The Mitochondrial “Vitamin” from Interstellar Dust
There’s a molecule that’s been tentatively identified in the same interstellar material that forms stars and planets, yet it also shapes growth, metabolism, and cognition here on Earth. In several mammalian species,Its absence causes deficiency and it's repletion, resolution; and no, it’s not a vitamin, but should it be?Its chemistry is analogous to the combination of vitamin B2, vitamin B6 vitamin C, and its role in evolution may trace back to the very beginning of biology.00:00 – From Interstellar Dust to Human Biology01:06 – Discovery: A New Redox Co-Factor01:44 – Biological Role: Deficiency, Growth, and Evolution02:41 – Mechanisms: NAD⁺ Regeneration and Mitochondrial Signaling03:11 – Human Evidence: Cognitive and Metabolic Effects04:41 – Chemistry & Safety: Potency and Tolerability06:55 – Conclusionhttps://pmc.ncbi.nlm.nih.gov/articles/PMC8533503/

Boost Your Serotonin Naturally: The Nutrition Secret
Serotonin is often described as the “happiness molecule,” but its biology tells a larger story. Nearly every step in serotonin’s synthesis and signaling, from the transport of dietary tryptophan to the enzymes that convert it, is influenced by nutrition.This episode examines how macronutrients, micronutrients, and gut-derived metabolites shape serotonin availability across the brain and body. Protein and carbohydrate balance determine how much tryptophan enters the brain. Specific vitamins and minerals serve as essential cofactors in its production and turnover, and so on…Understanding serotonin through this nutritional lens reframes it not as a simple neurotransmitter, but as a metabolic signal connecting diet, metabolism, and mood regulation.00:00 Introduction to Serotonin01:07 Evolutionary Role of Serotonin02:08 Nutritional Influence on Serotonin Synthesis02:55 Enzymatic Pathways of Serotonin Production04:21 Macronutrients: Impact on Serotonin06:32 Vitamins and Minerals: Impact on Serotonin09:27 Plant Compounds and Gut Microbiome: Impact on Serotonin10:24 Serotonin as a Biochemical Bridgehttps://pubmed.ncbi.nlm.nih.gov/40998119/

Discovered: an amino acid that helps the gut heal itself
Every few days, your gut rebuilds itself completely - cell by cell, guided by signals we still don’t fully understand. For years, scientists have known that diet can influence this process, but the exact messenger between what we eat and how the gut heals has remained a mystery.In this episode, we look at new research from MIT that uncovers a surprising link between diet, the immune system, and regeneration in the intestine. It’s a story about how a single nutrient can activate immune cells to release molecules that tell the gut when it’s time to repair.It challenges the way we think about food, not just as fuel, but as information. Because the gut isn’t just digesting what we eat… it’s listening.00:00 Introduction to Gut Regeneration00:56 The Role of Amino Acids in Gut Health02:07 ???: A Key Player in Gut Regeneration02:35 MIT's Groundbreaking Research 03:49 The Immune System's Role in Gut Regeneration05:51 Dietary Sources and Implications 07:07 Conclusion: The Gut's Adaptive NaturePMID: 41034585

Creatine’s Role in Mitochondria is Bigger Than You Thought
Creatine’s story has been far too small for its biology. Most people still see it as a supplement for strength or cognitive performance, but its most important work happens inside the mitochondria.In this episode, we explore a side of creatine few people talk about: how it may function as mitochondrial medicine. We’ll break down 3 distinct ways creatine acts in and supports the mitochondria; roles that could reshape how we think about energy, resilience, and cellular health. And beyond that, how creatine may be one of the few molecules that can both diagnose and treat mitochondrial dysfunction. 00:00 Understanding Mitochondrial Dysfunction00:43 Introduction to Creatine's Role01:16 Mitochondrial Dysfunction Explained01:56 Creatine as a Theranostic Agent02:57 Mechanisms of Creatine in Mitochondria04:09 Therapeutic Roles of Creatine05:22 Redox Control and Antioxidant Properties06:27 Conclusion: The Unique Power of Creatine PMID: 40948982

