What if everything you're doing to stay healthy—your diet, your supplements, your exercise routine—is only part of the story? What if the real question is whether your body is actually absorbing, using, and benefiting at the cellular level? In this powerful solo episode, Dr. Gillian Lockitch invites you to rethink how you measure wellness and healthy aging by introducing a biomarker that is both completely personal and scientifically valid: your antioxidant protection score.Drawing from her background as a physician and specialist medical biochemist, as well as a life-changing personal health scare, Dr. Lockitch explains the invisible but relentless process of oxidative stress—the cellular damage caused by free radicals that accumulates over time and contributes to aging and chronic disease. Through a vivid and emotional story of her sudden diagnosis of myopic macular degeneration, she brings home the reality that aging is not just about time passing, but about what is happening inside your body every single day. This episode goes beyond theory to illuminate the science of antioxidants as your body's essential defense system. You will learn how endogenous antioxidants produced within your cells work in partnership with dietary antioxidants like carotenoids, and why this balance is critical for protecting your brain, eyes, heart, skin, and overall vitality. Dr. Lockitch also explains why nutrient intake alone is not enough—what truly matters is bioavailability, absorption, and delivery to target tissues.Most importantly, this conversation introduces a breakthrough in personalized health: the ability to measure your antioxidant status quickly, non-invasively, and in real time. By tracking carotenoid levels in your skin, with the new Prysm io, you gain a window into your body's internal resilience against oxidative stress. This transforms your approach from guessing and hoping to knowing and acting. If you've ever wondered whether your healthy lifestyle is truly making a difference, this episode will shift your perspective. It is both a call to awareness and a message of empowerment: when you understand what is happening inside your body, you gain the ability to change it—and to take control of how you age, from the inside out.
