The Science of Longevity with Dr. Chris Renna | Rational Wellness Podcast 465

Longevity Medicine Deep Dive with Dr. Chris Renna: Lifestyle Foundations, Stem Cells, Regenokine & Rapamycin Dr. Ben Weitz welcomes longevity physician Dr. Chris Renna of Lifespan Medicine to discuss evidence-informed longevity and joint regeneration strategies. Renna argues that 90% of aging outcomes still come from diet, exercise (including resistance training), sleep, and psychological perspective, with supplements and hormones as important supports. He explains why stem cells are often overhyped, why many donor cells die quickly, and describes Muse cells as a type that can survive longer, noting Florida's approval of umbilical cord cells for osteoarthritis and Lifespan's plans to offer Muse cells. Renna outlines aging as incomplete daily repair beginning around age 30 and reviews Regenokine (autologous serum rich in anti-inflammatory factors/exosomes) as a top-performing joint injection without cartilage regrowth. He covers mitochondrial support, NAD precursors, urolithin A, peptides, and discusses low-dose intermittent rapamycin plus fisetin to reduce senescent cells, ending with a message of gratitude and presence.

Using Precision Medicine to Reverse Alzheimer's Disease with Dr. Heather Sandison | Rational Wellness Podcast 464

Dr. Ben Weitz interviews Dr. Heather Sandison about a precision, multimodal approach to Alzheimer's and cognitive decline that challenges the amyloid-only model. Sandison cites a 2026 Cochrane review finding anti-amyloid antibody therapies remove plaque but don't meaningfully improve cognition and carry risks like brain bleeding and swelling, arguing cognitive decline is driven by multiple modifiable factors. She reviews lifestyle-intervention research (Bredesen/Toups 2022, her 2023 study, Ornish 2024, and the Alzheimer's Association POINTER trial) showing cognitive improvements, discusses key drivers such as toxins (mycotoxins, metals, chemicals), infections, metabolic flexibility/ketosis, sleep, stress, and social connection, and outlines evaluation tools including MoCA, CNS Vital Signs, MRI volumetrics with arterial spin labeling, and blood biomarkers like p-tau217, Aβ 42/40, and NfL, plus interpreting nutrients via homocysteine.

Dr. Kate Davis on Parasites, "Drainage," and Functional Strategies for Chronic Gut Symptoms Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Kate Davis, a chiropractor turned functional medicine practitioner specializing in gut health. Davis recounts developing severe constipation and bloating at 24, receiving limited GI options, getting relief from visceral/myofascial work, then later worsening symptoms after stress with brain fog and joint swelling. A functional medicine friend used a hair follicle test (Cell Wellbeing) that suggested parasites; Davis followed an individualized protocol (including CellCore products, herbs, binders, Mimosa pudica seed, and TUDCA) and passed numerous parasites with symptom resolution. In practice she treats constipation, bloating, and loose stools by prioritizing "drainage" (bowel movements, liver/gallbladder/lymph function), assessing via hair scans, symptoms, stool/toxin tests, and bloodwork, and using diet, fermented foods, lifestyle, vagus/vestibular exercises, and breathwork; she discusses binders, mold, leaky gut, and insulin resistance targets, and shares contact info and an Instagram consult offer. 00:00 Show Intro 01:03 Meet Dr Kate Davis 01:33 Her Gut Health Journey 04:21 Parasites And Testing 06:30 Detox Protocol Basics 07:44 Practice Focus And Cases 09:06 Testing Leaky Gut 12:22 Parasite Treatment Strategy 13:58 Drainage And Gallbladder 16:18 Apollo Wearable Sponsor 17:51 4R Framework And Detox 21:04 Diet Probiotics Lifestyle 24:24 Gut Brain Vagus Nerve 28:46 Underrated And Overrated 32:04 Breathwork And Wrap Up 34:52 Podcast Outro