Polyphenols Are Doing Something No One Expected
In this episode of The Daily Value, we look at new research suggesting that polyphenols might be doing something we never expected — not just acting as antioxidants, but organizing themselves into microscopic structures that can stabilize the very proteins that keep our cells alive. It’s a discovery that could reshape how we think about plant compounds and resilience at the molecular level. We explore how this structural behavior gives new meaning to the idea that diversity matters in our diet — and why the age-old advice to “eat the color spectrum” may be more scientifically accurate than anyone realized.00:00 – The Flavonoid Paradox: Quantity vs. Diversity01:12 – What Are Polyphenols Really Doing in the Body?02:16 – Diversity as a Predictor of Longevity and Disease Risk03:17 – Beyond Antioxidants: A New Molecular Hypothesis03:58 – Self-Assembling Flavonoids and Protein Stabilization05:45 – Mechanistic Insight: How Molecular Networks Support Cellular Resilience09:45 –The Science Behind “Eat the Color Spectrum”

Lead Exposure from Protein Supplements Explained
In this episode of The Daily Value, we examine Consumer Reports’ October 2025 findings on lead in protein powders. The investigation tested 23 products and found that more than two-thirds exceeded the organization’s internal lead safety threshold. We discuss what those results mean in biological terms, how regulatory limits differ between the FDA, EFSA, and Health Canada, and how supplement exposure compares to everyday dietary intake.00:00 Introduction00:08 Consumer Reports Investigation Finds Lead in Protein Powders01:07 Understanding Lead Contamination in Protein Powders03:00 Health Implications of Lead Exposure06:41 Regulatory Standards and Safety Thresholds09:30 Comparing Lead Intake from Food and Supplements15:56 Practical Advice and Final Thoughtshttps://efsa.onlinelibrary.wiley.com/doi/abs/10.2903/j.efsa.2010.1570https://www.fda.gov/food/fda-total-diet-study-tds/fda-total-diet-study-tds-resultshttps://www.consumerreports.org/lead/protein-powders-and-shakes-contain-high-levels-of-lead-a4206364640/https://wwwn.cdc.gov/Tsp/ToxProfiles/ToxProfiles.aspx?id=96&tid=22

Women and Alzheimer’s: A New Lead
Why are nearly two-thirds of Alzheimer’s patients women? For decades, the explanation seemed simple: women live longer. But the numbers don’t add up. Even after 80, when survival rates even out, women are still more likely to be diagnosed. A new lead may finally expose what’s been hiding in sex-specific biology.00:00 Introduction: The Alzheimer's Gender Imbalance00:05 Uncovering Biological Clues01:39 The Role of Lipid Metabolism02:47 New Study Sheds Light03:49 Detailed Findings on Lipid Patterns09:43 Implications for Future Research and Treatment12:12 Conclusion: A New Lead in Alzheimer's ResearchPMID: 40832908

The Case of the Missing Molecules
Parkinson’s disease has long been defined by the death of neurons in the brain. Yet, decades before tremors appear, the first signs emerge quietly in the gut. Recent evidence reveals a puzzling disappearance: microbial pathways that once produced two well-known compounds fall silent. Their absence strips away protective metabolites, erodes the intestinal barrier, and leaves neurons exposed to toxins that ignite α-synuclein fibrils. Could the vanishing of two simple vitamins be an overlooked trigger, and a potential target, in the unfolding mystery of Parkinson’s disease?00:00 Introduction to Parkinson's Disease00:35 Early Signs and Gut Connection01:19 The Braak Hypothesis and Vagus Nerve02:08 Gut Microbiome and Vitamin Pathways03:10 Global Meta-Analysis and Key Findings04:37 Impact of Vitamin Deficiencies08:57 Potential for Vitamin Supplementation11:20 Conclusion and Future ImplicationsPMID: 37314861

Two Compounds That Recharge Aging Neurons
In the aging brain, neurons begin to lose a hidden currency. Not just ATP, but GTP - that powers their ability to clear away toxic proteins. Without it, the cleanup crews stall, and amyloid builds up. A team at UC Irvine may have uncovered a way to recharge that system using two familiar compounds. In aged and Alzheimer’s model neurons, this pairing restored GTP, reactivated trafficking pathways, and swept away protein aggregates. In this episode, we follow the trail from dwindling cellular energy to revived cleanup machinery, and explore how these findings fit with human evidence.00:00 Introduction: The Overlooked Clue in Aging Brains00:47 The Energy Crisis in Aging Neurons01:21 Natural Compounds to the Rescue01:55 The UC Irvine Study: A Closer Look03:05 Mechanisms Behind Nicotinamide and EGCG04:37 Human Data: What Do We Know?06:59 Comparing Strategies: Drugs vs. Natural Compounds08:11 Challenges and Future Directions09:27 Conclusion: A Promising but Unproven StrategyPMID: 40661491
