Episode notes
Prefer Sun-Derived Vitamin D Over Supplements
- Get vitamin D primarily from sunlight rather than routine oral supplementation to preserve natural receptor regulation.
- Avoid synthetic high-dose vitamin D supplements that can dysregulate RXR/VDR-mediated signaling.
Check D Synthesis, Not Just 25-OH Levels
- Test earlier steps of vitamin D synthesis (like 7-dehydrocholesterol) instead of only 25-OH D to assess true production.
- Recognize liver and kidney roles and that urban EMF may downregulate megalin and impair conversion.
Daily Light Hygiene And EMF Reduction
- Watch sunrise daily, replace LEDs, avoid sunglasses and sunscreen, and spend time outdoors to rebuild melanin and circadian signaling.
- Reduce EMF exposure, use wired internet, and avoid carrying phones on your body to protect germline and fertility.
