Daily vitamin D supplements lowered the risk and severity of asthma attacks according to a new review of some clinical trials.
Reviewers found that oral Vitamin D ranging from 400 to 4000 units a day reduced the risk of attacks requiring medication by 37% and the number of attacks requiring emergency intervention decreased by more than 60%.
The authors suggest that Vitamin D triggers anti-viral and anti-inflammatory responses that might decrease the risk for lung infection.
