このコンテンツについて

In this episode, Dr. Ravi Kumar uncovers the powerful, misunderstood role of vitamin D in your health—and why nearly half the world is deficient. Far more than a bone vitamin, vitamin D acts as a hormone that regulates over 1,000 genes and plays a role in everything from immune function and mood to metabolism, muscle strength, and even cancer prevention. Dr. Kumar shares stories from his family, travels, and medical practice—including a powerful transformation in his grandmother’s health—to reveal the often-overlooked symptoms of deficiency and how to fix them. You’ll learn about testing, dosing, and a simple immune-boosting protocol used in his own household, along with the vital connection between vitamin D and sunlight, inflammation, and modern life. And this is just the beginning. At the end, Dr. Kumar teases the next episode on Vitamin K2, the critical cofactor that ensures vitamin D works where you need it—and not where you don’t. 🔍What You’ll Learn in This Episode Why vitamin D is both a nutrient and a hormoneHow vitamin D deficiency became a modern epidemicThe story of Tiny Tim and rickets in 19th-century citiesThe science of how sunlight creates vitamin D in the skinWhy elderly individuals often go undiagnosed with deficiencyHow low vitamin D levels affect bones, muscles, brain function, and moodWhat lab test to ask for and what levels to aim forA household protocol Dr. Kumar uses at the first sign of illnessWhy inflammation can block vitamin D activation—even with sun exposureThe optimal blood levels based on ancestral health dataWhy vitamin D alone isn’t enough for bone health without vitamin K2 🧪 Key Studies and References Explore the research behind this episode: The Impact of Vitamin D on Health and Disease - Comprehensive review of vitamin D’s role in immunity, bone health, and chronic disease.Vitamin D: A Global Perspective - Highlights global deficiency rates and the need for public health strategies.Muscle Strength and Falls in the Elderly - Study showing 72% lower fall risk in elderly patients supplemented with vitamin D.Cardiovascular Effects of Vitamin D Supplementation - Explores vitamin D’s influence on blood pressure and vascular health.Women’s Health Initiative Calcium + D Trial - Landmark study examining vitamin D, calcium, and fracture outcomes.RECORD Trial on Fracture Prevention - Randomized trial evaluating calcium and vitamin D in older adults.Vitamin D and Cancer Risk - Investigates associations between low vitamin D and increased cancer risk.The Role of Vitamin D in Autoimmune Disease - Discusses links between vitamin D levels and autoimmune conditions like MS.Vitamin D and Type 1 Diabetes Prevention - Large Finnish study showing 80% reduced risk of type 1 diabetes with early supplementation.Vitamin D and Immune System Regulation - Recent research on vitamin D’s role in innate immunity.Vitamin D and Cognitive Health - Links between low vitamin D, neurodegeneration, and cognitive decline.Vitamin D in Alzheimer’s and Dementia - Investigates protective effects of vitamin D on brain aging.Vitamin D and Mitochondrial Function - Shows how vitamin D boosts cellular energy production.Vitamin D in Obesity and Metabolic Syndrome - Highlights how vitamin D affects glucose metabolism and insulin resistance.Vitamin D Supplementation in Children - Examines outcomes of high-dose supplementation in pediatric populations.Vitamin D and Flu Prevention - Supports the idea of using vitamin D to prevent respiratory infections.Vitamin D and the Immune System – Frontiers - Open-access review on the immunomodulatory effects of vitamin D.Vitamin D and Public Health Policy – Frontiers - Policy-focused article on addressing vitamin D deficiency through food fortification and supplementation.The Role of Vitamin D in Health – A Review - Explores comprehensive biological functions and therapeutic potential.📩 Subscribe & Share If you found this episode helpful, please share it with someone who might benefit—and don’t forget to leave a review on your favorite podcast platform.
