415: Why Vitamin D Is Actually a Longevity Hormone (Not a Vitamin)

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.
On this episode, you’ll learn:
- Why vitamin D isn’t actually a vitamin (01:11)
