Researchers at Copenhagen University Hospital and the University of Copenhagen looked at 4,092 people between the ages of 24 and 77. Participants had their lung function tested.

Participants also had blood tests to measure vitamin K levels in their blood and answered questions about their overall health and lifestyle.

The results showed that people with low vitamin K levels had a lower volume of air they could inhale or exhale in one second. These people were also more likely to have chronic obstructive pulmonary disease, asthma or wheezing, according to the New York Post.

The results suggest that vitamin K may play an important role in keeping the lungs healthy, said study author Dr Torkil Jespersen.

Dr Apostolos Bossios, secretary of the European Respiratory Society for respiratory diseases, asthma, COPD and chronic cough, also said: This study shows that people with low blood levels of vitamin K may have poorer lung function.
