are calcium and vitamin k needed for blood clotting
The ability to bind calcium ions (Ca2+) is required for the activation of the several vitamin K-dependent clotting factors, or proteins, in the coagulation (clotting) cascade. The term, coagulation cascade, refers to a series of events, each dependent on the other, that stop bleeding through clot formation.
Osteoporosis and Vitamin K2 Interventionâthe Evidence. Since it was first discovered in 1929, vitamin K has been best been known for its crucial role in the blood-clotting process. Since that time, scientists have uncovered compelling evidence that vitamin K plays an equally important role in bone health.
