Background: Dark skin and low exposure to sunlight increase the risk of vitamin D insufficiency in children. Objective: The aim of the study was to evaluate the amount of vitamin D needed to ascertain that most children >4 y of age attain sufficient serum25-hydroxyvitamin D [S-25(OH) D; i.e., >= 50 nmol/L] during winter regardless of latitude and skin color. Design: In a longitudinal, double-blind, randomized, food-based intervention study, 5- to 7-y-old children from northern (638 degrees N) and southern (558 degrees N) Sweden with fair (n = 108) and dark (n = 98) skin were included. Children, stratified by skin color by using Fitzpa-trick's definition, were randomly assigned to receive milk-based vitamin D-3 supplements that provided 2 (placebo), 10, or 25 mu g/d during 3 winter months. Results: Mean daily vitamin D intake increased from 6 to 17 mu g and 26 mu g in the intervention groups supplemented with 10 and 25 mu g, respectively. In the intention-to-treat analysis, 90.2% (95% CI: 81.1%, 99.3%) of fair-skinned children randomly assigned to supplementation of 10 mu g/d attained sufficient concentrations, whereas 25 mu g/d was needed in dark-skinned children to reach sufficiency in 95.1% (95% CI: 88.5%, 100%). In children adherent to the study product, 97% (95% CI: 91.3%, 100%) and 87.9% (95% CI: 76.8%, 99%) of fair-and dark-skinned children, respectively, achieved sufficient concentrations if supplemented with 10 mu g/d. By using 95% prediction intervals for 30 and 50 nmol S-25(OH) D/L, intakes of 6 and 20 mu g/d are required in fair-skinned children, whereas 14 and 28 mu g/d are required in children with dark skin. Conclusion: Children with fair and dark skin require vitamin D intakes of 20 and 28 mu g/d, respectively, to maintain S-25(OH) D >= 50 nmol/L, whereas intakes of 6 and 14 mu g/d, respectively, are required to maintain concentrations >= 30 nmol/L during winter.
