Which vitamin helps in blood clotting?

ANSWER: Which vitamin helps in blood clotting?


  • Vitamin K is the vitamin that primarily aids in blood clotting.
  • Vitamin K exists in two main forms: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).
  • It plays an important role in the production of certain proteins that are involved in the coagulation process.
  • These proteins help to form blood clots, which are essential for stopping bleeding and promoting wound healing.
