Vitamin K2 (MK-7) and Coronary Artery Calcification: Insights from a 2-Year Trial: Nutritionist Leyla Muedin discusses a two-year randomized clinical trial in JAMA Cardiology from Maastricht University Medical Center reporting that daily vitamin K2 (menaquinone-7, MK-7) at 360 mcg slowed progression of coronary artery calcification (CAC) in 180 patients with confirmed atherosclerotic cardiovascular disease and baseline CAC 50–400 Agatston units. Compared with placebo, consistent MK-7 use was associated with 29% lower CAC progression and 42% less arterial calcium mass progression, though CAC still increased in both groups; stenosis increases were numerically lower with MK-7 but not statistically significant. Leyla notes many participants were on statins and were smokers, highlighting that statins can raise CAC by stabilizing soft plaque via calcification. The trial suggests MK-7 may slow calcification in newer plaques, may improve arterial elasticity via matrix GLA protein activation, is inexpensive and safe, but clinical event reduction remains unproven; Leyla suggests considering MK-7 (possibly 360 mcg) with vitamin D, magnesium, and dietary measures.

Dr. Hoffman continues his conversation with Nathan Jones, founder and CEO of Xlear, Inc.

Nathan Jones, founder and CEO of Xlear, Inc., reveals xylitol's role in supporting oral and nasal “gateway” microbiomes by selectively starving acid-producing Strep mutans rather than indiscriminately killing bacteria, and warns that harsh mouthwashes can disrupt beneficial oral bacteria linked to nitric oxide production and possibly blood pressure. Jones outlines Spry and Xlear products (gum, mints, toothpaste, mouthwash, dry-mouth “Rain,” and upcoming gummy candies, a new dental probiotic with added nutrients, and a direct-to-consumer oral bacteria test kit with pre/post tracking). He discusses diet, emphasizing sugar as a key driver of cavities and criticizing limited focus on sugar in a Surgeon General oral health report. In part two, Jones describes ongoing and planned legal actions against the FTC over shifting evidentiary standards and reputational damage, then reviews Xlear's allergy and respiratory approach via nasal hygiene, product tiers (regular, Max with quercetin, Rescue botanicals, and a decongestant), and a forthcoming ectoine-based spray to support mucus barrier integrity.

Dr. Hoffman continues his conversation with Dr. Nathan Bryan, international Leader in Molecular Medicine, the first to describe nitrite and nitrate as indispensable nutrients required for optimal cardiovascular health. 

Nitric Oxide Explained: Vascular Health, Exercise Performance, and N1o1 with Dr. Nathan Bryan, international Leader in Molecular Medicine, the first to describe nitrite and nitrate as indispensable nutrients required for optimal cardiovascular health. He details NO as a ubiquitous messenger affecting blood flow, erectile function, cognition, exercise performance, endothelial dysfunction, and aging-related declines in NO production. Bryan explains why PDE5 inhibitors like Viagra prolong cyclic GMP signaling but don't fix NO deficiency, and why beet products often fail due to variable nitrate content and inadequate dosing. He outlines his NO lozenge approach that generates NO gas from sodium nitrite and magnesium ascorbate, plus a fermented beet powder drink (NOBeets), and emphasizes the role of oral bacteria (and harms of antiseptic mouthwash/fluoride) in nitrate conversion. They review published endpoints, including flow-mediated dilation, blood pressure effects, inflammation markers, triglycerides, stem cells, plaque regression, applications to Alzheimer's, glaucoma/microvascular disease, safety/dosing considerations, risks of arginine supplementation, and a dual-chamber topical NO serum developed from wound-healing experience.

Sleep, Glymphatic Detox, and the Hidden Heart Risks of Sleep Apnea: Nutritionist Leyla Muedin explains how sleep supports brain “housekeeping” via the glymphatic system, a glial-lymphatic waste-clearance network most active during sleep that moves cerebrospinal fluid through brain spaces to remove metabolites and toxic proteins such as amyloid beta, with sleep deprivation linked to amyloid accumulation. She notes other clearance pathways, including meningeal lymphatic vessels, whose impaired function is associated with neurodegenerative disease and brain injury. Reviews of human studies suggest sleep influences glymphatic outcomes, though results are inconsistent and methods vary. She emphasizes that poor sleep is associated with dementia risk, depressive symptoms, cardiovascular events, mortality, and impaired glucose metabolism, and highlights lifestyle strategies that may improve sleep. She warns that untreated obstructive sleep apnea accelerates cardiovascular aging via intermittent hypoxia and inflammation, raising blood pressure and cardiovascular event risk, while treatment (e.g., CPAP) may halt or reverse damage.

