Low Vitamin K Linked to Reduced Lung Function and Respiratory Conditions: Study
People who have low levels of vitamin K in their blood may be more susceptible to reduced lung function and respiratory issues like asthma, chronic obstructive pulmonary disease (COPD), and wheezing, according to a recent study published in ERJ Open Research. The study, conducted by Danish researchers from Copenhagen University Hospital and the University of Copenhagen, involved 4,092 participants ranging from 24 to 77 years of age.
Vitamin K, found in leafy green foods, vegetable oils, and cereal grains, is primarily known for its role in blood clotting and wound healing. However, its impact on lung health remains largely unexplored. The researchers discovered that individuals with low levels of vitamin K exhibited lower forced expiratory volume (FEV1) and forced vital capacity (FVC) on average. Additionally, these individuals were more likely to report having COPD, asthma, or wheezing.
Dr. Torkil Jespersen, one of the researchers, acknowledged that while the study’s findings do not currently warrant a change in vitamin K recommendations, they do highlight the need for further research. It is crucial to determine whether certain individuals, such as those with lung disease, could benefit from vitamin K supplementation.
Building on their findings, the research team is undertaking a large clinical trial called the InterVitaminK trial. The trial will compare the effects of vitamin K supplementation with a placebo to examine potential impacts on heart and bone health within the general population. As a result of their recent findings, the trial will now incorporate an analysis of lung function.
Dr. Apostolos Bossios from Karolinska Institutet in Sweden, who was not part of the research team, emphasized the significance of the study’s findings. He stated that individuals with low levels of vitamin K may experience poorer lung function and underscored the importance of further research to determine if increasing vitamin K intake can enhance lung function. In the meantime, maintaining a healthy, balanced diet, avoiding smoking, engaging in regular exercise, and reducing exposure to air pollution can support overall lung health.
In conclusion, the study sheds light on a potential association between vitamin K levels and lung function. Although more research is necessary to establish a causal relationship and recommendations for vitamin K intake remain unchanged, the findings highlight the need for continued exploration. Further investigations will determine if vitamin K supplementation could provide benefits for individuals with lung diseases. By promoting lung health through various lifestyle measures, individuals can strive for optimal well-being and respiratory function.
