Vitamin D helps with non-cancer as well

Proof that Vitamin D Works 60+ diseases other than Cancers
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
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
   • Seniors also are told to fear skin cancer/wrinkles
5. Seniors often take various drugs which reduce vitamin D
   • Some reductions 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. Reduced stomach acid ==>less Magnesium needed to utilize 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?)
