Researchers in Israel have found that vitamin D could help people to manage asthma attacks.
The study, published in the journal, Allergy, was based on the analysis of the medical records of almost 4 million adults in Israel. Of these people, over 300,000 had had their vitamin D levels tested between 2008 and 2012, and, of this group of people, 21,000 had separately been diagnosed with asthma.
The researchers found that, of these 21,000 people with asthma, those lacking in vitamin D were 25% more likely than others to have recently had an asthma attack.
Based on their results, the researchers recommend that people with difficult-to-control asthma should have their vitamin D levels tested. If people are found to have low levels, supplements may be useful to address this.
