Vitamin D and Asthma

The lead author of the study, Manbir Sandhu, MD an allergist, suggests that, “There is a possible cause-and-effect relationship between vitamin D deficiency and uncontrolled asthma.” He went on to say, “Evidence suggests that vitamin D has a number of biologic factors that are important in regulating key mechanisms in asthma.”

The authors of the study looked back and conducted a review of the past 60 years of literature and research on the connection between Vitamin D and asthma. They found that a lack of Vitamin D is associated with increased airway hyperresponsiveness, lower lung functions, and inferior asthma control. They also found a correlation between Vitamin D deficiency and obesity, and also found it to be more common with African American populations. The authors are recommending long term clinical trials be conducted with asthma patients.

The Co-author of the study, Thomas Casale, M.D, cautioned patients that while, “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.” He recommends having a discussion with your doctor about adding Vitamin D supplements to your current treatment plan.

It’s important to discuss any changes to your health regime with your doctor, but it might be a good idea to ask them if adding Vitamin D might be helpful for you.
