    Are We Killing Our Pets with Dr. Judy Morgan | Improvement Warrior Podcast Episode 91

    Are We Killing Our Pets with Dr. Judy Morgan | Improvement Warrior Podcast Episode 91 Are We Killing Our Pets? That’s the question Jason Yun poses in this powerful conversation with holistic veterinarian Dr. Judy Morgan on the Improvement Warrior Podcast. Conventional care—ultra-processed kibble, annual vaccines, chemical flea/tick preventatives, and corporate-driven protocols—has coincided with exploding rates of cancer, kidney disease, allergies, and shortened lifespans in dogs and cats. Dr. Morgan, with 40+ years of integrative experience, pulls no punches on what’s going wrong and how pet parents can take back control with species-appropriate food, smarter vaccination strategies, and natural therapies. Welcome back to the Improvement Warrior Podcast. If you’re new, this is the show where we go beyond calories and cardio and talk about the things that actually move the needle: light, mitochondria, circadian biology, and now… the animals who share our homes. I recently lost my own dog. That experience, combined with everything I’ve learned about how environment and inputs shape biology, made me ask a hard question: Are we accidentally killing our pets with the very care we think is protecting them? Today I’m sitting down with Dr. Judy Morgan, DVM, CVA, CVCP, CVFT—integrative veterinarian, bestselling author, and one of the loudest, most consistent voices for naturally healthy pets. She retired from clinical practice after 36 years and now educates millions of pet parents on real food, reduced chemical load, smarter vaccination, and traditional Chinese veterinary medicine.This conversation is going to challenge a lot of what you’ve been told at the vet’s office. Grab your notebook. Let’s go. Detailed Timestamp with Show Highlights 0:00 – 7:45 — Jason’s cold open, personal story of losing his dog, why this episode matters, and the core thesis: light + environment + inputs apply to pets too.7:45 – 14:20 — Dr. Judy’s background: 40+ years in practice, shift from conventional to integrative, why she left clinical work to educate at scale.14:20 – 22:10 — The rise in chronic disease: cancer, kidney failure, allergies, IBD.

    Permanent Daylight Saving Time MUST BE STOPPED! Improvement Warrior Podcast Episode #90

    Permanent Daylight Saving Time MUST BE STOPPED! Improvement Warrior Podcast Episode #90 Hey Improvement Warriors, Jason Yun here — welcome back to the Improvement Warrior Podcast, Episode 90. I’m a former gym owner and food-and-exercise guy who finally saw the light (literally). Since 2018 I’ve been deep in the teachings of Dr. Jack Kruse and circadian biology. My core message never changes: your light environment is more important than food or exercise. In this episode we’re tackling something urgent and timely — the push for Permanent Daylight Saving Time. Politicians are once again trying to lock us into dark winter mornings forever. I’ll break down exactly why this is a biological disaster, how it wrecks your mitochondria, sleep, hormones, and energy, and what we must do to stop it. Grab your blue blockers, get some real sunlight if you can, and let’s go. Time Stamp and Highlights of the show 0:00 – 4:30 – Cold open & welcome. Jason introduces Episode 90 and the core thesis: Permanent Daylight Saving Time must be stopped. 4:30 – 12:00 – Quick recap of past DST episodes (especially Episode 82 “Daylight Saving Time Sucks”) and why the current political push (Sunshine Protection Act) is different and more dangerous. 12:00 – 22:00 – History of DST, energy-saving myths debunked, and the real biological cost of shifting clocks away from solar time. 22:00 – 34:00 – Deep dive into circadian biology: morning sunlight as the master zeitgeber, SCN, melatonin, cortisol, and why late winter sunrises under permanent DST create chronic misalignment (effectively permanent social jet lag). 34:00 – 42:00 – Health consequences: increased accidents, heart attacks, depression, cancer risk gradients across time zones, school performance, and mitochondrial dysfunction. 42:00 – 52:00 – Outdoor sunlight segment (shirtless, grounded). Live demonstration of proper morning light exposure and why dark mornings destroy the signal. 52:00 – 60:00 – Practical action steps: what individuals can do right now, how to contact legislators, better alternative (permanent Standard Time), and tie-in to full circadian lifestyle.

