Episode notes
Vitamin D Is A Prohormone, Not The Active Agent
- Vitamin D itself is inactive and must be converted to 25-hydroxyvitamin D and then to calcitriol to work.
- Blood tests measure 25-hydroxyvitamin D, not the active calcitriol form, so tests don't show full activity.
Aging Lowers Vitamin D Activation And Response
- Aging reduces both the enzyme that activates vitamin D and the number of vitamin D receptors in tissues.
- As a result, older people convert and respond less to vitamin D, changing dose needs over time.
Test First, Then Tailor Your Dose
- Start with about 4,000–5,000 IU daily then retest after two months to see your blood 25(OH)D level.
- If levels are below ~40–50 ng/mL increase dose; adjust until you find your genetic/age sweet spot.
