Pretreatment and posttreatment levels of serum vitamin D (25D3) in patients who received vitamin D or placebo for eight weeks. Asthmatic patients with vitamin D deficiency were divided into 2 groups. 23 patients received 50,000 IU of vitamin D orally over 8 weeks, while 22 patients received placebo. Vitamin D levels were measured in the blood of these patients before and after the treatment.
