The benefits of Vitamin K are becoming increasingly obvious by the accumulating evidence supporting an active role for this essential vitamin in bone health.
High intakes of Vitamin K are associated with a lower risk of hip fracture in women; and conversely, low intakes of K are associated with low bone mineral density and increased risk of bone fractures.
Other Benefits of Vitamin K
This vitamin has a key role in the synthesis of at least two proteins involved in calcium and bone metabolism.
One of these proteins has been shown to be a strong inhibitor of vascular calcification.
Thus K appears to have a role in maintaining vascular health.
In addition, vitamin K may influence bone metabolism through its effect on urinary calcium excretion.
Vitamin K is made by bacteria, including beneficial flora found in the human GI tract.
However, a newborn’s gastrointestinal tract is typically sterile for a few days after birth.
The production of this vitamin and, therefore, clotting factors, begins by the fourth day of life, giving babies their ability to clot blood.
To help to protect them, newborns are typically given vitamin K injections shortly after birth.
People who are at risk of having problems related to abnormal blood clotting, such as those with a history of stroke or heart disease, are often put on anti-coagulation therapy.
These medications reduce blood clotting by competing with vitamin K.
Anyone on anticoagulant medicine (blood thinners) should know that the amount of K in the diet may affect how well the medications work.
