You're better off with green leafy vegetables.
Upshot of the preprint research is that Vitamin K may be beneficial in breaking up the blood clots in COVID-19.
Extrahepatic vitamin K status was severely reduced in Covid-19 patients, as reflected by elevated inactive MGP, and related to poor outcome. Procoagulant prothrombin activity remained preserved in the majority of Covid-19 patients, which is compatible with the increased thrombogenicity that is frequently observed in severe Covid-19. Impaired MGP activation was linked to accelerated elastic fiber degradation and premorbid vascular calcifications.
More like spinach and broccoli.
Ah, right. I was confusing Vitamin K with beta-carotine.
