    The Science of Hormone Metabolism: Fertility, Stress & Personalized Care with Dr. Jaclyn Smeaton

    What if the answers to hormone imbalances, infertility, poor sleep, or unexplained symptoms aren't found in your hormone levels alone, but in how your body processes them?

    In this episode of The DNA Talks Podcast, Dr. Krista Kostroman sits down with Dr. Jaclyn Smeaton, Chief Medical Officer at Precision Analytical, creators of the DUTCH Test, and a leading educator in reproductive endocrinology and fertility medicine. Together, they explore the evolution of hormone testing, the limitations of conventional diagnostics, and how combining genetics, hormone metabolite testing, and functional medicine is changing the future of personalized healthcare. 

    Drawing from her own experience with primary amenorrhea as a teenager, Dr. Smeaton shares the journey that led her into women's health, fertility, and integrative medicine. She discusses how functional testing tools like the DUTCH Test provide a more complete picture of hormone production, metabolism, and detoxification, helping practitioners move beyond symptom management and uncover root causes. 

    The conversation also dives into stress physiology, cortisol patterns, fertility optimization, menopause, genetic individuality, and the promise of AI-powered medicine. Along the way, Dr. Smeaton highlights a powerful truth: optimal health is rarely about choosing between conventional and integrative medicine. It's about choosing the right tool for the right patient at the right time.

    Redefining Aging, Hormones, and Preventive Medicine with Dr. Erika Schwartz

    "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.

    Sex and Longevity: Redefining Aging With Doreen Wendt-Weir

    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.
