6 Feb 2023 • Published on the 5th of February, 2023 Taking vitamin D supplements does not reduce the risk of asthma attacks in children or adults, according to an updated Cochrane Review. A recent study by researchers from Queen Mary University of London and the University of Edinburgh challenges the belief that vitamin D can reduce the risk of asthma attacks.