Dr. Barrie Tan on Tocotrienols: Annatto Vitamin E, Lipid Antioxidant Protection, and Clinical Uses Dr. Ben Weitz hosts Dr. Barrie Tan to discuss tocotrienols, lesser-known vitamin E family members (eight total: four tocopherols and four tocotrienols) that differ from common alpha-tocopherol-only supplements. Tan describes discovering tocotrienols in annatto in South America, noting annatto is uniquely tocopherol-free and rich in delta and gamma tocotrienols. He argues alpha-tocopherol is only clearly tied to bringing a fetus to full term and that excess alpha-tocopherol can antagonize tocotrienol absorption and clinical results. Tan emphasizes tocotrienols as superior lipid antioxidants that protect cell-membrane phospholipids and help stabilize omega-3 oils, and reviews studies and proposed benefits across fatty liver disease, metabolic syndrome/diabetes, dyslipidemia, inflammation markers, bone density in post-menopausal women and obesity, plaque-related endpoints, and selected cancers, plus discussion of radiation/antioxidant concerns and dosing ranges used in trials. 00:00 Show Intro and Mission 00:59 Meet Dr Barrie Tan 03:12 Annatto Discovery Story 08:03 Tocotrienols vs Tocopherols 11:20 Lipid Antioxidant Explained 16:16 Omega 3 Protection Strategy 20:34 Alpha Tocopherol Antagonism 24:26 Clinical Wins and Conditions 25:53 Obesity Study Results 30:33 Cancer Research and Ferroptosis 31:40 Delta Gamma Standouts 32:10 Iron Overload Ferroptosis Link 33:57 Apollo Wearable Sponsor 35:27 Antioxidants During Cancer Therapy 38:05 Radiation Countermeasure Evidence 43:31 Cancer Dosage Guidance 45:35 Heart Metabolic Benefits 49:35 Statins CoQ10 GG Explained 54:28 Black Seed Oil Combo 55:47 Books Vitamin K Wrap Up 58:10 Podcast Closing Credits Dr. Barrie Tan has a PhD in chemistry and he's spent his life dedicated to researching vitamin E, among other nutritional compounds.

The Fluoride Debate: Risks, Toxicity & Public Health with Dr. Paul Connett: RWP Episode 015

Dr. Ben Weitz interviews Dr. Paul Connett, a former chemistry and toxicology professor, on the possible dangers of fluoride toxicity. To begin with, there is no need in the human body for flouride and there is no disease associated with a lack of fluoride. Second, biochemists have known for a long time that flouride is very toxic and at high dosages it can kill you. Fluoride can interfere with enzymes, hydrogen bonds, and it combines with metal ions like calcium and magnesium, preventing them from the useful functions they have in the body. And these effects occur at low levels.

And then there are the health effects of flouride, including dental flourosis, which is a discoloration of the enamel of the teeth, and this occurs in over 50% of children in the US. And then we have potential damage to the brain, bones, thyroid, and the rest of the endocrine system, esp. in children. Over 50 studies document that levels of flouride that can easily occur in our children between water fluoridation, fluoride in toothpaste and mouthwash, and other sources of flouride, leads to lowering IQ by approximately 5 points! What an irrational way to deliver a potentially toxic drug to our population, given that there is no way to control the dosage. And may be giving a medication to people without their consent!

Dr. Connett has written many papers and several books, including his most recent, The Zero Waste Solution https://www.barnesandnoble.com/w/the-zero-waste-solution-paul-connett-phd/1115235807 and The Case Against Flouride https://www.barnesandnoble.com/w/the-case-against-fluoride-paul-connett/1021577574?ean=9781603582872 Here is Dr. Connett's website: http://www.americanhealthstudies.org/index.html While he is retired, Dr. Connett is available to speak at conferences.

