    The Flawed Prophet Behind Today's Psychedelic Boom | John O'Connor

    Did today's psychedelic therapy boom start with a man who liked to make things up? On The Dr. K Show, Dr. K talks with John O'Connor, journalist and author of A Short, Strange Trip, about Terence McKenna and the 1971 magic mushroom and ayahuasca experiment in the Colombian Amazon that shaped how we think about psychedelics. O'Connor, who retraced the trip himself, explains what the McKenna brothers were really chasing and why he thinks psychedelics can help with PTSD and addiction without being a magic bullet. If you're curious about psychedelic therapy, or wary of the hype, start here. Key Takeaways: Terence McKenna's La Chorrera experiment and the psychedelic renaissancePsychedelic therapy for PTSD and addiction, and why it isn't a magic bulletMagic mushrooms, ayahuasca and grief: what the McKenna brothers were chasingAyahuasca, tobacco and coca: how Amazon shamans actually use themSchedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: A Short, Strange Trip: An Untold Story of Magic Mushrooms, Madness, and a Search for the Meaning of Life in the Amazon - https://a.co/d/0e0B616u John O'Connor - https://www.johnmoconnor.com/ True Hallucinations by Terence McKenna https://a.co/d/0dEV6eA2 Food of the Gods by Terence McKenna https://a.co/d/0g548Lr6 Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Joe Sheehey | Why Full Spectrum CBD and THC Could Become Illegal Nationwide on November 12

    What if the CBD or THC product that finally gives your child relief from seizures, or gives you a real night of sleep, becomes illegal in a few months, because of a sentence quietly added to a bill about reopening the government? In this episode of The Dr. K Show, Dr. K sits down with Joe Sheehey, founder and CEO of Cured Nutrition, about the fight to keep full spectrum hemp extract legal in the United States. Joe spent years as an aerospace engineer contracted to NASA through Lockheed Martin, until a mental health crisis in college and a later moment of shame over using CBD at a federally funded company pushed him to leave engineering and build a company around changing the conversation on cannabinoids. They cover the hemp definition change buried in the bill that reopened the government, the research behind a non-impairing THC dose, and the story of Charlotte Figi, whose family's use of full spectrum hemp extract for epilepsy helped start the entire industry. If you've wondered whether cannabinoids are safe, or you're watching access to them disappear state by state, this conversation lays out what's at stake. Key Takeaways: Why full spectrum CBD and THC products are set to become illegal nationwide on November 12, 2026, after a hemp definition change was folded into the bill that reopened the governmentThe Johns Hopkins research behind the 3 milligram non-impairing THC threshold, and why Cured Nutrition caps its products at 1.25 milligrams per servingCharlotte Figi, the 20 to 1 CBD to THC ratio, and how one family's use of full spectrum hemp extract for epilepsy became the foundation of the entire CBD industryFrom NASA-contracted aerospace engineer to CBD founder: Joe Sheehey on the mental health crisis and workplace shame that pushed him to start Cured NutritionWhy combining CBD with THC may help cancer patients avoid the opioid spiral of pain, lost appetite, and constipationSchedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: Cured Nutrition - https://curednutrition.com  Serenity Gummies - https://curednutrition.com/products/serenity-gummies  One Hemp - https://onehemp.us  Coalition for Access Now - https://www.coalitionforaccess.org  Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Jeff Nuziard | Erectile Dysfunction, Testosterone Therapy and the RegenMax Protocol

    Why does losing sexual function make so many men ask themselves the same question: am I enough? In this episode of The Dr. K Show, Dr. K sits down with Jeff Nuziard, founder of RegenMax and a specialist in hormone optimization and erectile dysfunction reversal, about the moment his own body stopped working the way he expected it to. At 40, Jeff's testosterone had dropped from 1185 to 305 with no real change in his lifestyle, and the erectile dysfunction that followed sent him into a research process that has now spanned more than twenty years and treated over 3,200 patients. They talk about what actually happens inside the body during an erection, why the corpus cavernosum breaks down the same way a kitchen sponge does over time, and how RegenMax combines hormone optimization, collagen remodeling and a placenta-derived biologic to reverse erectile dysfunction in a reported 97 percent of cases, without relying on pills alone. Jeff also shares a statistic that stopped Dr. K cold: erectile dysfunction is now the third leading cause of suicide among men. If you or someone you love has quietly wondered whether this is just something to live with, this conversation says otherwise. Key Takeaways: Why erectile dysfunction is tied to a man's sense of identity, and its link to being the third leading cause of suicide among menThe real cause of erectile dysfunction: how the corpus cavernosum and a "venous leak" explain why men can get erect but can't maintain itWhy testosterone loss, not aging itself, is what activates the aging process, and how levels can fall from 1185 to 305 in about a decadeInside RegenMax: how collagen remodeling, angiogenesis and a placenta-derived biologic reverse erectile dysfunction in a reported 97 percent of casesWhy pelleted testosterone replacement, not injectable, is the more consistent way to keep hormone levels stable long termSchedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: RegenMax - https://regenmax.com  Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Dana Kay | ADHD, Four Medications at Five, and What Was Really Driving It

