Estimated dietary vitamin D requirement percentiles (IU/day)^*

25(OH)D cutoff	50^th	90^th	95^th	97.5^th
≥12 ng/mL	--^**	581 (340, 785)	877 (635, 1151)	1137 (856, 1493)
≥16 ng/mL	10.6 (−357, 221)^†	1062 (854, 1330)	1359 (1092, 1744)	1618 (1290, 2110)^†
≥20 ng/mL	489 (288, 657)	1543 (1269, 1973)	1840 (1494, 2404)^†	2098 (1685, 2781)^†

Estimates (95% bootstrap CI) are based on a model of serum 25(OH)D as a function of vitamin D intake, race, and pubertal status and 10,000 bootstrap replicates.

^†

Cells contain results extrapolated beyond the observed quantities of daily vitamin D intake.

^**

Data does not support estimating the required intake of vitamin D intake for 25(OH)D cutoff of ≥12 ng/mL in 50% of the study cohort.
