16 Jun 2021 --- A new Kappa Bioscience-backed study has found low vitamin K status to be predictive of higher mortality for COVID-19. The latest findings suggest that vitamin K could play a role in the disease mechanisms, with vitamin K2 proposed as a potential supplement to help improve outcomes of the disease. The study also confirmed the results of a previous study that vitamin K status is lower in hospitalized patients with COVID-19 compared to healthy controls.