    What do you do when your five-year-old is already on three medications, and the doctor wants to add a fourth? In this episode of The Dr. K Show, Dr. K sits down with Dana Kay, founder of the ADHD Thrive Institute and author of Thriving with ADHD, about the medication spiral that sent her from accounting into functional medicine, and the moment in a doctor's office that changed her family's course. Dana Kay walks through her theory that most ADHD symptoms trace back to an overloaded body rather than a fixed brain disorder, covering gluten, gut health, and the testing she uses to find what's really driving a child's symptoms. If your child's diagnosis has felt like the end of the conversation instead of the start of one, this episode gives you somewhere else to look. Key Takeaways: Why ADHD diagnoses in children keep climbing, and why Dana Kay believes more than 70 percent of the kids she works with do not have true ADHDInside the medication spiral: how her son ended up on four ADHD medications by age five, and what the stimulant and SSRI side effects actually looked likeThe "trash can" theory of ADHD: how chronic inflammation, toxin overload and gut dysfunction drive ADHD symptoms in childrenGluten, glutamorphin and ADHD: how a gluten peptide that acts like morphine in the brain fuels meltdowns, anxiety and mood swingsWhy girls get diagnosed with ADHD later than boys, and how inattentive ADHD symptoms get missed at school and at homeSchedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: ADHD Thrive Institute - https://adhdthriveinstitute.com  Thriving with ADHD - https://www.goodreads.com/book/show/61281966-thriving-with-adhd Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Dr. Julie Merriman | Are We Gonna Have Sex or What? Reclaiming Desire After 50

    What does it mean when a woman in her fifties says her life force has just leaked out? In this episode of The Dr. K Show, Dr. K sits down with Dr. Julie Merriman, a licensed professional counselor supervisor, yoga therapist, and university professor whose new book carries a title that turns heads: Are We Gonna Have Sex or What? Dr. Merriman has watched her clients age alongside her over the years, and around fifty she started hearing the same thing over and over from the women in her practice: something felt gone, and they assumed they were broken. Her research pointed her toward the nervous system, and toward a pattern she believes gets missed in most conversations about hormones and menopause: a woman can be on hormone replacement and still not feel desire come back online if her body has spent thirty years bracing for the next item on the to-do list. They talk about why so many women hit fifty with a nervous system that has been running on fight or flight for decades, why hormone replacement alone often is not the full answer, and why Dr. Merriman believes an earth shattering orgasm might be one of the best resets available for a body that has forgotten how to soften. She also shares how she and her husband have kept their own forty-year marriage playful, and why respect, communication, and a little novelty matter as much as anything that happens in the bedroom. If you have ever felt like you have been carrying everyone else's needs for so long that you forgot where your own body finds pleasure, this conversation is for you. Key Takeaways: 0:00 Introduction 0:27 The story behind "Are We Gonna Have Sex or What?" 0:59 Why the women in her practice felt their life force draining 6:59 Thirty years in fight or flight, and why the nervous system goes numb by fifty 15:02 Unlearning that heavy emotions were never okay to feel 19:26 Why hormone replacement alone does not bring desire back online 24:11 Sex as the best reset for a dysregulated nervous system 29:32 Respect, communication and keeping a forty-year marriage alive  Schedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: Are We Gonna Have Sex or What? - https://www.amazon.com/Are-Gonna-Have-Sex-What-ebook/dp/B0GHZCYSKZ Sexy After 50 (Dr. Julie Merriman's podcast) - https://podcasts.apple.com/us/podcast/sexy-after-50-improve-sex-intimacy-by-healing-your/id1865726696 Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Rush Simonson | Juvent, Micro-Impact Therapy and Reversing Osteoporosis Naturally

