Collection: Vitamin K

Prothrombin, a protein and clotting factor crucial to blood clotting and bone metabolism, is produced by the body with the help of vitamin K. Patients using blood thinners like warfarin or Coumadin shouldn't start taking more vitamin K without first consulting their doctor.

Plants provide phylloquinone, sometimes known as vitamin K1. It is the primary kind of dietary vitamin K from a Trusted Source. Vitamin K2, also known as menaquinone, is a less significant source and can be found in some fermented and animal-based foods.
