Why do we need K vitamins?
The function of K vitamins is unique among other vitamins. K vitamins are mainly known for its blood clotting activity.
However, it is now recognized that vitamin K2 is optimal for the body to utilize calcium in order to build healthy, strong bones and to inhibit calcium deposits in the arteries.
Vitamin K activates certain proteins in the body such as osteocalcin in the bones, Matrix Gla Protein (MGP) in the arteries and clotting factors in the liver.
These proteins are dependent on vitamin K in order to bind calcium to the surface of bones, inhibit calcium deposits in the arteries and help coagulate blood.
Inadequate vitamin K – and especially lack of vitamin K2 - may result in what is known as the “Calcium Paradox” whereby too little calcium result in weak bones - while excess calcium accumulates in the arteries making them stiff and inelastic.
