Overview Seniors and Vitamin D

Just 2 cents a day of vitamin D:

  • reduces falling and fractures,
  • improves cognition,
  • decreases chance of Alz and Parkinson’s,
  • increases chance of surviving hospital,
  • Improves balance,
  • reduces muscle loss,
  • reduces flu,
  • reduces need for antibiotics,

From 10 reasons why seniors have low levels of 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 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?)

In addition, some seniors are low because they are:

- Living in Northern latitudes and do take a winter trip to a sunny area in the winter
- Overweight
- Dark skinned
- Had recent surgery/trauma

Falls and Fractures
Many studies have proven that increasing vitamin D decreases falls and fractures.
By several mechanisms

  • 1) improve reaction time
  • 2) Improve muscle,
  • 3) increase bone density

There are not just association of low vitamin D and falling/fractures, but scores of actual random controlled trials – from all around the world

Seniors and Fraility

Seniors and Cognition

Seniors and Depression

Also many papers showing that Vitamin D greatly decreases winter flu and colds
– which occur at the time that vitamin D blood levels are lowest. (4+ months away from time in the sun)
Dosing CLICK HERE for Overview How much D__
Some Doctors are starting with very high single doses to stop being deficient as soon as possible
Try a small dose first. I am concerned that this does not allow for possible reactions to vitamin D which can be tested by taking a much smaller amount for a week or so. Only a tiny fraction of the population is allergic to vitamin D3, but I feel that it is better to check first before plunging in.
Consider using vitamin D before surgery.
A variety of studies show D3 does not work much below 1200 IU / day, perhaps even less for D2
Some studies show that vitamin D thwarted by vitamin A

Loading Dose = how much to start with to recharge = Stoss Therapy

Should take bone supplement along with Vitamin D – but only 500 to 750 milligrams of Calcium– see supplements section and graph
Category Supplementing D    Calcium    Magnesium
OK to take vitamin D when have Cancers – seems to even help prevent some cancers. Might treat a few.– see Cancer file gallery

Half of seniors did not respond to 1600 IU of vitamin D daily for a year
