What if the reason you feel more tired, foggy, or just not like yourself anymore… isn’t just hormones or “getting older” — but something happening deeper in your body? In this episode, I sit down with Jen Scheinman, a registered dietitian with over 25 years of experience in nutrition and healthy aging and Director of Science Communications at Timeline Nutrition. Jen is one of the leading educators on Urolithin A — a postbiotic compound found in Mitopure — and its role in mitochondrial health, cellular renewal, and longevity. Beyond Timeline, she also runs her own practice, Next Jen Health, where she helps women optimize vitality through the menopause transition and beyond. We explore a part of our health that most of us have never really been taught to think about—our mitochondria, the energy centers inside our cells — and why so many women start to feel a shift in their 30s and 40s, when the things that used to work suddenly don’t. Jen breaks down the science in a way that actually makes sense, connecting fatigue, brain fog, and changes in your body to what’s happening at the cellular level. We talk about why diet and exercise can stop working the way they used to, how your gut and environment impact your energy, and what’s really going on beneath the surface as we age. We also explore the difference between living longer and actually feeling good while you do it — and what it looks like to support your body in a way that aligns with how it truly works. This conversation isn’t about quick fixes. It’s about understanding your body on a deeper level so you can start to feel like yourself again. Mitopure now starts at just $79.
