Vitamin B12 Deficiency--The “Aging” Symptoms You Shouldn't Ignore: Leyla Muedin, a registered dietitian nutritionist in New York City, discusses vitamin B12 deficiency as a common problem that can mimic normal aging, noting adults need only about two micrograms daily to support red blood cells, nerves, and DNA. She reviews the history of liver treatment for pernicious anemia and explains that deficiency remains common in older adults, vegans/vegetarians, and people with impaired absorption due to low stomach acid, autoimmune gastritis, weight loss surgery, or medications such as metformin and proton pump inhibitors. Symptoms can develop slowly and include fatigue, weakness, shortness of breath, numbness/tingling, poor balance, memory issues, and brain fog; she advises medical evaluation and B12 testing rather than assuming aging or relying on wellness-clinic injections when levels are normal. She emphasizes B12 is primarily in animal foods, so vegans need supplements, and notes broader nutrient shortfalls she sees in vegan clients.

Dr. Hoffman continues his conversation with Dr. David Chernoff, Chief Medical Officer of Setpoint Medical.

Dr. David Chernoff, Chief Medical Officer of Setpoint Medical, discusses electrically driven vagus nerve stimulation (VNS) as a “neuroimmune modulation” approach to autoimmune and inflammatory disease. Chernoff explains the vagus nerve's sensory role in monitoring organs and signaling the brainstem and spleen to regulate immune responses, and how precise stimulation can reduce pro-inflammatory cytokines without immunosuppression. Setpoint's miniaturized, wireless, MRI-compatible implant is placed in an outpatient 45-minute neck procedure and delivers one minute of daily stimulation titrated to an upper comfort level; long-term safety is supported by prior surgical experience and a 242-patient blinded RA study with two-year data, leading to FDA approval for rheumatoid arthritis. The discussion covers add-on use with medications, potential steroid tapering, reimbursement, and research in Crohn's disease, relapsing MS (vision and remyelination), and other conditions, including psoriatic arthritis, lupus, and neurodegenerative diseases.

Registered dietitian Leyla Muedin discusses a Frontiers in Microbiology paper suggesting certain probiotics may help sequester heavy metals. The study, sponsored by the Italian company Probiotical and conducted with University of Ghent and University of Piedmont Orientale, researchers used in vitro testing and the SHIME gut simulator to assess Lactiplantibacillus plantarum, Lactobacillus crispatus, and Lactobacillus acidophilus against cadmium, lead, chromium, and mercury. L. plantarum and L. crispatus reduced metal bioavailability primarily in the simulated colonic phase, while L. acidophilus showed minimal detoxification; mercury was least reduced (~10%). An ex vivo mouse-intestine system found probiotic pre-incubation of metals preserved epithelial integrity and reduced inflammatory responses. Leyla notes limitations: corporate funding, only three strains tested, and no in vivo or human trials, though the findings support further animal and clinical research.

Immune Regulation, Omega-3 Nuance, and Himalayan Tartary Buckwheat with Dr. Austin Perlmutter, chief science officer of Big Bold Health. He details immune regulation as a nuanced, multidimensional system shaped by diet and lifestyle rather than simple “boosting.” Perlmutter explains Big Bold Health's focus on immunometabolism, educating about immune complexity, and conducting studies on nutraceuticals, including use of CGMs and clinical trials. He discusses why eating fish often outperforms refined fish-oil supplements, noting conventional processing (heat, bleaching, deodorizing, esterification) and loss of other lipids and nutrients. Perlmutter highlights specialized pro-resolving mediators (resolvins, protectins, maresins) and vitamins A and D as potentially better preserved in minimally processed oils, and reviews typical omega-3 intake and target ranges. The conversation also covers immunosenescence/inflammaging and Big Bold Health research on sprouted Himalayan Tartary Buckwheat, its high polyphenols (rutin, quercetin), microbiome effects, and studies including epigenetic aging clocks and brain outcomes.

Dr. Hoffman continues his conversation with Dr. Austin Perlmutter, chief science officer of Big Bold Health. 

Dr. Hoffman continues his conversation with physician and molecular biologist Dr. Adrian Woolfson, co-founder of Genyro, a biotechnology company specializing in synthetic genome design and construction, and author of “On the Future of Species: Authoring Life by Means of Artificial Biological Intelligence.”

AI and Generative Biology: Authoring Life, Redesigning Healthcare, and Building Guardrails: Physician and molecular biologist Dr. Adrian Woolfson, co-founder of Genyro, a biotechnology company specializing in synthetic genome design and construction, and author of “On the Future of Species: Authoring Life by Means of Artificial Biological Intelligence,” discusses the convergence of AI with synthetic/generative biology that could make biology programmable and enable genome design and construction beyond traditional gene editing. Woolfson argues that the technology is morally neutral but is arriving rapidly and requires public awareness, governance, and guardrails due to risks, including misuse by authoritarian regimes and biological warfare. He discusses evolution's trade-offs and why he favors limiting human applications to curing disease and extending healthy longevity, while opposing germline modification; he explains germline vs somatic editing and cites the flawed, unethical case of a Chinese scientist attempting inherited HIV resistance. They examine sickle cell disease cures costing $2–$3 million, scalability issues, and trade-offs like malaria protection, and highlight non-medical benefits such as engineered crops, biomaterials, desalination, and DNA-based information storage.

