Vitamin D helps with non-cancer as well

Proof that Vitamin D Works 60+ diseases other than Cancers
13 reasons why many seniors need more vitamin D (both dose and level) - July 2023 has the following

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
14. Glutathione (which increases Vitamin D getting to cells) decreases with age
