Episode 42: SPONSORED Unlocking the potential of endocannabinoid system w Dr. Jacqueline Jacques
Yes, hemp & marijuana are major providers of cannabinoids, and in the FxMed space, we are extremely excited about this potent family of bioactive molecules. In particular, we are looking at CBD for indications ranging from pain to mood, inflammation, memory and more. Turns out the endocannabinoid system (ECS) extends body-wide, and similarly, phytocannabinoid sources extend far beyond hemp and marijuana. Listen to my conversation with Dr. Jacqueline Jacques, Senior VP with THORNE – and tour the ECS and the use of phytocannabinoids from hemp, rosemary, clove, black pepper and even hops, whose constituents have an “entourage” effect on the ECS, along with other commonly prescribed compounds including diindolylmethane, ginseng, echinacea. It strikes me as extremely logical we’d be thinking about using phytocannabanoids with most of our patients and ourselves – probably PCs are foundational interventions not dissimilar to the regularly prescribed essential fatty acids. We get the inside scoop on all this and more in New Frontiers! Take a listen and let me know what you think:

Episode 41: Food: What the Heck Should We Eat with Expert Dr. Mark Hyman
In my conversation with Mark Hyman on his new NYT best seller, Food: What the Heck Should I Eat?, we discuss the myriad challenges consumers face in figuring out the correct diet, but also, what WE as clinicians caring for patients – what do we prescribe? What do the data show? Are grains really verboten? Is dairy completely off-the-plate? What about meat? And fats/cholesterol and the APOE4 patient? Mark enlightens me to the new “regenerative agriculture” movement; going far beyond organic, regenerative agriculture regenerates the environment while providing good, clean food. Amazing, right? He also addresses the common price complaint. What is the cost of eating clean vs eating conventional? We also go behind the scenes to address the insidious agribusiness at the heart of US policy, and chat about Steven Savage’s recent take-down of Environmental Working Group’s Dirty Dozen Clean Fifteen lists. This was such a fun convo for me, and as always, Mark is doing great detective work getting to the heart of concerns around diet and the ecology of eating. Take a listen, I bet you’ll be as intrigued as I was.

Episode 40: The Epicenter of Epigenetics; Discussing the Agouti Mice Study with Dr. Randy Jirtle
I am thrilled and honored to podcast with Dr. Randy Jirtle. The field of epigenetics has exploded in the last decade, initiated almost exclusively by the groundbreaking research of Randy and his colleague Robert Waterland. Their 2003 study on the effects of nutrition on epigenetic gene regulation in agouti mice is the most cited paper in the history of science, and his trailblazing discoveries have expanded our understanding of human health and the etiology of disease. Listen to my fascinating conversation with Dr. Randy Jirtle.

Episode 39: SPONSORED: Scientific Serendipity: Beautiful Bio-Botanicals with Dr. Rachel Fresco
A lot of scientific discoveries are borne out of serendipitous moments where a brilliant idea and unmet need collide. Such is the case with one of my all-time favorite “workhorse” botanical combination products, Biocidin. Listen to Dr. Rachel Fresco, founder and president of Bio-Botanical Research, talk about the story of Biocidin, the decades of interesting and on-going in-vivo and in-vitro research, and loads of clinical reports demonstrating efficacy. Also hear about Bio-Botanical’s suite of other no less creative products, including Oliverex, Proflora4R and GI Detox.
In my practice, Biocidin is a work horse botanical combination I use ALL the time. It’s well-tolerated, and being a liquid formulation, I can dose low and slow or high and aggressively as I need to. Listen to my conversation with Dr. Rachel Fresco here!

Episode 38: SPONSORED HPA, Organic Acids and the DUTCH Test with Dr. Carrie Jones
Why would Precision Analytical, the laboratory famous for the ground-breaking DUTCH test (Dried Urine Test for Comprehensive Hormones) and Cortisol Awakening Response test, decide to offer a handful of key organic acids on their panel (incidentally, at no extra charge)? The answers will wow you in this terrific podcast with Dr. Carrie Jones, Medical Director at PA. Turns out, looking at compounds such as homovanillic acid, vanillmadilic acid, 5HIAA, pyroglutamate, 8OH2DG and xanthurenate have LOADS to do with our sex hormones and our HPA axis at many different levels. As usual, Dr. Jones provides fun analogies (how does a trampoline explain perimenopause?), clinically useful information on test interpretation and on intervention considerations. Don’t miss it.

