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 following are just the right columns of Table 1

Autonomy and mobility are, in many cases, key elements underlying positive ageing. Vitamin D (vitD) is essential to maintaining musculoskeletal health and hence mobility; ensuring adequate vitD status is important in positive ageing. However, vitD deficiency persists in ~10–30% of older adults in the Western world. The aim of this review was to explore older adult vitD beliefs, knowledge and preferences, in order to identify means to prevent vitD deficiency respectful of older peoples’ autonomy. Academic search-engines were used to explore the research literature with the keywords: vitamin D; older adults; preferences; knowledge; practices; beliefs. 22 recent studies were identified; although the majority of older people knew of vitD, knowledge about increased fall risk secondary to deficiency was limited and knowledge did not always correlate with adequate intake or status.
There was evidence of confusion regarding vitD food sources, sun-exposure and health benefits, and although General Practitioners were trusted information sources they often did not discuss vitD with patients.
Preferences varied significantly depending on geographic location, ethnicity, socioeconomic status, education and cultural factors; overall, older people wanted more clear information about vitD.
In conclusion, older people have a relatively high awareness of vitD, however, knowledge may be inaccurate and low in those most at risk, and knowledge of deficiency-associated fall risk is under-recognised. Furthermore, studies specifically addressing older adult preferences are lacking; an understanding of preferences, integrated into public health guidelines and implementation strategies, is key not only to decreasing the risk of vitamin D deficiency but also to enabling autonomy in older adults.
