Vitamin D for the management of asthma.

Abstract596035-1366x768-[DesktopNexus.com]

Background: Several clinical trials of vitamin D to prevent asthma exacerbation and improve asthma control have been conducted in children and adults, but a meta-analysis restricted to double-blind, randomised, placebo-controlled trials of this intervention is lacking.

Authors’ conclusions: Whilst we are confident that Vitamin D reduced the risk of asthma exacerbation in these trials (high quality GRADE assessment), we recognise that there is uncertainty about how these findings might be applied in practice. More research is needed to clarify whether there is a difference in effect between adults and children and with respect to asthma severity, baseline vitamin D status and doses.