Dr. Hoffman continues his conversation with pediatrician and author Dr. Elizabeth Mumper.

Pandemic Policies, Vaccines, and Harms to Children: pediatrician and author Dr. Elizabeth Mumper discusses her book “Kids and COVID: Costly Mistakes That Must Never Happen Again.” Mumper argues parents should question authorities, citing early pandemic decisions such as lockdowns, masking, and a “one size fits all” vaccine strategy despite children's low risk from COVID. She supports the Great Barrington Declaration's focus on protecting high-risk groups and criticizes suppression of repurposed treatments like hydroxychloroquine and ivermectin. The discussion raises concerns about mRNA vaccine safety, biodistribution of lipid nanoparticles, underreporting to VAERS, loss of long-term control groups, myocarditis risk in young males, and claims of severe neurologic effects and “turbo cancers.” Mumper describes developmental, educational, and mental-health harms from masking and school closures, challenges vaccine mandates as violating informed consent, explains the cell danger response concept, and criticizes Paxlovid while favoring integrative approaches.

Perimenopause, Insulin Resistance, and Persistent Muscle & Joint Pain: A Functional Medicine Framework: Nutritionist Leyla Muedin discusses perimenopausal musculoskeletal symptoms—new or persistent joint pain, muscle aches, and tendon problems—and highlights a Clinician's Journal article by physical therapist Tara Moore proposing insulin resistance screening in perimenopausal musculoskeletal care. She explains that declining estradiol during the menopausal transition can worsen insulin signaling, increase visceral fat, and reduce insulin sensitivity, affecting skeletal muscle recovery and potentially contributing to tendinopathies and poor or short-lived responses to localized treatments like PT. The framework emphasizes assessing systemic metabolic contributors (e.g., sedentary behavior, high-carbohydrate nutrition patterns, PCOS, central weight gain, stress, sleep disruption) and addressing mediators such as inflammation and impaired glucose utilization. She suggests integrating metabolic risk assessment, sleep and stress strategies, resistance training, and interdisciplinary referrals, arguing that nutrition and supplementation—especially a low-carb approach—may improve recovery and pain outcomes.

Dr. Hoffman continues his conversation with Dr. Garth Nicolson, Founder, President, Chief Scientific Officer, and Emeritus Research Professor of Molecular Pathology at the Institute for Molecular Medicine in Huntington Beach, California, and Research Advisor for Nutritional Therapeutics.

Dr. Garth Nicolson, Founder, President, Chief Scientific Officer, and Emeritus Research Professor of Molecular Pathology at the Institute for Molecular Medicine in Huntington Beach, California, and Research Advisor for Nutritional Therapeutics, explains how membrane damage from free radicals and loss of mitochondrial transmembrane potential contribute to declining energy with age, noting studies in older adults showing improved energy output, fatigue, cognition, mood, and activity after NTFactor lipids, a protected phospholipid supplement balanced toward mitochondrial lipid composition. He describes evidence of lipid delivery using fluorescent-tagged lipids in sperm, with improved motility, and discusses applications including wound healing in veterans, removal of hydrophobic toxins via a concentration-driven “conveyor belt” process, and improved transport of nutrients like CoQ10. He details articles on normal aging, menopause-related changes supported by membranes, dementia risk linked to hearing loss, and rat studies showing delayed hearing loss with NTFactor, and mentions research on EMF sensitivity and planned schizophrenia trials.

Nutritionist Leyla Muedin discusses research showing simple strength tests—grip strength and a five-rep sit-to-stand chair test—predict longevity in older women. In a University at Buffalo study of over 5,000 women ages 63–99 followed for eight years, stronger grip and faster chair-stand times were linked to lower mortality; every additional 7 kg of grip strength corresponded to a 12% reduction in death risk, and faster chair-stands were also associated with improved survival, even after adjusting for activity, cardiovascular fitness, and inflammation. She emphasizes prioritizing muscle-strengthening alongside aerobic exercise and suggests accessible resistance options (weights, bodyweight moves, or household items) with professional guidance as needed. She then cites UK Biobank data linking long-term statin use to declines in grip strength and appendicular lean mass, urging discussion with physicians and added vigilance, especially for those also using GLP-1 drugs that may reduce protein intake and muscle mass.