Bone Health Beyond Calcium: Vitamin D, K, Protein, Medications, and Metabolic Risks: Registered dietitian nutritionist Leyla Muedin discusses factors affecting bone health, osteopenia/osteoporosis, and limitations of bone mineral density as a measure of bone strength. She emphasizes optimizing vitamin D via 25-hydroxy D testing (aiming roughly 55–85 and avoiding over 100), ensuring vitamin K for proper calcium placement, and addressing malabsorption from GI conditions, food intolerances, or inflammation. She notes long-term proton pump inhibitor use can impair calcium and magnesium absorption and increase osteoporosis risk. Diet considerations include avoiding overly grain-heavy, acid-forming patterns and ensuring high biological value protein; she also mentions heavy metals affecting bones. Additional assessment includes magnesium and DHEA sulfate, plus resistance and balance training (ideally three times weekly). She highlights research linking hyperinsulinemia/type 2 diabetes/cardiovascular disease to fragility fractures despite normal or higher bone density, proposing carbohydrate restriction, fasting, and ketosis to improve bone remodeling via osteocalcin and mitochondrial function.

A longtime listener recently dug through his collection of Joe's old Ask Joe Q&A's, T Nation articles, and EliteFTS posts from over 20 years ago… and he challenged Joe to critique his own advice! In this episode, Joe revisits five classic topics - including box squats, vertical jump training, free weights vs. machines, strength vs. hypertrophy principles, and full-body training splits - to answer one simple question: "Would 2026 Joe D. give the same advice as 2006 Joe D.?" Some recommendations stood the test of time almost exactly as Joe originally taught them… while a few have evolved after two more decades of coaching thousands of athletes, lifters, and everyday clients. It's an honest, entertaining look at what experience reinforces, what research has refined, and why the best coaches are never afraid to re-evaluate their own beliefs. *For a full list of Show Notes with Timestamps visit www.IndustrialStrengthShow.com   IMPORTANT LINKS Lean Bastard VIP List DeFranco's Nutritional Supplements

Cardiovascular Protection Beyond Statins--Nattokinase, Vitamin K2 MK-7, and Clinical Cardio Six: Neil Levin of NOW Foods/Protocol for Life Balance details cardiovascular protection beyond cholesterol-lowering drugs, emphasizing nutrient sufficiency, therapeutic “nutraceutical” dosing, and physician partnership with testing. They discuss nattokinase from fermented natto (typical 2,000 fibrinolytic units/day), describing research on reduced fibrinogen, improved blood viscosity and microcirculation, blood-pressure normalization, and higher-dose data suggesting benefits for arterial thickness and lipids without excessive blood-thinning. They review vitamin K: K1 for normal coagulation (risk with Coumadin relates to day-to-day variability) and K2 for calcium metabolism, highlighting MK-7's longer half-life and potency versus MK-4 and recommending pairing K2 with vitamin D. Levin outlines PFLB Clinical Cardio Six (D3, L-carnitine, hawthorn leaf/flower, solubilized grape seed extract, CoQ10, MK-7), ingredient sourcing/testing, omega-3 benefits, red yeast rice context, and controversy around vitamin E meta-analyses.

Dr. Hoffman continues his conversation with Neil Levin, the Senior Nutrition Education Manager and a product formulator for NOW(r) Foods and Protocol for Life Balance. 

Dr. Hoffman continues his conversation with Jen Scheinman, MS, RDN, CDN, Director of Science Communications at Timeline. 

Urolithin A (Mitopure) and Mitochondrial Renewal--Muscle, Immune, and Skin Benefits: Jen Scheinman, MS, RDN, CDN, Director of Science Communications at Timeline details urolithin A and Timeline's branded supplement Mitopure. She describes urolithin A's discovery through pomegranate research and worm studies showing a 45% lifespan increase. She discusses human research including improved walking distance and clinical outcomes in muscle endurance and strength. Urolithin A is presented as supporting mitochondrial health by promoting mitophagy—recycling damaged mitochondria—distinct from other mitochondrial supports like CoQ10 and NAD precursors. They explain most people cannot produce enough urolithin A from foods because only 30–40% convert precursors via the microbiome and it would require about six cups of pomegranate juice daily. Dosing discussed is 500–1,000 mg/day via gummies, capsules, or powder, with effects developing over months. She reviews emerging research on immune aging, preclinical work on brain and neurodegenerative conditions, and topical urolithin A for skin.

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.

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 Nathan Jones, founder and CEO of Xlear, Inc.

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.

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.
