Demographic patterns of total 25(OH)D (A), 25(OH)D3 (B), 25(OH)D2 (C), and C3-epi-25(OH)D3 (D) for persons aged ≥1 y: NHANES 2007–2010. Values are medians for total 25(OH)D, 25(OH)D3, and C3-epi-25(OH)D3 and 90th percentiles for 25(OH)D2; error bars denote 95% CIs. *25(OH)D2 concentrations were less than the limit of detection (i.e., <2.05 nmol/L) for participants aged 6–11 and 12–19 y.