In this episode of Girl Talk with Tay, I sit down with Neka Pasquale, founder of Urban Remedy, practitioner of Traditional Chinese Medicine, and longtime advocate for food as medicine, to discuss holistic health, organic living, entrepreneurship, and the everyday habits that support long term wellness.Neka shares how her journey began through studying Traditional Chinese Medicine and how that foundation shaped both her personal health philosophy and the creation of Urban Remedy. We talk about viewing the body as an interconnected system, why every food carries unique healing properties, and how living in alignment with natural rhythms can have a profound impact on overall well being.We also dive into the growing conversation around ultra processed foods, glyphosate, GMOs, inflammation, and metabolic health. Neka explains why choosing organic foods matters, what consumers should know about food quality, and how modern lifestyles have moved many people away from the foundational habits that support health.We discuss practical wellness habits including hydration, movement, sleep, stress management, seasonal eating, and creating sustainable routines that work in real life. Neka shares her perspective on avoiding extremes and instead focusing on simple daily practices that help the body function at its best.On the business side, Neka opens up about building Urban Remedy from a private acupuncture practice into a nationally recognized wellness brand carried in Whole Foods and healthcare systems across the country. We talk about scaling a mission driven company, raising capital, maintaining brand integrity, and why she believes entrepreneurs should stay independent for as long as possible.xo, Tay⸻Follow Neka Pasquale!

Dr. Hoffman continues his conversation with holistic practitioner Jane Jansen.

A Brand New Tool for Gut, Inflammation, and Brain Support: Holistic practitioner Jane Jansen details Essential Formulas' Dr. Ohhira's Postbiotic Fermented Food Concentrate, a non-GMO, gluten-free, dairy-free, capsule-free fermented paste in travel-friendly, non-refrigerated sachets. She explains the difference between probiotics and postbiotics, emphasizing that this concentrate delivers postbiotic metabolites (including short-chain fatty acids like butyrate, plus enzymes, amino acids, vitamins, peptides, and growth/repair factors) created via a five-year fermentation of 14 fruits, vegetables, mushrooms, and seaweeds; the paste contains no live probiotics because they are heat-killed. The discussion highlights use cases for people who don't tolerate fiber or probiotics (IBS, SIBO, Crohn's, ulcerative colitis), potential benefits for leaky gut, systemic inflammation, gut-brain/mitochondrial health, insulin resistance, children, and pets, and suggests it can complement Dr. Ohhira's capsules and may be taken less than daily.

Dr. Hoffman continues his conversation with integrative veterinarian Dr. Judy Morgan, DVM, CVA, CVCP, CVFT. 

Naturally Healthy Pets: Whole-Food Diets, Microbiome Repair, and Integrative Therapies with integrative veterinarian Dr. Judy Morgan, DVM, CVA, CVCP, CVFT. She argues that pet ownership benefits human wellbeing and that pets concentrate household toxins, warning against routine pesticide-based flea/tick and other veterinary drugs due to environmental contamination and adverse events. She recommends species-appropriate whole-food diets (cats as obligate carnivores; dogs mostly meat) and criticizes ultra-processed pet foods, synthetic nutrient premixes, grains/legumes in kibble, and high-carb diets that fuel yeast and inflammation; she discusses safe calcium, zinc, and vitamin D sources. In part two, she describes veterinary acupuncture, chiropractic, and laser/red-light therapies with case examples, links skin/ear “allergies” to gut dysbiosis, uses microbiome testing, FMT capsules, and detox support, highlights omega-3s, PEA for pain, and CBD for seizures/anxiety, and outlines multi-layered natural flea/tick prevention.

Registered dietitian nutritionist Leyla Muedin discusses the growing interest in biological age versus chronological age and explains that biological aging is modifiable through consistent lifestyle choices. She outlines common measurement tools and biomarkers, including epigenetic clocks (DNA methylation), telomere length, VO2 max, inflammatory markers, grip strength, and muscle mass, noting that genetics account for only about 25–40% of biological aging variation. Key interventions include regular aerobic and resistance exercise, protein-adequate nutrition to preserve muscle and prevent sarcopenia (with whey protein and leucine-rich foods noted), improved sleep, stress management, reducing processed foods and visceral fat, and lowering chronic inflammation (CRP, IL-6). She also reviews hormetic stressors such as sauna use and mentions red/near-infrared light and sun exposure without sunglasses. Leyla shares client examples showing biological age can worsen or improve, and encourages repeat testing after lifestyle changes.

