Summary of COVID-19 vitamin K studies

Studies   Meta Analysis   Hide extended summaries

7,766 patient vitamin K prophylaxis study: 14% fewer cases (p=0.04).
Analysis of 7,766 adults in France, showing higher intakes of vitamin C, folate, vitamin K, dietary fibre, and fruit and vegetables associated with lower seropositivity.

40 patient vitamin K late treatment RCT: 200% higher mortality (p=1), 200% higher ICU admission (p=0.6), and 17% shorter hospitalization (p=0.52).
RCT 40 hospitalized COVID-19 patients showing vitamin K2 supplementation was well-tolerated and reduced dp-ucMGP levels, reflecting improved vitamin K status, but did not affect desmosine, a marker of elastic fiber degradation. The study was not powered to assess effects on clinical outcomes. Authors suggest that the dose may have been insufficient to fully correct the vitamin K deficiency seen in COVID-19, and that higher doses might be required to achieve potential protective effects against inflammation or lung damage.
