Vitamin K is essential for the formation of prothrombin, a protein involved in the clotting process, so that its deficiency increases the risk of bleeding. Some studies also indicate that it helps maintain healthy bones in adulthood.
There are two types of vitamin K:
* Vitamin K1 or phylloquinone, is found naturally in foods
* Vitamin K2 or menaquinone, is produced by bacteria in the colon.
We find this in the following foods:
* Spinach and other green leafy vegetables.
* Coles (cabbage, broccoli, cauliflower, Brussels sprouts.)
* Legumes (chickpeas, lentils, soybeans and soy products)
* Liver
* Egg yolk.
Although to a lesser extent is also present in meats, grains fruits and vegetables.
Its deficit is usually rare, but usually occurs when it is not absorbed, due to prolonged treatment with antibiotics, or surgery involving portions of the intestine where it is absorbed. People who suffer from bleeding beyond are prone to bruising.
Who are medicated with a blood thinner (heparin or warfarin) should not eat food sources of vitamin K, since they reduce the effectiveness of the drug. Please consult with your doctor.
