Dietary reference intakes for calcium and vitamin D
Institute of Medicine (IOM) · 2011
What this work gives Aellic
Practically all persons are sufficient for bone health at a serum 25-hydroxyvitamin D of 50 nmol/l (20 ng/ml) or more; there may be reason for concern above 125 nmol/l (50 ng/ml).
Correction of 25 October 2026
The registry tied “at least 97.5 percent of the population” to the serum level of 50 nmol/l. In the report 97.5 percent defines the intake recommendation (RDA); for the serum level it says that practically all persons are sufficient at 50 nmol/l or more.
The entry on the register was wrong. It was not replaced but kept, with what holds instead standing next to it.
Where this sits in the engine
This work is on the register, but nothing computes with it today, mostly because the feature it belongs to has not been built yet. It is listed so the numbers on the overview do not claim more than they carry.