    T3 + Vitamin A = LDL + Pregnenolone = All Sex Steroid Hormones

    T3 + Vitamin A = LDL + Pregnenolone = All Sex Steroid Hormones The Critical Biochemical Pathway Most People Never Learn About In this episode of the Improvement Warrior Podcast (Substack, Apple), Jason Yun breaks down a critical biochemical pathway: how T3 (the active form of thyroid hormone) works with Vitamin A to help utilize LDL cholesterol, which then supports the production of pregnenolone — the precursor to all sex steroid hormones (testosterone, estrogen, progesterone, etc.). Jason explains the interconnected roles of these molecules in energy production, hormone balance, fertility, mood, and overall vitality. He connects this pathway to his core teachings on circadian biology, mitochondrial health, and the importance of proper light exposure. The discussion highlights why disruptions in this chain are common in modern life and offers practical insights into supporting it naturally through lifestyle, nutrition, and environment. Whether you’re dealing with low energy, hormonal imbalances, or simply want to understand how your body produces and regulates sex steroids at the deepest level, this episode delivers clear, actionable knowledge rooted in real biology rather than conventional approaches. Timestamp Log 0:00 – Intro & welcome to Episode 89 1:10 – Overview of the key pathway: T3 + Vitamin A 3:45 – Role of LDL Cholesterol in the process 6:20 – Pregnenolone as the mother hormone 9:00 – How this leads to all sex steroid hormones 11:30 – Practical implications for energy, hormones & vitality 13:45 – Ties to circadian biology, light exposure, and mitochondria 15:30 – Key takeaways and action steps 16:40 – Closing thoughts & outro Resources Mentioned Improvement Warrior Newsletter Patreon Substack One Tap Zap Magnesium Breakthrough

    No Sunscreen Ever? Dermatology vs. Circadian Biology – Why One Expert Says Ditch SPF for Good: Sunscreen Part 2 Unknown Death Causers Part 8 | Improvement Warrior Podcast Episode 88

    No Sunscreen Ever? Dermatology vs. Circadian Biology – Why One Expert Says Ditch SPF for Good: Sunscreen Part 2 Unknown Death Causers Part 8 | Improvement Warrior Podcast Episode 88 Should you never wear sunscreen again?In this episode, we explore Jason Yun’s powerful Substack argument — 'No Sunscreen Ever? Dermatology vs. Circadian Biology.' While mainstream dermatology insists on daily SPF to prevent cancer and aging, circadian health experts like Jason make a compelling case that sunscreen blocks vital sunlight signals our bodies need for vitamin D, melanin production, hormone balance, and mitochondrial health. Show highlights The Core Clash: Mainstream dermatology pushes daily sunscreen to prevent skin cancer and photoaging, while circadian biology views sunlight as essential medicine that sunscreen actively blocks.Vitamin D Sabotage: Even SPF 8 blocks 92–95% of vitamin D production; higher SPFs (30/50/75) are even more restrictive — turning one of the sun’s biggest health benefits into a non-event.Chemicals in Your Bloodstream: Sunscreen ingredients are absorbed through the skin (the body’s largest organ). Circadian Disruption on the Skin: Sunscreen blocks critical light signals to opsins and chromophores in the skin, interfering with POMC processing, hormone signaling (dopamine, alpha-MSH), and the skin’s own circadian clocksThe “Solar Callus” Concept: Gradual, properly sequenced sun exposure (sunrise first, then UVA/UVB) allows the body to build natural melanin armorMelanin Is Your Superpower: Far more than cosmetic tanning — melanin acts as a potent antioxidant, mitochondrial protector, and biological sunscreen that modern indoor lifestyles + seed-oil-heavy diets have made us lose.Host’s 8+-Year Experiment: Jason Yun stopped using sunscreen after his 2011 honeymoon, built a base tan through consistent exposurePhotoaging Reconsidered: Wrinkles and elastosis aren’t solely caused by UV — proper sun exposure (in the right sequence) can actually support collagen, elastin, and hyaluronic acid production. Why We’re More Sun-Sensitive Today: Modern factors (chronic indoor living, blue light/EMF overload, high omega-6 diets, magnesium deficiency) make skin burn easier. The solution isn’t more sunscreen — it’s fixing the underlying environment.Sunscreen & Melanoma Paradox: The article highlights research suggesting sunscreen users can have higher melanoma risk, possibly due to longer intentional sun exposure combined with blocked benefits and toxic ingredients.Dermatology Critique: Dermatologists are trained in a system called “Rockefeller medicine” — focused on treating symptoms and creating lifelong patients rather than optimizing the skin as a light-sensing, hormone-producing organ.Broader Systemic Wins from Sunlight: Beyond skin, proper exposure boosts nitric oxide, supports sulfated vitamin D, enhances immunity (cathelicidin), improves mitochondrial function, lengthens telomeres, and strengthens circadian alignment for better sleep, mood, and metabolism.Resources Mentioned Newsletter: http://www.improvementwarriorfitness.com/nlPatreon: http://www.improvementwarriorfitness.com/patreonPodcast Support Kofi; http://www.improvementwarriorfitness.com/kofiUnknown Death Causer Podcast on Sunscreen (UDC #2 / Episode 36): http://www.improvementwarriorfitness.com/sunscreenVitamin D episode (Episode 5): http://www.improvementwarriorfitness.com/iwp5Breast cancer & Vitamin D (adolescent exposure): https://aacrjournals.org/cebp/article/16/3/422/260255/Vitamin-D-and-Reduced-Risk-of-Breast-Cancer-A Sunscreen absorption study: "Effect of Sunscreen Application Under Maximal Use Conditions on Plasma Concentration of Sunscreen Active Ingredients" (JAMA randomized clinical trial).
