What Does Vitamin K Do For Your Body?

Vitamin KVitamin K is a group of fat soluble vitamins split into two main subdivisions.

Vitamin K1

This is probably best known for its important role in blood coagulation. A deficiency of vitamin K1 means that any open wound would take longer to for the blood to clot and start the healing process. Sufferers from heart problems who have been put on blood thinning medication such as warfarin to stop or slow down the formation of blood clots leading to strokes or clots on the lungs should avoid foods rich in Vitamin K1.

The principal sources for K1 are green leafy vegetables such as:-

Spinach Parsley
Kale Asparagus
Brussel Sprouts Green Beans
Cabbage Collards
Romaine Lettuce Cauliflower
Swiss Chard Avocados
Grapes Kiwi Fruit

Vitamin K2

Vitamin K2 is produced by bacteria in the gut which can also convert K1 to K2. Vitamin K2 helps to prevent bone loss and fractures in osteoporosis, cirrhosis of the liver, inactivity caused by a stroke, Alzheimer’s and Parkinson disease    and blood thinning medication. It may also have a role to play in the treatment of prostate and liver cancer.

Since 1995 it has been approved in Japan for treatment and prevention of osteoporosis although the United States Federal Drug Agency has not followed suit.

Vitamin K Deficiency Rare In Healthy Adults

Vitamin K is stored in the body fat while any deficiency is rare in healthy adults it can be triggered by the onset of old age. Also diseases such as liver damage and alcoholism, and those on severe diets, bulimics and takers of anti blood clotting drugs can affect the body’s absorption of vitamin K. Among the symptoms are heavy menstrual bleeding, heavy bruising, nose bleeds, bleeding gums, anaemia. Vitamin K2 production in the gut is depleted when using broad spectrum antibiotics.

Enough Vitamin K Obtained From Normal Diet

Adults in good health should obtain all the Vitamin K their body needs from following a normal diet.
In the US and other countries it is considered good practise to administer Vitamin K to babies shortly after birth as their blood clotting abilities are reduced to between 30-60% of normal for the first few days of their life.

How Much Vitamin K Should You Take?

The recommended intake of vitamin K for healthy adult males is 120 micrograms a day and 90 micrograms for adult women. The elderly may benefit from taking vitamin K supplements but should only do so on medical advice. It is also beneficial in the form of a cream to treat broken spider veins, diminish post operative bruising, under eye dark shadows and rosacea.

Elderly Prone To Vitamin K Deficiency

Those approaching late middle age who keep to a regular active exercise regime and consider themselves healthy should be aware of the dangers of the onset of osteoporosis. The increasing fragility and proneness to fracture of the bones is not usually accompanied by any warning symptoms. Any lack of Vitamin K will increase the chances that fractures may occur even as a result of even a minor fall.
