"Your doctor doesn't live inside your body. AI doesn't live in your body. Influencers don't live in your body. Only you live there."

What if the future of medicine isn't about treating disease, but empowering people to take ownership of their health long before illness appears?

In this compelling conversation, Dr. Lara Varden sits down with renowned physician, author, and longevity expert Dr. Erika Schwartz to discuss a lifetime spent challenging conventional medicine and advocating for personalized, preventive healthcare.

Dr. Schwartz is a board-certified internist, entrepreneur, best-selling author, and nationally recognized leader in hormone health and longevity medicine. For more than three decades, she has championed personalized, preventive care — long before it became mainstream. 

She is the founder of Evolved Science and ESHealth, where she has been a pioneer in the use of bioidentical hormone therapy, focusing on restoring vitality, optimizing healthspan, and redefining how we approach aging. 

Dr. Schwartz has authored eight best-selling books, including The Hormone Solution and The Intimacy Solution, helping bring conversations about hormone balance and quality of life into the medical mainstream. Her work has appeared in major publications such as The New York Times, The Wall Street Journal, Vogue, Town & Country, and The New York Post, and she is a frequent media contributor across television and international podcasts. 

She is also a distinguished faculty member of A4M — the world’s leading longevity and functional medicine organization — where she hosts the widely followed Redefining Medicine podcast. 

Drawing from more than 40 years of clinical experience, Dr. Schwartz shares her journey from emergency medicine physician to one of the earliest pioneers of hormone optimization, functional medicine, and healthy aging. She explores why modern healthcare often focuses on disease instead of wellness, the truth about hormone replacement therapy, the importance of patient empowerment, and how genetics can help personalize health decisions.

Tune in and realize how longevity isn't just about living longer, it's about living better.

What if the biggest lie you’ve ever been told about your health is that your brain is destined to decline?

Justin Harris is joined by Dr. Tommy Wood, who currently works as an Associate Professor of Pediatrics and Neuroscience at the University of Washington, where my laboratory focuses on brain health across the lifespan — conducting research that focuses on ways to treat a range of brain injuries. This includes babies born preterm, adults who experience brain trauma, and the confluence of factors that can affect long-term cognitive function and risk of dementia.

​Dr. Tommy Wood received a Bachelor’s degree in biochemistry from the University of Cambridge, a medical degree from the University of Oxford, and a PhD in Physiology and Neuroscience from the University of Oslo. He has published dozens of scientific papers and lectured all over the world about brain health, metabolism, physical activity, and human performance. Dr. Tommy also spent more than a decade working as a performance consultant to professional athletes in multiple sports including several Olympians and world champions. 

In this episode, we dive into one of the most important conversations in modern health: how to protect, strengthen, and future-proof your brain. Dr. Tommy Wood breaks down why cognitive decline is not inevitable and how your daily choices, your epigenetic inputs, play a powerful role in shaping brain health across your entire lifespan.

From neuroplasticity and skill-building to sleep, social connection, and metabolic health, this episode delivers a practical, science-backed blueprint for long-term cognitive performance.

What if your sex life was one of the most powerful drivers of longevity?

In this episode, Dr. Tracey Steady Hardcastle is joined by intimacy expert Susan Bratton to explore the science-backed connection between sex and longevity, and why she calls it the missing pillar of health.

Together, they unpack the concept of ageless intimacy - how pleasure, connection, and “orgasmic intimacy” support everything from blood flow and hormones to nervous system regulation and emotional resilience.

This conversation reframes intimacy not as a luxury, but as a biological necessity for living a longer, healthier, and more vibrant life.

What if everything you believed about aging was incomplete?

In this engaging and refreshingly honest episode of The DNA Talks Podcast, we welcome Doreen Wendt-Weir, author of Sex in Your Seventies and its spirited sequel, Gardening in Your Nineties.

Doreen challenges cultural narratives around aging by asking bold, often humorous questions about vitality, intimacy, creativity, and identity later in life. Through her writing—and this conversation—she invites listeners to rethink what it means to grow older with curiosity, connection, and self-respect.

We talk about why conversations around aging are so often avoided, how humor and honesty can open doors to deeper understanding, and why it’s never too late to redefine joy, purpose, and personal expression. Doreen’s perspective is both practical and playful, offering a counter-narrative to age-based limitations and assumptions.

This episode is a celebration of longevity, lived experience, and the freedom that can come with embracing each stage of life on your own terms.

If the body is designed to heal, what happens when we finally create the conditions that allow it to do so?

In this deeply moving and empowering episode of The DNA Talks Podcast, Dr. Tracey Steady‑Hardcastle sits down with Dr. Zelina Medina, founder of Acuvida Acupuncture, to explore the powerful intersections of autoimmune disease, trauma, nervous system regulation, functional genomics, and root‑cause healing.

Diagnosed with lupus and kidney failure in her twenties, Dr. Medina shares her personal healing journey - one that led her beyond symptom management and into a holistic, integrative approach that blends science, Chinese medicine, lifestyle medicine, and spiritual healing. Now symptom‑free for over a decade, she helps patients heal chronic illness by addressing nervous system safety, unresolved trauma, inflammation, and individualized constitutional needs.

Together, Dr. Steady and Dr. Medina discuss how trauma becomes stored in the body, how genetics influence stress and inflammation responses, and why true healing requires addressing mind, body, and spirit.

In this deeply honest and empowering episode of The DNA Talks Podcast, Dr. Tracey Steady-Hardcastle sits down with Dr. Lisa Olszewski, chiropractor, naturopath, founder of the American Institute of Healthy Living, and host of Healthy Living Simple with Dr. Lisa.

Dr. Lisa shares her personal health crisis—despite “doing everything right”—and how it reshaped her approach to nutrition, women’s hormones, ketogenic diets, intermittent fasting, and true wellness. This conversation explores why one-size-fits-all health advice fails, how women’s bodies differ biologically from men’s, and why listening to your body and your genetics matters more than following trends.

If you’ve ever wondered why keto, fasting, or intense exercise worked for everyone else but left you exhausted, stuck, or unwell - this episode is for you. Here are the highlights of this episode:

• Why women cannot follow keto or fasting protocols the same way men do
• How prolonged ketosis and extreme fasting can impair thyroid, adrenal, and reproductive health
• What strategic carb cycling looks like for cycling vs. postmenopausal women
• Common intermittent fasting mistakes that stall progress or worsen symptoms
• How chiropractic care impacts hormones, metabolism, and digestion
• Why symptoms are warning signals—not problems to suppress
• How to simplify healthy living without perfection or burnout

The immune system plays a central role in how we age—but what if we could train it to work better over time?

In this episode of The DNA Talks Podcast, Dr. Lara Varden welcomes Dr. Chris D’Adamo, PhD, epidemiologist and integrative medicine researcher, for an in‑depth conversation on beta‑glucans, trained immunity, and longevity‑focused health strategies.

The discussion also explores:

• Immune health and its link to aging, mood, and chronic disease
• The gut‑brain‑immune connection
• Stress, recovery, and immune resilience
• Clinical insights on respiratory infections, autoimmunity, and detoxification
• How genetics and lifestyle together shape immune response

With insights drawn from decades of research and recent clinical trial data, this episode offers a practical and empowering look at how immune optimization fits into precision, functional, and longevity medicine.
