HHS HealthBeat (June 4, 2014)

Vitamin D and asthma

From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

Vitamin D is good for bones – and some diseases in which there is inflammation. Asthma is such a disease – but a study that tested whether vitamin D supplements would help has found they do not.

At Washington University School of Medicine in St. Louis, researcher Mario Castro looked at 28 weeks of data on over 400 people with asthma and low vitamin D. About half took vitamin D; the rest took an inactive substitute.

“There was no effect on asthma control, and this was whether or not we looked at asthma exacerbations, or their symptoms, or their control of their asthma. All of those things were not affected by replacing their vitamin D.”

The study in the Journal of the American Medical Association was supported by the National Institutes of Health.
