Vitamin K
Vitamin K Functions
The main biological function of vitamin K is to aid in the calcium-binding function of proteins that are needed for blood clotting. This is a very important aspect as clotting is the body’s natural way to prevent a person from losing to much blood in the event of an injury. When you receive a cut or other type of open wound, the blood should clot on its own preventing a person from bleeding to death with minor or moderate wounds.
Uncontrolled blood clotting is also dangerous for a person as this can form clots which block the flow of blood to arteries resulting in heart failure, stroke and so forth. Vitamin K helps to regulate the proteins that prevent this from happening as well. Vitamin K may also play an important role when it comes to cell growth and the aging process of the nervous system. However, more studies are needed to determine its exact action concerning these functions.
Known Vitamin K Deficiencies and Food Sources
There are a few obvious signs that would indicate that a person is suffering from a Vitamin K deficiency, they include the following:
- Uncontrollable bleeding
- Bruising easily
- Excessive nosebleeds
- Bleeding gums
- Blood in the urine or stool
- Tarry black stools
- Extremely heavy bleeding during menstrual cycle
It is very unusual for a healthy adult to have a vitamin K deficiency but, infants that are breast-fed are at a higher risk than newborns that are not. This is due to the fact that compared to baby formula breast milk has a very low amount of vitamin K. It is also contributed to the fact that a newborns intestine may not be colonized with bacteria that synthesize this vitamin or it may not be fully functional at birth.
