Study Links Low Vitamin K Levels to Poor Lung Function and Respiratory Issues

A recent study published on August 9 in the journal ERJ Open Research reveals a potential association between low levels of vitamin K in the blood and compromised lung health. Researchers from Copenhagen University Hospital and the University of Copenhagen conducted the study, which involved 4,092 participants aged between 24 and 77 residing in Copenhagen.

Vitamin K, primarily found in leafy greens, vegetable oils, and cereal grains, is renowned for its role in blood clotting and wound healing. However, its impact on lung health remains relatively unexplored. The study incorporated lung function tests, blood samples, and health/lifestyle questionnaires. A marker for low vitamin K levels, dp-ucMGP, was assessed from blood samples. Lung function was measured through spirometry, gauging forced expiratory volume (FEV1) and forced vital capacity (FVC).

The outcomes unveiled a correlation between lower vitamin K levels and reduced FEV1 and FVC averages. Participants with diminished vitamin K levels were also more inclined to report conditions like chronic obstructive pulmonary disease (COPD), asthma, and wheezing.

Dr. Torkil Jespersen, a researcher on the project, underscored the pioneering nature of their study: "To our knowledge, this is the first study on vitamin K and lung function in a large general population. Our results suggest that vitamin K could play a part in keeping our lungs healthy."

Nonetheless, Dr. Jespersen emphasizes that the findings do not warrant immediate changes to vitamin K intake recommendations. Instead, the study encourages further investigation into potential benefits of vitamin K supplementation, particularly for individuals dealing with lung ailments.

As part of their ongoing exploration, the research team is embarking on a significant clinical trial, the Inter VitaminK trial. This trial will evaluate vitamin K supplementation versus a placebo in terms of impacts on heart, bone health, and, prompted by the recent findings, lung function.

Expert Insights on Unveiling Vitamin K's Influence on Lung Function

The recent revelations surrounding the connection between vitamin K levels and lung function have sparked intrigue within the medical community. As researchers from Copenhagen University Hospital and the University of Copenhagen shed light on this previously unexplored facet of vitamin K's impact, experts in the field offer their valuable insights.

Dr. Apostolos Bossios, Secretary of the European Respiratory Society’s assembly on Airway diseases, asthma, COPD, and chronic cough, provides an insightful perspective on the significance of the findings. He emphasizes that the study suggests a noteworthy link between individuals with low vitamin K levels in their blood and compromised lung function. While the results are preliminary, they point towards a potential avenue of investigation that could enhance our understanding of lung health.

Dr. Bossios underscores that the correlation between vitamin K and lung function merits further exploration. He highlights that more research is needed to determine whether boosting vitamin K levels could indeed lead to improved lung function or ameliorated respiratory conditions. This underscores the importance of conducting comprehensive clinical trials that delve into the practical implications of these initial findings.

As the medical community seeks to unravel the intricacies of how vitamin K impacts various aspects of human health, including lung function, these discoveries serve as a catalyst for deeper inquiry. Dr. Bossios' commentary aligns with the consensus that this study represents a promising stepping stone toward a better comprehension of the connections between nutrition and lung health.

In essence, the expert commentary underscores the significance of these findings, urging further investigation into the potential benefits of vitamin K supplementation for enhancing lung function and addressing respiratory conditions. The medical community eagerly anticipates the results of ongoing studies and clinical trials that will shed light on the practical implications of these intriguing discoveries.
