Eligibility
Inclusion criteria
* Physician diagnosed asthmatics and they should fulfill at least two of the following three criteria: * A minimum of three clinic visits for acute asthma within 1 year * Two or more asthma-related hospital admissions within 1 year, or * Steroid dependency, as defined by either 6 months of oral or 1 year of inhaled corticosteroid use * Age: 6-14 years old. The age group of 6 to 14 years old was chosen for two reasons: 1. Diagnostic accuracy of asthma is better in this age group as non-specific wheezers less than 6 years of age could be excluded. 2. Child should be able to use a peak flow meter and perform spirometry tests. * A positive specific IgE or a positive skin prick test for at least one airborne allergen.
Exclusion criteria
* Children with mild intermittent and mild persistent asthma. * Asthmatic children who are currently on immunotherapy or anti IgE. * Asthmatic children with concomitant other medical problems. * Children who are younger than 6 yrs or older than 14 yrs. * Children with history of early life injury to airways like premature birth (\< 36 weeks) or home use of oxygen. * Children with vitamin D deficiency. Since these children may be randomized to the control group, they will be excluded for ethical reasons.
