How Much Vitamin D You REALLY Should Be Taking | EP 415

from The Dr. Gundry Podcast

I once had a patient tell me, "You don't know much about vitamin D, do you?" He had a point, not because I hadn't studied it, but because so much of what we're taught about vitamin D simply hasn't caught up to the research.My patient’s question  led me down a path of research that changed how I treat every patient who walks through my door.In this episode, I break down Why vitamin D isn't a vitamin at all but a hormone quietly running the show for your gut and immune system Why the "toxic" dose you've been warned about is a myth that's kept millions of people needlessly deficient Why this one hormone might be the closest thing we have to a longevity switch.Plus, learn the exact number I push my own patients' levels to, and why your doctor's idea of "normal" is probably way too low.For full show notes and transcript: drgundry.com/how-much-vitamin-d-should-i-takeOn this episode, you’ll learn:  Why vitamin D isn't actually a vitamin (01:11)How nearly 80% of new patients turn out to be vitamin D deficient (you probably are too!)
