"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."
"Asthma is a serious and sometimes life threatening disease and needs to be treated that way. Always discuss use of supplements with your allergist."
