New research has found evidence from randomized trials, that taking an oral vitamin D supplement in addition to standard asthma medication is likely to reduce severe asthma attacks. Asthma is a common chronic disease affecting about 300 million people worldwide. The symptoms of asthma include wheezing, coughing, chest tightness and shortness of breath. Low blood levels of vitamin D have been linked to increased risk of asthma attacks in children and adults with asthma. There has been a growing interest in the potential role of vitamin D in asthma management because it might help to reduce upper respiratory infections, (such as the common cold) that can lead to exacerbations of asthma. Several clinical trials have tested whether taking vitamin D as a supplement has an effect on asthma attacks, symptoms and lung function in children and adults with asthma.
