Vitamin D supplements along with standard medication may halve the risk of suffering a severe asthma attack requiring hospital attendance, a study claims. The study, conducted by Researchers from Queen Mary University of London (QMUL), found that vitamin D supplementation resulted in a 30 percent reduction in the rate of asthma attacks requiring treatment with steroid tablets or injections. <br/><br/>Researchers also found that the supplementation resulted in a 50 per cent reduction in the risk of experiencing at least one asthma attack requiring hospitalisation – from six percent of people experiencing such an event to three per cent. <br/><br/>Lead researcher, Adrian Martineau, professor at QMUL said these results add to the ever growing body of evidence that vitamin D can support immune function as well as bone health. '<br/>'<br/><br/>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, Rsearchers said.
