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
       Seniors category has 428 items

Highlights

  • More people were at risk for low vitamin D status after standardization of serum 25(OH)D values.
  • Associations between serum 25(OH)D and physical functioning, falls and fractures were similar after standardization.
  • Larger differences between original and standardized serum 25(OH)D values were observed in some other cohorts.
  • Standardization is of utmost importance for reaching consensus in clinical cut-offs.

The Longitudinal Aging Study Amsterdam (LASA) is an ongoing prospective cohort study in a representative sample of Dutch older persons. In previous LASA studies, lower serum 25-hydroxyvitamin D (25(OH)D) values, as assessed by a competitive protein binding assay or radioimmunoassay, have been associated with decreased physical functioning, falls and fractures. Recently, serum 25(OHD) values in LASA were standardized using the Vitamin D Standardization Program (VDSP) protocol as part of the European ODIN project. In the current manuscript, the influence of standardizing serum 25(OH)D values will be discussed using the associations with physical functioning, falls and fractures as examples.
