Vitamin D Meeting in Washington DC

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

Dec 2, 3 2014

Summary notes by Vitamin D Life

  • 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
