    #233 Understanding NAD+: Insights with Dr. Charles Brenner

    Charles Brenner breaks down what the science actually says about NAD+, separating established findings from the claims commonly made in the longevity space. He explains why NAD levels in tissues may matter more than blood measurements, how metabolic stress, alcohol, inflammation, and other conditions can disrupt the NAD system, and how nicotinamide riboside (NR) compares with niacin, nicotinamide, and NMN. The conversation also covers research on exercise recovery, peripheral artery disease, skin health, infection, and wound healing, along with the limitations of current human evidence. Brenner explains why he advises against IV and subcutaneous NAD+, discusses concerns around NMN quality, and challenges popular sirtuin-centered theories of anti-aging while emphasizing the importance of reproducible human research. Charles Brenner is an NAD metabolism researcher whose work focuses on cellular bioenergetics, vitamin B3 biology, metabolic stress, and the pathways that regulate NAD production and utilization throughout the body. Now based at the University of Helsinki, his research has examined how the NAD system responds to conditions ranging from metabolic and liver disease to mitochondrial dysfunction, inflammation, and neurological stress. His work has also helped advance research into nicotinamide riboside as an NAD precursor and its potential applications in human health. Brenner takes an evidence-first approach to longevity science, distinguishing findings supported by controlled human studies from promising but still unproven mechanisms, animal research, and anecdotal claims.   Brenner Lab — Charles Brenner, PhD https://www.brennerlab.net/   Niagen NR Clinical Studies — Niagen Bioscience https://www.niagenbioscience.com/pages/clinical-studies   Nicotinamide Riboside for Peripheral Artery Disease — Mary M.

    #232 Testosterone Screening, Metabolic Health, and Hormone Optimization: Free T, SHBG, hCG, and Body Composition

    This episode explores the opportunities and risks of testosterone optimization, beginning with the US military's decision to screen men over 30 for low testosterone. Dr. Mike Hart and Dr. Jonathan Schoeff discuss why symptoms such as fatigue, low libido, and difficulty changing body composition cannot be interpreted from a single lab value. They examine the importance of free testosterone, SHBG, insulin resistance, visceral fat, estradiol, DHT, fertility, and individualized dosing. The conversation also challenges common measures such as BMI and body fat percentage, emphasizing skeletal muscle mass, visceral adiposity, sustainable health goals, and the minimum effective intervention.   Dr. Jonathan Schoeff is a spinal surgeon and longevity medicine practitioner whose work focuses on hormone health, metabolic optimization, body composition, and individualized health strategy. Through comprehensive laboratory testing, clinical assessment, and personalized treatment planning, he helps clients understand how hormones, insulin sensitivity, muscle mass, visceral fat, lifestyle, and long-term health goals interact.

    #229 Supplements, Methylation, and Genetics: Why "Healthy" Stacks Can Trigger Anxiety

    Dr. Tyler Panzner joins Dr. Mike Hart to explain how genetics, supplement combinations, and individual brain chemistry can influence anxiety, irritability, brain fog, and the persistent "monkey on your back" feeling. They examine why the MTHFR gene is scientifically valid but often overmarketed, and why methylated B vitamins, SAMe, creatine, phosphatidylcholine, and other methylation-related supplements may help some people while overstimulating others. The conversation also explores hidden "adrenaline trappers" such as quercetin, polyphenols, and greens powders; why NAC, glutathione, and high-dose antioxidants may cause unwanted effects; and how lithium orotate, melatonin, nicotine, methylene blue, omega-3s, collagen, mitochondrial enhancers, and DHT-lowering supplements can affect people differently. Dr. Panzner also discusses pharmacogenomics, SSRI response, supplement timing around exercise, the limitations of genetic testing, and the importance of combining DNA data with bloodwork, symptoms, medication history, and baseline nutrient status. Dr. Tyler Panzner is a pharmacology and genetics expert whose work focuses on personalized supplementation, genetic testing, neurotransmitter pathways, and understanding why the same health intervention can affect people very differently. Through DNA analysis, laboratory review, supplement audits, and individualized coaching, he helps clients identify which biological pathways may need support and which commonly recommended supplements may be working against them. His approach challenges one-size-fits-all biohacking and emphasizes using genetics, bloodwork, symptoms, and personal response patterns to make more informed decisions about mental health, performance, and long-term wellness.   Work with Dr. Tyler Panzner!

