13 reasons why many seniors need more vitamin D (both dose and level) - July 2023

  1. Senior skin produces 4X less Vitamin D for the same sun intensity
  2. Seniors have fewer vitamin D receptor genes as they age
    Receptors are needed to get Vitamin D in blood actually into the cells
  3. Many other Vitamin D genes decrease with age
  4. Since many gene activations are not detected by a blood test,
    more Vitamin D is often needed, especially by seniors
  5. Seniors are indoors more than when they were younger
    not as agile, weaker muscles; frail, no longer enjoy hot temperatures
  6. Seniors wear more clothing outdoors than when younger
    Seniors also are told to fear skin cancer & wrinkles
  7. Seniors often take various drugs which end up reducing vitamin D
    Some reductions are not detected by a vitamin D test of the blood
    statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc
  8. Seniors often have one or more diseases that consume vitamin D
    osteoporosis, diabetes, Multiple Sclerosis, Cancer, ...
  9. Seniors generally put on weight as they age - and a heavier body requires more vitamin D
  10. Seniors often (40%) have fatty livers – which do not process vitamin D as well
  11. Reduced stomach acid means less Magnesium is available to get vitamin D into the cells
  12. Vitamin D is not as bioavailable in senior intestines
  13. Seniors with poorly functioning kidneys do not process vitamin D as well

Skin of seniors generates less Vitamin D

Elderly skin generates less vitamin D
Wonder what % of the "diseases of aging" are due to low vitamin D?

The Blue Zone books show seniors in their 90's who are active in gardens (getting lots of vitamin D - as well as exercise, good food, etc.)