Parkinson's Disease, Prions, and Root-Cause Brain Regeneration with Dr. Greg Eckel

Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Greg Eckel about Parkinson's disease, brain regeneration, and misfolded proteins (prions) such as alpha-synuclein. Eckel shares that his focus on neurodegeneration began after his wife died from Creutzfeldt-Jakob disease, motivating him to develop the Eckel Protocol and found Be Vital. He explains prions as misfolded proteins that propagate misfolding, discusses debates about whether alpha-synuclein may be protective, and argues Parkinson's reflects upstream systemic issues beyond dopamine loss. The conversation covers diagnostics (SYN-1 skin biopsy vs DaTscan), environmental toxins (TCE, paraquat, heavy metals), chelation approaches (provoked urine with DMSA), microbiome testing, and dietary guidance favoring Mediterranean/Zone patterns over keto. Eckel describes regenerative "brain camp" therapies including VSEL intranasal procedures, laser activation, exosomes, and adjunct modalities, and reviews supplements and IV therapies while emphasizing individualized testing and root-cause care.

Dr. Greg Eckel has degrees in both naturopathic medicine and Chinese medicine. After a deeply personal journey that reshaped his understanding of chronic illness, Dr. Greg Eckel has developed a comprehensive approach aimed not just at managing symptoms, but at restoring function and supporting the brain's capacity to heal. He has developed a brain regenerative program and a nasal spray that specifically targets neuroinflammation in the brain. He's also published a book, "Shake It Off: An Integrative Approach to Parkinson's Solutions." Dr. Eckel can be reached through his websites at brainregen.com, Bvital.com and on Instagram at @drgreckel.

Precision Medicine and Functional Approaches to Alzheimer's: Dr. Dale Bredesen on Personalized Treatment, Trial Results, and Key Drivers

Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews neurologist Dr. Dale Bredesen about a precision medicine approach to Alzheimer's, arguing cognitive decline reflects multiple interacting drivers rather than a single disease. Bredesen explains why a randomized controlled trial was needed to convince mainstream medicine, describes the ethical challenges of a declining control group, and reports statistically significant improvements in memory, executive function, processing speed, and neurocognitive index, including benefits for APOE4 carriers and preliminary improvement in APOE4/4 patients. He outlines key contributors— inflammation, toxicity, energetics, plus neurotransmitters, trophic support (including BHRT), and stress—along with common factors like metabolic dysfunction, mycotoxins, sleep apnea, infections, and heavy metals. The discussion covers early detection with blood biomarkers, individualized treatment variability by site training, diet (Ketoflex 12/3), stress-reduction tools, targeted supplements, and applications to other neurodegenerative syndromes.

Extend Your Healthspan through Cellular Optimization with Dr. Will Haas: Rational Wellness Podcast 459 Longevity and Healthspan: Cellular Optimization, Toxins, Testing, and Peptide Therapies with Dr. Will Haas Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Will Haas, founder of VYVE Wellness, about longevity as extending healthspan and maintaining function rather than simply living longer. They discuss preventable lifestyle risk factors behind chronic disease, major blind spots in conventional medicine (limited insurance-driven labs and reference-range thinking), and the value of deeper functional testing, including advanced cardiometabolic markers, toxins (heavy metals and mycotoxins), and gut health. Haas describes urine testing (Real Time Labs, Vibrant America), detox strategies, and therapeutic plasma exchange as a more aggressive option. He highlights body composition and heart rate variability as key assessments and reviews core lab categories (metabolic, inflammation, hormones, micronutrients, detoxification). They cover biological aging methylation tests, underused labs like fasting insulin and oxidized LDL, personalized diet interventions, peptide therapies (growth hormone secretagogues, tesamorelin, mitochondrial peptides), NAD strategies, limited use of senolytics, and the importance of hormone optimization and emerging omics such as metabolomics. 00:00 Show Intro 01:00 Meet Dr Will Haas 02:00 Longevity Defined 03:25 Lifestyle Risk Factors 05:16 Conventional Blind Spots 08:16 Advanced Cardio Markers 10:38 Toxins And Aging 13:17 Testing For Toxins 14:31 Therapeutic Plasma Exchange 17:55 Patient Workup Basics 19:43 HRV And Lab Strategy 24:10 Biological Age Testing 24:45 Sponsor Apollo Wearable 26:14 Underused Key Labs 28:10 Interventions Foundations 28:47 Clean Eating Defined 29:16 Gut Bloating and SIBO 29:59 Personalized Diet Strategy 30:51 Peptides and FDA Debate 32:41 Growth Hormone Controversy 34:23 Why Peptides Feel Safer 37:49 Choosing GH Peptides 40:09 GLP-1 Muscle Loss Fixes 42:30 Mitochondria and Energy 45:01 NAD Precursors and Sirtuins 47:37 Brain Health and Hormones 51:54 Longevity Myths and Methylene Blue 53:23 Future of Omics Testing 55:42 Final Takeaways and Contact