    #228 Minoxidil for Hair Loss: Topical vs Oral, Tretinoin, and Microneedling

    The episode explains how to use minoxidil for hair loss, emphasizing that it supports follicles and prolongs the anagen phase but does not block DHT (with topical dutasteride mentioned as a scalp-focused DHT option). It reviews evidence that 5% topical minoxidil is optimal (better than 2% and superior to 10%), works best on the crown/vertex, and should be applied to the scalp—not the hair—with expectations set for gradual results and possible early shedding. Twice-daily topical use is recommended unless combined with 0.01% tretinoin, which can make once-daily use similarly effective, though irritation can occur. Microneedling combined with minoxidil is strongly recommended based on a 2013 RCT, with guidance on depth (0.5–1.0 mm), frequency, and waiting 12–24 hours (or longer with tretinoin) before applying minoxidil. The episode also compares oral minoxidil dosing, notes a 2024 RCT showing similar outcomes to topical at 5 mg, and details systemic side effects, monitoring, and cautions including pet toxicity with topical use.   Full Hair Loss Podcast — Wnt vs DHT https://www.youtube.com/watch?v=bswq-Qhfebs   Minoxidil + Microneedling — 2013 Study https://pmc.ncbi.nlm.nih.gov/articles/PMC3746236/   5% vs 2% Topical Minoxidil https://pubmed.ncbi.nlm.nih.gov/12196747/   5% vs 10% Topical Minoxidil https://pubmed.ncbi.nlm.nih.gov/31403367/   Minoxidil + 0.01% Tretinoin Study https://pubmed.ncbi.nlm.nih.gov/17902730/   Oral vs Topical Minoxidil — 2024 Study https://pmc.ncbi.nlm.nih.gov/articles/PMC11007651/   Topical Dutasteride Study https://pmc.ncbi.nlm.nih.gov/articles/PMC12405733/   Topical Minoxidil Drug Information https://medlineplus.gov/druginfo/meds/a689003.html   Oral Minoxidil Drug Information https://medlineplus.gov/druginfo/meds/a682608.html   Tretinoin Drug Information https://medlineplus.gov/druginfo/meds/a682437.html   Dutasteride Drug Information https://medlineplus.gov/druginfo/meds/a603001.html   Minoxidil Toxicity in Dogs and Cats https://pubmed.ncbi.nlm.nih.gov/34370845/   Sildenafil / Viagra Drug Information https://medlineplus.gov/druginfo/meds/a699015.html   Tadalafil / Cialis Drug Information https://medlineplus.gov/druginfo/meds/a604008.html   Show Notes   00:00 Welcome to the Hart2Heart Podcast 00:45 Minoxidil Basics 01:43 DHT And What It Misses 03:07 How Minoxidil Works 03:55 Best Areas To Treat 04:30 Choosing The Right Strength 05:55 Once Or Twice Daily 08:28 Applying It Correctly 10:10 Microneedling Protocol 15:17 Formulations And Routine 18:14 Topical Side Effects 19:34 Shedding And Pet Safety 20:44 Oral Minoxidil Overview 22:53 Dosing And Risks 27:39 Combining Oral And Topical 28:36 Final Takeaways The Hart2Heart podcast is hosted by family physician Dr. Michael Hart, who is dedicated to cutting through the noise and uncovering the most effective strategies for optimizing health, longevity, and peak performance.

