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

OBJECTIVE:
The provision of prescribed vitamin D to all aged-care residents has been implemented in New Zealand as part of a government-led falls prevention programme. To our knowledge, there has been no evaluation of this universal programme on vitamin D status and functional and health outcomes. Thus, we aimed to determine 25-hydroxyvitamin D (25(OH)D) concentrations and their predictors in aged-care residents across the country and to investigate whether the government-funded programme was associated with adequate vitamin D status.

DESIGN:
Cross-sectional survey of sociodemographic, biochemical, anthropometric, dietary and health characteristics. Blood samples were analysed for serum 25(OH)D and other biochemical measures. Multiple regression was used to examine predictors of vitamin D status.

SETTING: Sixteen residential aged-care facilities throughout New Zealand.

SUBJECTS: Residents aged ≥60 years with residency duration >12 weeks (n 309).

RESULTS:
Mean serum 25(OH)D was 89·9 (95 % CI 85·2, 94·5) nmol/l and monthly supplements (1250 µg (50 000 IU)) were taken by 75 % of all residents. Of those not taking a funded supplement, 65·3 % had serum 25(OH)D 125 nmol/l.

CONCLUSIONS:
Residents taking supplemental vitamin D had adequate vitamin D status; however monitoring of long-term supplementation should be considered, due to the high proportion of participants with high serum 25(OH)D levels.