REPLAY! Most people think "grass-fed" tells the full story. According to Cloe Parker, it often does not, and that changes everything about how you shop for meat.On this episode of Wellness Junkies, host Amy Sherman sits down with Cloe, who runs Parker Pastures, for one of the most practical wellness conversations the show has had. Cloe returned home after her mother was diagnosed with cancer and officially took over Parker Pastures right before she turned 20. Her mission since then has been simple. Help families understand what they are eating and why it matters.The wellness tips she shares here are not about supplements or skincare routines. They are about the food most of us buy every week without thinking twice. Cloe breaks down why the "grass-fed" label lost its regulatory meaning in 2016, what grain finishing does to the omega-3 to omega-6 ratio in beef, and what fat color and meat color actually tell you about quality. She also gets into chicken processing, including the bleach bath most commercial chicken goes through before it hits the shelf.These are not wellness hacks you will find in a listicle. They are honest wellness conversations about the food system itself, the kind of relatable wellness conversations that make you rethink your next grocery run. Cloe also shares her wellness routines, from clean food and protein to faith, time in nature, and staying grounded in something real.Whether you are searching for the best wellness products or want better wellness tips for everyday life, this episode gives you a clear framework for both.Episode Breakdown:00:00 How Cloe Parker Took Over Her Family's Meat Company03:32 The Truth About Grass-Fed Labels and What They Actually Mean05:42 How to Tell If Your Meat Is Really Grass-Fed, Grass-Finished13:04 The Truth About Grocery Store Chicken and Bleach Baths13:43 How to Order From Parker Pastures and Buy Meat in Bulk18:19 The State of the Food Industry and Why Small Farms Need Your Support23:01 Wellness Tips From a Rancher: Nature, Clean Food, and Daily GroundingConnect with Cloe Parker:Follow Cloe on InstagramFollow Parker Pastures on FacebookVisit the Parker Pastures websiteUse code "WELLNESS" at checkout for 10% off at ParkerPastures.com, other links on prior episode page on website ⁠⁠⁠⁠⁠For More on this Episode: Read the full show notes ⁠⁠⁠⁠⁠here⁠⁠⁠⁠⁠

Dr. Hoffman continues his conversation with Dr. Corey Schuler, PhD(c), FNP, DC, CNS, and director of medical affairs at Allergy Research Group.

Dr. Corey Schuler, PhD(c), FNP, DC, CNS, and director of medical affairs at Allergy Research Group, details his paper “Energy Allocation Resilience and Endocrine Integration” in the International Journal of Molecular Sciences. He introduces the Energy Allocation System (EAS), which emphasizes how the body allocates energy—not just produces it—and links many symptoms to impaired bioenergetics and resilience. They discuss mitochondria as energy generators and cellular signaling hubs, the integrated stress response and endocrine coordination (HPA axis, thyroid, gonads), and mitohormesis/eustress (exercise, fasting, heat/cold, circadian “zeitgebers”). Schuler explains nuanced testing for fatigue (diurnal cortisol, CGM patterns, thyroid markers including T3/reverse T3) and a case of a perimenopausal woman where oral contraceptives and cortisol dysregulation affected glucose patterns. They cover mitochondrial support (removing obstacles like pollutants/antibiotics, triglycerides, carnitine, dietary fats, micronutrients) and pacing/sequencing lifestyle interventions.

Eccentric Exercise: Better Results with Less Effort. Leyla Muedin, a registered dietitian nutritionist, discusses eccentric exercise and research suggesting it may deliver better results than strenuous workouts that cause muscle damage and delayed onset muscle soreness (DOMS). She explains contraction types—isometric, concentric, and eccentric—highlighting that eccentric contractions involve muscle lengthening during the lowering phase (e.g., lowering a dumbbell, walking downstairs) and can provide greater mechanical loading with lower perceived effort, less fatigue, and broad accessibility across ages and health conditions, though requiring more focus and control. She cites studies including stair-descending in elderly obese women improving cardiovascular function, insulin sensitivity, cholesterol, and strength, and a five-minute home routine (chair squats, wall pushups, chair reclines, heel drops) improving strength, flexibility, mental health, and encouraging continued exercise. She notes athletic benefits and the need for further research.
