Washington D.C. [USA], Oct 03 (ANI): Taking oral vitamin D supplements in addition to standard asthma medication">asthma medication can half the risk of asthma attacks">asthma attacks, in people with mild to moderate asthma, reveals a recent study.
Asthma deaths arise primarily during episodes of acute worsening of symptoms, known as attacks or 'exacerbations', which are commonly triggered by viral upper respiratory infections.
According to Queen Mary University of London researchers, vitamin D is thought to protect against such attacks by boosting immune responses to respiratory viruses and dampening down harmful airway inflammation.
They analysed 955 participants in seven randomised controlled trials, which tested the use of vitamin D supplements.
Lead researcher Adrian Martineau said that results add to the ever growing body of evidence that vitamin D can support immune function as well as bone health.
These participants saw a 55 per cent reduction in the rate of asthma exacerbations requiring treatment with steroid tablets or injections - from 0.42 events per person per year to 0.19.
