10 reasons why seniors need more vitamin D

  1. Senior skin produces 3X less Vitamin D for the same sun intensity
  2. Seniors have fewer vitamin D receptors as they age
    • (The effect of low Vitamin D receptor genes does not show up on vitamin D test results)
  3. Seniors are indoors more than than when they were younger
    • not as agile, weaker muscles; frail, no longer enjoy hot temperatures
    • (if outside, stay in the shade), however, seniors might start outdoor activities like gardening, biking, etc.
  4. Seniors wear more clothing outdoors than when younger **+fear skin cancer/wrinkles, sometimes avoid bright light after cataract surgery
  5. Seniors often take various drugs which reduce vitamin D (some would not show up on vitamin D test) statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc
  6. Seniors often have one or more diseases which consume vitamin D ( osteoporosis, diabetes, MS, ...)
  7. Seniors generally put on weight at they age - and a heavier body requires more vitamin D
  8. Seniors often (40%) have fatty livers – which do not process vitamin D as well
  9. Seniors not have as much Magnesium needed to use vitamin D
    (would not show up on vitamin D test)
  10. Seniors with poorly functioning kidneys do not process vitamin D as well
    (would not show up on vitamin D test) 2009 full text online  Also PDF 2009
