Vitamin D Supplementation Provides No Help In Asthma Treatment

May 19, 2014: 12:00 AM EST
Data collected in previous studies have led scientists to wonder whether supplementation for those who are vitamin D deficient might, in conjunction with other therapies, help improve airway conditions in asthmatics.  A U.S. study tested the theory among 400 asthmatic adults who received either vitamin D (with a corticosteroid) or a placebo.  Researchers found no association between the two: vitamin D3 plus ciclisonide did not reduce the rate of treatment failure. Indicators of failure included the need for increased steroids or a worsening of asthma symptoms. They also found no significant reduction in other outcomes related to asthma control, such as airway function, quality of life, or airway inflammation.
