25-hydroxyvitamin D: the public record
Each table is computed from the named federal dataset as of its data date; the method is under each one.
Population data
How 25-hydroxyvitamin D is distributed in US adults

| Men 40 to 59, median | 69.1 nmol/L | middle 90% of people: 26.8 to 126; 717 people tested |
| Men 60 and over, median | 84.3 nmol/L | middle 90% of people: 39.1 to 149; 1,193 people tested |

How this was calculated
Computed survey-weighted 5th, 50th and 95th percentiles from the CDC public file by sex and age band, using the sample weight WTPH2YR. Groups with fewer than 50 people are left out.
US adults aged 20 and over who gave a sample in NHANES 2021 to 2023, CDC variable LBXVIDMS (25OHD2+25OHD3 (nmol/L))
These are population distributions, not clinical reference ranges or treatment targets. They include people with and without health conditions and people on medication. Laboratories differ in method and units.
