10 reasons why seniors need more vitamin D has the following

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 when 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
11. Vitamin D is not as bioavailable in senior digestive systems (Stomach acid or intestines?)