    #227 Diet Update: High-Protein, High-Fiber Meal Plan Built for Training and Consistency

    The speaker shares a structured, consistent diet designed to support hard training (three strength sessions, Norwegian 4x4, Zone 2 cardio, and one MMA session weekly), reduce "food noise," and stay full with high protein and fiber. He explains cooling/freezing rice to increase resistant starch and lower glycemic impact, then details his daily routine: a morning shake with creatine, collagen peptides, greens/red powder, and beta-alanine; four eggs mid-morning; high-protein Greek yogurt mixed with psyllium husk and acacia fiber; a pre-workout oats-and-whey bowl; a post-workout shake with whey, berries, vegetables, and sauerkraut; and a batch-prepped dinner of extra-lean ground beef, basmati rice, avocado, and sauce, plus a small yogurt-and-berries snack. Daily totals are about 2600 calories with ~260g protein, ~262g carbs, ~62–80g fat, and ~42g fiber, with weekend flexibility including two gin martinis and restaurant meals like steak or occasional pasta.   Norwegian 4x4 Protocol https://www.ntnu.edu/cerg/advice   VO2 Max / Zone 2 Cardio https://health.clevelandclinic.org/zone-2-cardio   Creatine / Athletic Performance https://ods.od.nih.gov/factsheets/ExerciseAndAthleticPerformance-Consumer/   Creatine / Sleep Deprivation Study https://pmc.ncbi.nlm.nih.gov/articles/PMC10902318/   Multi Collagen Peptides https://pmc.ncbi.nlm.nih.gov/articles/PMC8521576/   Collagen Before Exercise Study https://pmc.ncbi.nlm.nih.gov/articles/PMC5183725/   ATP Labs Greens & Reds https://atplab.com/products/green-red-whole-foods-100-organic   Beta-Alanine https://pmc.ncbi.nlm.nih.gov/articles/PMC4501114/   Coenzyme Q10 https://www.nccih.nih.gov/health/coenzyme-q10   Fish Oil / Omega-3 https://ods.od.nih.gov/factsheets/Omega3FattyAcids-Consumer/   Oikos High Protein Greek Yogurt https://www.oikos.ca/en/oikos-high-protein   Psyllium Husk / LDL Cholesterol https://www.canada.ca/en/health-canada/services/food-nutrition/food-labelling/health-claims/assessments/psyllium-products-blood-cholesterol-lowering-nutrition-health-claims-food-labelling.html   Acacia Fiber / Gut Microbiome https://pmc.ncbi.nlm.nih.gov/articles/PMC8296006/   Short-Chain Fatty Acids / Butyrate https://pmc.ncbi.nlm.nih.gov/articles/PMC8153313/   Grass-Fed Whey Protein https://atplab.com/products/grass-fed-whey   Fermented Foods / Sauerkraut https://pmc.ncbi.nlm.nih.gov/articles/PMC9020749/   Resistant Starch / Cooled Rice Study https://pmc.ncbi.nlm.nih.gov/articles/PMC9013350/   Quest Protein Bars https://www.questnutrition.com/collections/protein-bars   Show Notes   00:00 Welcome to the Hart2Heart Podcast 00:45 Diet Goals and Structure 01:58 Training Schedule and Carbs 03:42 Morning Supplements Stack 07:19 First Meal Eggs and Fats 09:00 Greek Yogurt Fiber Snack 11:26 Pre Workout Oats and Whey 13:22 Post Workout Shake and Gut Health 15:19 Dinner Meal Prep Beef Rice Avocado 18:40 Evening Snack and Sleep Timing 19:58 Daily Macros and Protein Targets 20:58 Weekend Flex Meals and Alcohol 24:30 Extra Foods and Final Takeaways 28:23 Wrap Up and Thanks   The Hart2Heart podcast is hosted by family physician Dr. Michael Hart, who is dedicated to cutting through the noise and uncovering the most effective strategies for optimizing health, longevity, and peak performance.
