Study Links Vitamin K Deficiency to Severe COVID-19 Cases

This study was conducted in collaboration with the Maastricht Cardiovascular Research Institute (Netherlands) between March 12 and April 11 by British scientists who established a link between vitamin K deficiency and the development of severe forms of coronavirus. It was revealed during a comparative study on a group of patients with severe forms of Covid-19 compared to another group of uninfected people.

According to the study, this critical form of Covid-19 causes blood clotting and degradation of the elastic fibers in the lungs. Thanks to vitamin K, a key element in the production of proteins, coagulation is regulated and the lung fibers often attacked by the coronavirus are thus protected.

For Dr. Rob Jansen, people who died from Covid-19 and were in intensive care had lower levels of vitamin K compared to healthy people. "We believe there is a relationship between vitamin K and how the disease progresses."

This vitamin includes several molecules, particularly K1 and K2. It is found in eggs, blue cheeses and green vegetables, such as spinach, for example. In addition, another study is now awaiting launch to see if the intake of vitamin K can help limit the consequences of the disease.
