elevated BPA (bisphenol A) levels and genetic vulnerabilities—they explore how chronic exposure to environmental toxins affects hormones, inflammation, and long-term health. Together, they discuss how to interpret genomics like the 3x4 panel, why methylation and inflammation matter for women’s health, and what proactive steps can be taken to reduce toxic load—from cod liver oil and cruciferous vegetables to advanced biomarker testing. This conversation is the first of many focused on data-driven protocols for female optimization—rooted in science and grounded in lived experience.
