Vitamin K
In 1929, a Danish researcher discovered the key to stanching blood flow, aptly naming it vitamin K, for "koagulation." Now, scientists are discovering the nutrient's possible participation in bone strength, heart health, control of inflammation and prevention of diabetes.
Vitamin K is actually three different compounds, all of which are fat soluble. It is absorbed from the upper small intestine with the help of bile (or bile salts) and pancreatic secretions, and then carried to the liver.
Vitamin K also may help regulate blood calcium levels. Calcium, in addition to keeping bones strong, is also necessary for blood clotting. Accumulating evidence supports an active role for Vitamin K in bone health.