Dr. Joel Gould speaks to Dr. Ben Weitz about sleep apnea, deuterium, and vitamin D.

Podcast Details

I asked Dr. Gould how a dentist became an expert at sleep apnea? He found out he had sleep apnea and also discovered that patients did not want to go to a sleep lab to find out if they had it. He discovered that there were home methods of testing for sleep apnea, including using a pulse oximeter for two nights. He also discovered that the reason he had sleep apnea was because he had a vitamin D deficiency. This means that sleep apnea is both reversible and preventable. Dr. Gould also said that since he looks into patients mouths and shines a light down their throat, he's in a perfect position to discover the early signs of sleep apnea.

Dr. Gould described that if you have trouble breathing while you sleep, then you will probably be more comfortable sleeping sitting up in a chair. When he suspects a patient may have sleep apnea, he will send them home with a pulse oximeter to use for two nights that will record how much oxygen is in their blood and if it drops by 4 points or more when sleeping, it indicates sleep apnea.

Dr. Gould also discussed deuterium, what it is, and how much is in the environment. Deuterium is also known as a stable hydrogen isotope or heavy hydrogen, since while most hydrogen atoms have a proton and an electron, deuterium has a proton, an electron and a neutron. Thus, deuterium atoms are twice as heavy as other hydrogen atoms. Deuterium messes up your metabolism and can't function like regular hydrogen. More deuterium atoms will mess up the mitochondrial production of energy. If deuterium is incorporated into your genes, this creates genetic defects. Deuterium is the cause of aging, thus, deuterium is the rate limiting step of our life! Deuterium is also the cause of obesity and the reason why vegetarian or ketogenic diets work, because they reduce deuterium levels.

How to Change Habits with Amy Behimer: Rational Wellness Podcast 458

Dr. Ben Weitz introduces the Rational Wellness Podcast and interviews Dr. Amy Behimer a pharmacist turned board-certified health and wellness coach who helps people with autoimmune disease implement sustainable lifestyle changes through a structured, science-backed approach to "habit architecture." Behimer explains why behavior change is difficult, emphasizing that it is a learnable skill and that motivation is optional; she breaks motivation into belief, desire, and commitment. She outlines six research-backed reasons goals fail (including forgetting, goals being too big or not desired, lack of strategies that feel good, and no place to troubleshoot) and describes tactics such as "trust in the tiny," planning, tracking, reminders, support squads, environmental design, and focusing on one to three "now" habits using a tracker. She discusses mindset, compassion over guilt, household-level change, and offers a quiz, membership, and referral options for practitioners.

Dr. Amy Behimer is a pharmacist turned board certified health and wellness coach, and she specializes in helping people with autoimmune disease implement sustainable lifestyle changes. After her own diagnosis, she recognized that even the most precise. [00:02:00] Functional medicine recommendations fail without a repeatable system for behavior change. She now teaches a structured science-backed approach to habit architecture that helps patients move from knowing what to do to consistently doing it. Amy is the host of the Autoimmune Health Secrets Podcast. She's the founder of Club Habit Hub, where she works with high information patients who want better outcomes without burnout.
