Summary
Why Isn't Everyone Talking About Mitochondria? with Jennifer Scheinman Most people learned the word in 10th-grade biology and never thought about it again. That, argues registered dietitian and longevity expert Jennifer Scheinman, is exactly the problem. In this episode of Why Isn't Everyone Doing This?, Emily Fletcher sits down with Jennifer, a nutritionist with over 25 years of experience and a longevity expert at Timeline, the company behind the clinically studied Urolithin A supplement MitoPure, for a conversation that reframes everything from fatigue to aging to consciousness through the lens of your cells. Jennifer explains how the mitochondria work, why their decline accelerates in your 40s and 60s, and what you can actually do to slow that process. They cover the 12 biological hallmarks of aging, the cellular recycling system (mitophagy) that breaks down over time, why so many people can't produce Urolithin A on their own, and how to evaluate supplements in an industry the FDA doesn't fully regulate. They also connect it all to meditation, to stress, to perimenopause, and to the Greek myth of Persephone and the pomegranate. And at the very end: a fact about mitochondrial DNA that changes the way you think about your mother, your grandmother, and the feminine line you carry. In this episode, they explore: – What mitochondria are, what they do, and why they're more like a CEO than a powerhouse – The cellular recycling process (mitophagy) and why it slows with age – Zombie cells, inflammaging, and the 12 hallmarks of biological aging – Why aging isn't linear — and what the research says about the 40s and 60s – How meditation reduces the inflammation driving cellular decline – Urolithin A: what it is, how your gut should be making it, and why most people's isn't –…
