So many women feel like their body has suddenly turned against them—weight gain, fatigue, brain fog, and rising inflammation—despite doing all the right things. But this isn’t a failure of effort. It’s a biological inflection point driven by declining estrogen and its impact on metabolism, mitochondria, and vascular health. Together, they break down how estrogen loss reshapes everything from blood sugar control to fat storage, mitochondrial function, and long-term cardiovascular risk—while also exploring the emerging role of gut health and phytoestrogens like S-equol as targeted support. If you’ve been working harder than ever with fewer results, this episode will help you understand why—and what to do instead. Be sure to tune in! SIOBHAN MITCHEL Dr. Siobhan Mitchel, PhD, is a neuroscientist and Chief Scientific Officer at MitoQ. Her work focuses on mitochondrial health, cellular energy, and the role of oxidative stress in aging—particularly in women navigating perimenopause and menopause. She is passionate about advancing research that supports women’s long-term health, metabolism, and resilience at the cellular level. IN THIS EPISODE Why your body stops responding the same way in perimenopause How estrogen loss impacts metabolism, fat storage, and blood sugar The role of mitochondria in energy, brain function, and weight changes Why visceral belly fat increases—and why it’s more dangerous The connection between gut health, estrogen metabolism, and inflammation How phytoestrogens (like S-equol) support metabolism and hormone signaling Why mid… ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/energized-with-dr-mariza-757830/episodes/741-estrogen-gut-health-mitochondria-and-cardiovascular-health-what-changes-in-perimenopause-with-dr-siobhan-mitchel/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/energized-with-dr-mariza-757830/741-estrogen-gut-health-mitochondria-and-cardiovascular-health-what-changes-in-perimenopause-with-dr-siobhan-mitchel.md` — Read the agent-friendly Markdown representation of this episode resource.