Episode 37: The Gut/Thyroid Connection with Dr. Michael Ruscio
Join me for an interesting, clinician-friendly conversation on the gut/thyroid axis with Dr. Mike Ruscio. Dr. Ruscio challenges both conventional understanding (where the gut/thyroid relationship isn’t recognized outside the research setting) and in the functional medicine world, where he argues we are often over-treating and over-testing thyroid function. What is the thyroid adrenal relationship? What should we expect with regard to thyroid antibodies and successful treatment? What should we be thinking about with regard to gut health when diagnosing and treating thyroid disease? Listen to this great New Frontiers episode where we dive deep into all this and more!

Episode 36: Changing the World with Unconventional Medicine – A Conversation with Chris Kresser
When Chris Kresser, M.S., L.Ac, was in his early twenties, he traveled the world surfing and learning to meditate. Along the way, he fell ill — and when he returned to the States he discovered that the conventional medical paradigm had little to offer when it came to treating complex, chronic illness. So he embarked on his own healing journey, studying acupuncture and Chinese medicine and learning about ancestral health. Today he is a globally recognized leader in the fields of functional and integrative medicine. In this podcast, he talks with Dr. Fitzgerald about being one of the first holistic practitioners to establish a solid online presence; why blogging and writing about functional, ancestral, and integrative approaches to health matter today more than ever; and how the current medical paradigm needs to be reinvented both to prevent and reverse chronic disease and to prevent the collapse of the entire healthcare system. His new book Unconventional Medicine is available now.

Episode 35: SPONSORED: Dr. Kenneth Brown / Atrantil
Small-intestinal bacterial overgrowth, or SIBO, is notoriously hard to treat. Patients often experience persistent bloating—and even when they find relief, symptoms can return months later, seemingly out of the blue. After struggling to help patients feel better using the tools of conventional gastroenterology, Dr. Ken Brown began to research compounds that could effectively treat SIBO-related bloating. The result of his work is Atrantil, the only all-natural formulation for treating SIBO-related bloating. In this podcast, Dr. Fitzgerald talks to Dr. Brown about dosing and treating patients with Atrantil, when to run further tests, and what other treatments can be used in conjunction with Atrantil to get the best results.

Episode 34: Miracle Mind, Warrior Heart: A conversation with JJ Virgin
JJ Virgin was a well-known fitness and nutrition expert and author of several books when her son was hit by a car and severely injured. The doctors told her to prepare for the worst; they didn’t expect him to make it through the night. But, Grant lived. And JJ’s insistence on making sure he had access to both conventional and functional medical care is the reason why. She became an expert on the essential interventions for severe traumatic brain injury and insisted on their use during his recovery. In this podcast, the four-time New York Times bestselling author tells the story of her son’s accident and recovery, talks about her newest book, Miracle Mindset, and shares amazing clinical pearls on treating traumatic brain injury with functional interventions.
In this podcast, you’ll hear
JJ’s list of essential interventions for severe traumatic brain injury, including
CBD oil with omega 3’s
Essential oils, lavender combination (find details at www.grantvirgin.com)
Autologous stem cell therapy (stem cell revolution)
Progesterone/hormone balancing
Prayer
Diet
Very high dose omega-3 fatty acids (up to 20 grams)
Amino acids (higher dose branched-chain amino acids to prevent catabolism)
Hyperbaric oxygen therapy
The power of mindset
Avoiding hospital food

Episode 33: SPONSORED: Further Down the Elemental Diet Road with Dr. Corey Schuler
Elemental Diets have a long therapeutic use history for myriad GI issues. EDs allow the gut to take a break from the hard work of digestion, offering the GI tract a chance for renewal and repair. They have been shown to help with a variety of conditions, including SIBO, IBS, non-specific intestinal inflammation, and autoimmunity, including IBD (among others). In this podcast, the director of clinical affairs for Integrative Therapeutics, Dr. Corey Schuler, answers some of the most frequently asked questions about using the Elemental Diet with patients, from how to use it while simultaneously treating other conditions (like fungal overgrowth or severe vitamin D deficiency) to creative ways to help patients stick to a challenging eating protocol.
