For years, functional medicine has focused on lab results and supplement protocols. Dr. Deanna Minich knows there's a deeper layer most practitioners miss. As a nutrition scientist who worked under Dr. Jeffrey Bland and educated for the Institute for Functional Medicine, she's witnessed how artificial light at night disrupts women's hormones more than almost any other factor, yet it's completely ignored.
In this episode, Dr. Minich reveals why 85% of people are Omega-3 deficient despite supplementing, how eating a rainbow of 30+ plant species weekly rebuilds your microbiome diversity, and why your skin's "photo-metabolome" produces healing compounds from sunlight that Vitamin D pills can never provide. She explains the Goldilocks principle of sun exposure, why most women only get 11-15 grams of fiber daily when they need triple that, and how stress functions as a toxin that triggers leaky gut and impairs detoxification. Dr. Minich also shares why women's heightened sensitivity isn't a weakness but a powerful gift for intuition and healing.
If you're tired of functional medicine that stops at labs and supplements, this conversation offers a comprehensive framework integrating circadian optimization, creative expression, gut diversity, and the spiritual aspects of women's health that determine true longevity.Guest’s socials + website

Most people think heart disease is just about cholesterol. But what if the real issue is in your genes, your environment, and even your daily stress?
In this episode, I’m joined by Dr. Christopher Davis, a triple board-certified interventional cardiologist who’s redefining what it means to take care of your heart. After years of performing stent procedures, he realized the conventional system was only treating symptoms, not causes. So he made a bold shift from reactive cardiology to a root-cause approach that blends advanced testing, functional medicine, detoxification, and even ancient healing wisdom. We discuss how genetics determine whether saturated fats help or harm you, why cholesterol itself isn’t the enemy, and how inflammation and oxidative stress are the real threats to your arteries.
If you’ve ever wondered why someone with perfect cholesterol can still have a heart attack, or why your stress levels matter just as much as your diet, this conversation will change how you think about cardiovascular health forever.

Dr. Brad Schoenfeld, PhD is one of the world’s leading researchers on muscle hypertrophy (muscle growth). He is a Professor of Exercise Science at Lehman College in New York, where he directs the Human Performance Laboratory. Over his career, he has published more than 300 peer-reviewed articles, book chapters, and textbooks on resistance training, body composition, and nutrition.
He is the author of Science and Development of Muscle Hypertrophy and The Max Muscle Plan, and has received prestigious honors such as the NSCA Young Investigator of the Year and the Dwight D. Eisenhower Fitness Award. Beyond academia, he has been a personal trainer and natural bodybuilding competitor, which allows him to uniquely bridge cutting-edge science with practical application.
Here's what he knows: the fitness industry has been selling you the wrong story. Not maliciously, but confidently. And most people are paying the price without even realizing it.
In this episode, Brad reveals why so many people are working harder than they need to while missing the basics that matter most. We discuss the beliefs keeping women from reaching their potential, the risks that sneak up when you avoid certain types of training, and what actually determines whether you stay strong and independent decades from now. He also tackles the myths around supplements, workout structure, and whether you're doing enough or too much.
If you're ready to stop spinning your wheels and start training smarter, this conversation will show you exactly where to begin.

Today I’m joined by Dr. Lara Briden, a naturopathic doctor, best-selling author, and internationally recognized expert in women’s hormones for a wide-ranging conversation on cycle health and why ovulation is a vital sign of wellbeing.
We talked about how monthly ovulation creates hormones that support bones, metabolism, and brain function, and what happens when that rhythm is disrupted by stress, restrictive eating, or birth control. Dr. Briden explains why natural estradiol and progesterone are so protective, how they differ from synthetic hormones, and what that means for both younger women and women approaching perimenopause.
She also shares her perspective on missing periods, hypothalamic amenorrhea, and the four functional types of PCOS, along with the growing role of insulin resistance in hormone imbalance. We talk about how to track ovulation, what lab markers to look for, and why restoring cycles is one of the most powerful steps for long-term health.

What if aging wasn’t just something that happens to us, but something science could actually slow down? That’s the question at the heart of today’s conversation with Dr. Matt Kaeberlein, who’s a leading scientist and longevity researcher at the University of Washington.
Dr. Kaeberlein has spent decades decoding the biology of aging, from cellular mechanisms to practical strategies that could extend not just how long we live, but how well we live. In this episode, we talked about surprising connections between aging and brain health, and looked into the research around lithium and Alzheimer’s to see what the latest science is telling us about extending healthspan.
It is an informative discussion on whether aging itself can be slowed or reversed. If you’re curious about how close we really are to changing the rules of aging, this could be worth a watch.
