Episode notes
Vitamin D Is A Hormone, Not A Vitamin
- Vitamin D is actually a powerful steroid hormone, not a typical dietary vitamin.
- It is produced in skin when UVB converts 7-dehydrocholesterol into cholecalciferol then activated by liver and kidney.
Pair Vitamin D With K2 For Safety
- When raising vitamin D, consider adding vitamin K2 to help direct calcium into bones.
- K2 activates proteins that reduce arterial and kidney calcium deposition caused by higher D-driven absorption.
Vitamin D Receptors Are Everywhere
- Vitamin D receptors exist across many tissues beyond bone, including immune and reproductive organs.
- This widespread VDR presence suggests vitamin D influences immunity, cancer, and many organ systems.
