The IoM math mistakes made in 2010 and admitted to in 2017 have not been yet corrected

Vitamin D math mistakes made by the IoM in 2010 – K Baggerly 2016-2017

• Mistake #1: % of cadavers with poor bones with 20-30 ng of vitamin D
  • 8%, not 1% of the people having >20 ng/ml had bone loss, so the 20 ng/ml voted level was incorrect
  • should have concluded 30 ng, not 20 ng
• Mistake #2: Not having enough data to conclude that >4,000 IU is too much (i.e. harm)
• Mistake #3: Institute of Medicine used data only for bone health, but the rest of the body needs higher levels
• Mistake #4): Incorrectly estimated dose needed to get 97.5 % of population to a vitamin D level
