Vitamin D Meeting in Washington DC - Dec 2014

Vitamin D: Moving Toward Evidence-based Decision Making in Primary Care

Dec 2, 3 2014
Summary notes by VitaminDWiki

  • There may be a problem for vitamin D levels > 50 ng
  • People need a lot more vitamin D than they are getting
  • Controversey as to how much - little conversation about basing dose size on weight
  • Groups who are at high risk of being deficient - they acknowledge only elderly, blacks, excessive clothes so far
  • Testing inaccuracy continues to be a big problem
  • Blacks need a lower level than whites - continues to be a controversy
  • Genes are important, and vitamin D deficiency can be inherited
  • Virtually no discussion on importance of cofactors
