JAKARTA - Vitamin K plays an important role in several body functions such as blood clots, bone strength, and heart health. A recent study reveals that low levels of vitamin K can cause lung health problems.

A team of researchers from the Copenhagen University Hospital and Copenhagen University found that people with inadequate levels of vitamin K in the body are prone to asthma, chronic obstructive pulmonary disease (PPOK), and wish.

The study evaluated 4,092 participants, aged 24 to 77, who carried out lung function tests, blood samples, and answered questionnaires about their health and lifestyle. People with low vitamin K levels have a lower volume of forced ekspiration (the amount of air exhaled in one second) and lower forced vital capacity (the amount of air inhaled in one forced breath).

Vitamin K has an important role in blood and research is starting to show that it is also important in heart and bone health, but there are few studies that observe both vitamin K and lung. As far as we know, this is the first study of vitamin K and its lung function in a large general population. Our results show that vitamin K can play a role in maintaining the health of our lungs," said study leader Dr. Torkil Jespersen in a media release, reported by Medical Daily, Monday, August 21.

"By itself, our findings do not change the current recommendations for vitamin K intake, but other experts suggest doing a lot of research on whether some people, such as those with lung disease, can benefit from vitamin K supplementation," added Jespersen.

Meanwhile, researchers are conducting separate large-scale clinical trials to evaluate the effects of vitamin K supplementation on heart and bone health. Based on current studies, they also plan to evaluate its impact on lung function.

This study shows that people with low vitamin K levels in their blood may have a worse lung function. Further research will help us understand more about this relationship and see if increased vitamin K can improve lung function or not. Meanwhile, we can all try to eat healthy and balanced foods to support our overall health, and can protect the lungs by not smoking, exercising and doing everything we can to reduce air pollution," said Dr. Apostolos Bossios, secretary of the European Association of Respiratory Association for respiratory disease, asthma, COPD, and chronic cough of the Karolinska Institute in Sweden.
