I purchased the NEJM paper ($20) which dozens of websites were reporting on
Report content was virtually identical due to copying from a NEJM news release.
Example titles include

  • Too many people are worried about vitamin D deficiency, experts say
    "Only 13 percent of Americans aged 1 to 70 are at risk of being deficient in vitamin D — and less than 6 percent are deficient."
  • Vitamin D deficiency is widely overestimated, doctors warn"
  • Vitamin D deficiency may be widely overestimated
  • Doctors warn about overdosing on Vitamin D
  • Don’t Worry About Getting More Vitamin D, Doctors Reassure
  • Why you probably don't need more Vitamin D
  • Too many people are being told they have a vitamin D deficiency

The paper cannot be posted on the web - The paper is behind a $20 paywall

My comment
They think that 600 IU will provide 97% of the non-seniors (including obese, pregnant, dark skinned, etc) with enough Vitamin D (for bone health). They believe that 97% of non-seniors need LESS than 20 ng (for bone health)

"Less than 6% are deficient in vitamin D [serum 25(OH)D levels <12.5 ng per milliliter"
   Their reference is the IoM report - that data for which is now 8 years out of date

Here are a few papers papers which strongly disagree

  • Bone fractures reduced by a minimum of 800 IU vitamin D and Calcium – meta-meta-analysis March 2014

  • Bone health best with 40 nanograms of vitamin D – Oct 2015
