Vitamin D may Offer Relief to Asthma Sufferers

Vitamin D may offer relief to those suffering from asthma, according to experts. 
"There is a possible cause-and-effect relationship between vitamin D deficiency and uncontrolled asthma," said allergist Manbir Sandhu, lead author and ACAAI member.
"Evidence suggests that vitamin D has a number of biologic factors that are important in regulating key mechanisms in asthma." 
Authors conducted a review of almost 60 years of literature on vitamin D and asthma. According to the article, vitamin D deficiency is associated with increased airway hyperresponsiveness, lower lung functions, and inferior asthma control. 
Vitamin D deficiency is more common with obesity, in African American ethnicity and westernization of countries reflecting a higher-risk population for asthma. The authors recommend that long-term interventional trials be conducted in asthma patients. 
Co-author: "Vitamin D can complement your prescribed asthma treatment plan as it has been shown to have some anti-inflammatory properties, but should never be used as an alternative to prescribed medication."
