Functions and General Science:
The primary role of vitamin K is in the manufacture of clotting factors involved in blood clotting. It also has a key role in building health bones and incorporating calcium within the bone. Low levels of vitamin K impact on bone mineralisation, often the severity of a bone fracture is related to the level of circulating vitamin K.
Vitamin K is absorbed into the lymphatic system, mainly in the upper part of the small intestine. Being a fat soluble vitamin, it is retained in the body, concentrated in the liver.
