People who experience inadequate intake of vitamin K, an essential element present in green vegetables, could face an elevated susceptibility to compromised lung well-being, as per recent research. The findings of the study indicate that people with insufficient levels of vitamin K in their blood may have an increased vulnerability to ailments like wheezing, asthma, and chronic obstructive pulmonary disease (COPD).

Vitamin k promotes blood clotting and wound healing

Vitamin K plays a vital role in promoting blood clotting and supporting wound healing. It is abundant in leafy greens, cereal grains and vegetable oils. Despite this, the impact of vitamin K on lung well-being has remained uncertain until recent times.

The most recent discoveries, as documented in ERJ Open Research, do not alter the current recommendations regarding vitamin K intake. However, they provide further support for the need to conduct supplementary studies on the potential advantages of vitamin K supplements for specific individuals.

Danish researchers from Copenhagen University Hospital and the University of Copenhagen conducted a study involving 4,000 participants aged 24 to 77. The participants underwent lung function tests, provided blood samples, and answered health-related questions. The study used a blood test marker called dp-ucMGP to detect low vitamin K levels. Lung function was assessed through spirometry, measuring factors like forced expiratory volume (FEV1) and forced vital capacity (FVC).

Low levels of vitamin K linked to decreased FVC and FEV1 values

The study found a link between low vitamin K levels and decreased FVC and FEV1 values. Individuals with insufficient vitamin K were also more prone to various health conditions.

Dr. Torkil Jespersen said that the benefits of vitamin K in heart, blood, and bone health is established, yet its impact on lung health remains largely unexplored. Jespersen added that this study, the first of its kind on a large scale, indicates a potential link between vitamin K and lung well-being, highlighting its role in maintaining healthy lungs.

The current research findings do not change the existing vitamin K intake recommendations. However, they indicate a need for further investigation into the potential benefits of vitamin K supplementation, particularly for individuals with lung disease.
