This is a pilot randomized controlled trial of lower vs. higher dose vitamin D supplementation in D-deficient asthmatic children, to determine necessary sample sizes for outcome measures in a larger multisite study, and to examine possible relationships and effect sizes between various biological markers that may be important to the pathophysiology of childhood asthma. Aims of the study are to: Evaluate effect sizes for relationships between serum 25OH-vitD and omega-fatty acid (FA) biomarkers, before and after supplementation with lower or higher dose vitamin D, on immune function, and asthma severity. Characterize changes in innate and adaptive immune function and inflammatory responses in asthmatic D-deficient youth at baseline and after vitD supplements, by dietary O6:O3FA status and vitD dose.
