We explore why vitamin D3 isn’t just for bones, it’s a metabolic marker that impacts blood sugar, hormones, immunity, cardiovascular health, and brain function.
I’ll also share with you the amount that most adults need to be taking and the key cofactors to take alongside it for optimal health.

Show Highlights & Big Takeaways
1. Current Vitamin D3 Recommendations Are Far Too Low:
U.S. guidelines (600 IU/day) are based on averages meant to prevent rickets, not optimize overall health. Actual individual needs can be 8–15 times higher.
2. Vitamin D3 Is a Metabolic Marker, Not Just a Vitamin:
Vitamin D3 affects blood sugar, insulin, hormone regulation, immunity, cardiovascular health, and brain function. Low levels increase risk for type 2 diabetes, heart disease, cancer, and dementia.
3. Testing and Personalization Is Key:
Most adults benefit from 4,000–5,000 IU/day, but optimal dosage depends on body weight, skin tone, sun exposure, and health goals. Test your 25-hydroxy vitamin D levels and adjust accordingly, ensuring you also get vitamin K2 and magnesium to avoid calcium-related complications.
