Vitamin D may reduce risk of severe asthma attacks

Taking vitamin D supplements could significantly reduce the risk of severe asthma attacks for some asthmatics, health experts have found.

Asthma patients who suffer from severe attacks, or exacerbations, were at a lower risk of having an attack and less likely to need hospital treatment if they had been taking regular doses of the vitamin, trials carried out by a Cochrane Review showed.

They were also less likely to need treatment with steroid tablets.
