Patients who have died or been admitted to intensive care with Covid-19 have been found to be deficient in a vitamin found in spinach, eggs, and hard and blue cheeses, raising hopes that dietary change might be one part of the answer to combating the disease.
Researchers studying patients who were admitted to the Canisius Wilhelmina hospital in the Dutch city of Nijmegen have extolled the benefits of vitamin K after discovering a link between deficiency and the worst coronavirus outcomes.
Covid-19 causes blood clotting and leads to the degradation of elastic fibres in the lungs. Vitamin K, which is ingested through food and absorbed in the gastrointestinal tract, is key to the production of proteins that regulate clotting and can protect against lung disease.
The Dutch researchers are now seeking funding for a clinical trial, but Dr Rob Janssen, a scientist working on the project, said that in light of the initial findings he would encourage a healthy intake of vitamin K, except to those on blood-thinning medications such as warfarin.
He said: “We are in a terrible, horrible situation in the world. We do have an intervention which does not have any side effects, even less than a placebo. There is one major exception: people on anti-clotting medication. It is completely safe in other people.