    What if the fastest way to protect your bones has nothing to do with a pill, and everything to do with the way your heel hits the ground? In this episode of The Dr. K Show, Dr. K sits down with Rush Simonson, a former Medtronic spinal implant distributor who spent eighteen years inside more than a thousand spinal surgeries before turning to molecular medicine, where he co-discovered a novel protein complex behind chronic back and joint pain now in FDA Phase 2 trials. Simonson walks through mechanotransduction, the process by which the simple impact of a footstep signals the skeleton to rebuild itself, and how his company built the microimpact device Juvent around that discovery. They get into why cushioned running shoes can work against your bones, why a proton pump inhibitor prescribed for heartburn can quietly starve the body of calcium, and why more stimulation isn't always better; Simonson's own protocol is just ten to twenty minutes a day. He also shares what he's seeing in Parkinson's patients using microimpact for lymphatic drainage, and why physician-guided bone density programs are seeing gains of three to six percent a year. If you've ever been told your bone density will only keep declining, this conversation makes the case that it doesn't have to. Key Takeaways: 0:00 Introduction 0:30 From spinal implant surgeries to discovering the protein behind chronic back and joint pain 11:35 "If you lie, you die": why constant motion drives cellular repair 17:17 Olympic swimmers with osteopenia, and why osteoporosis often starts in the teen years 25:11 Unexpected results in Parkinson's patients: microimpact and the brain's lymphatic system 28:30 The right dose: ten to twenty minutes a day, and why more isn't better 31:40 Panic attacks, arrhythmias and restless legs: the hidden signs of calcium deficiency 38:18 Why Juvent alone won't fix osteoporosis, and the physician-guided programs seeing 3 to 6 percent bone density gains a year  Schedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: Juvent - https://www.juvent.com/  Juvent Bone Health and Osteoporosis Foundation - https://www.juvent.com/blogs/news/juvent-launches-next-generation-bone-health-supplement-hydroxybmd3-at-the-national-bone-health-amp-osteoporosis-foundation-bhof-symposium-in-washington-dc-2 Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Amy Kurtz | You're Cured, So Why Don't You Feel Better? Medical Trauma Brain

    What happens when your body finally heals, but the rest of you never got the memo? In this episode of The Dr. K Show, Dr. K sits down with Amy Kurtz, health coach, patient advocate, and author of But You Look Fine, to talk about a stage of recovery almost nobody prepares you for. After decades of misdiagnosis and a late stage neurological Lyme diagnosis, Amy got physically better, and then fell apart in a completely different way. She named it Medical Trauma Brain: the nervous system staying locked in survival mode long after the illness itself is gone. They talk about why medicine is built to treat parts of the body instead of the whole person, why "you look fine" can feel like the loneliest sentence in the English language, and what actually helps when someone you love is struggling with something you can't see. If you've ever felt like your body healed before your mind did, or you're supporting someone who has, this conversation gives you language for something you may have felt for years without a name for it. Key Takeaways: 0:00 Introduction 1:46 Why it took 36 doctors to finally name Medical Trauma Brain 6:36 Medical Trauma Brain, when your body heals but your nervous system doesn't get the memo 9:13 Why treating recovery as "sick vs. well" keeps patients stuck 15:40 Feeling fine and still far away, the mask patients wear in public 20:48 The loneliness epidemic hiding inside invisible illness 30:15 What people going through illness actually need, to be seen, heard, and believed 33:49 The best thing to say to someone who's struggling, and a Tig Notaro story that proves it Schedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: But You Look Fine (Amy Kurtz's book) - https://amykurtz.com/but-you-look-fine/ Amy Kurtz - https://amykurtz.com/ Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.

    Martha Carlin │ How Gut Bacteria and Glyphosate Fuel Parkinson's Disease

    What if Parkinson's disease doesn't start in the brain at all, but in the gut? In this episode of The Dr. K Show, Dr. Michael Karlfeldt sits down with Martha Carlin, citizen scientist, founder of BiotiQuest and The Bio Collective, and author of Connected, to unpack the 22-year journey she and her husband John lived after his Parkinson's diagnosis at age 44. Martha explains how removing processed food and GMO soy changed John's visible tremors within months, and how that discovery pulled her out of a corporate career and into two decades of independent microbiome research. The conversation moves through the science she uncovered along the way: the glycocalyx, the gel-like layer coating every cell in the body; how endotoxin from gut bacteria drives chronic inflammation across dozens of diseases; why H. pylori can quietly eat the dopamine that Parkinson's medication is supposed to deliver; and a striking account of fecal transplants shrinking tumors in cancer patients within two weeks. Martha also breaks down why endurance athletes face a hidden Parkinson's risk tied to the very same gut mechanisms. If you or someone you love is navigating a Parkinson's diagnosis, or you simply want a clearer picture of how the gut shapes chronic disease, this episode reframes the conversation. Key Takeaways: 0:00 Introduction 1:51 Husband John's Parkinson's diagnosis at 44 7:03 Removing processed food eliminated his visible tremors 15:46 The glycocalyx: the fuzzy layer controlling every cell 28:06 Endotoxin as the hidden driver of chronic disease 35:25 Fecal transplants shrinking tumors within two weeks 43:42 Why endurance athletes face a hidden Parkinson's risk  Schedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902 Resources: Connected: Love, Loss, and the Unseen Forces Behind Chronic Disease - https://a.co/d/0af28yWa BiotiQuest - https://biotiquest.com Martha's Quest - https://marthasquest.com  Medical Disclaimer: This content is for educational purposes only and is not intended to diagnose, treat, cure, or replace professional medical advice.
