Most recently, a NEJM paper “Vitamin D Deficiency \u2014 Is There Really a Pandemic?<\/a>” by Manson, Brannon, Rosen, and Taylor explains the big\u00a0misunderstandings that let some authors conclude that whole populations are being vitamin D deficient. Just to recall, the IOM recommended in 2010 serum concentrations of vitamin D (i.e., 25-hydroxyvitamin D\u00a0[25(OH)D]) above 20 ng per milliliter<\/em> (or 50 nmol per liter) as appropriate level and supplementation with 600 to 800 IU per day<\/em> as Recommended Dietary Allowance (RDA).\u00a0And here are the 8\u00a0facts:<\/p>\n

    \n
  1. The RDA reflects the estimated requirement for people at the highest end of the distribution. Practically everyone in the population (at least 97.5%, or within 2 SD of the median) will have a requirement below the RDA!<\/li>\n
  2. The RDA assume minimal to no sun exposure!<\/li>\n
  3. The RDA does NOT provide a \u201ccut point\u201d! It is NOT true that the entire population must have a serum 25(OH)D level above 20 ng per milliliter to achieve good bone health.<\/li>\n
  4. According to NHANES data, less than 6% of US Americans are deficient in vitamin D serum levels!<\/li>\n
  5. The relationship between serum 25(OH)D and PTH is inconsistent, and no clear threshold defining \u201csufficiency\u201d has been established!<\/li>\n
  6. Vitamin D is a hormone of concern, but current levels of deficiency do not constitute a pandemic!<\/li>\n
  7. There is also a tolerable Upper Intake Level for vitamin D intake with adverse effects! It has been set by the IOM to 4000 IU daily with a resulting serum 25(OH)D concentration of approximately 50 ng per milliliter (125 nmol per liter).<\/li>\n
  8. For otherwise healthy patients (except osteoporosis, osteomalacia, malabsorption, use of anticonvulsants, institutionalization), routine screening is not recommended!<\/li>\n<\/ol>\n
