A massive statistical error has kept vitamin D recommendations 15 times too low for decades.
- Official recommendation: 600 IU/day
- Actually needed: 8,895 IU/day
A peer-reviewed study calculated that 8,895 iu/day is required for 97.5% of people to reach adequate vitamin D levels… not 600 IU/day.
The institute of medicine accidentally or intentionally “confused” group averages with individual requirements.
