  • ..."implemented nationwide in New Zealand by 2011"
  • ..."recommends a loading dose of 2500 µg (100 000 IU) cholecalciferol (vitamin D3) in the first month followed by a maintenance dose of 1250 µg (50 000 IU) monthly thereafter for life"
  • no Vitamin D testing - offered to all
  • "Overall our study shows that the uptake of the government-funded vitamin D supplementation programme was high, with three-quarters of participants receiving monthly vitamin D supplementation, ..."
  • ". In the present study, we did not collect information regarding the incidence of falls or fractures and thus cannot determine the impact of the supplementation programme on skeletal outcomes"

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
  6. Seniors often have one or more diseases which consume vitamin D
  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?)

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.

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).

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.

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.
