Why You Feel Depleted: Oz Garcia on Healthspan & Brain Vitality - Episode 149

Most people obsess over lifespan—but what if the real metric that matters is healthspan? In this powerful conversation, Dr. JC Doornick sits down with world-renowned longevity expert Oz Garcia to unpack why so many people feel depleted, foggy, and biologically older than their years—even when their labs say they’re “fine.” From post-COVID fatigue and chronic inflammation to mitochondrial health, cellular energy, brain vitality, and the responsible use of peptides as signaling molecules, this episode dives deep into what actually drives aging—and how to reverse the biological drift. If you’ve been asking, “Why am I always tired?” or wondering how to stay sharp, resilient, and fully alive after 40 or 50, this conversation will reframe everything you thought you knew about longevity. This isn’t about hacks. It’s about protecting your energy, preserving your brain, and staying in the game for decades to come.
