The vitamin K is essential for the blood to clot to repair injuries. Every time you have a bleeding vitamin K stops it (being present in the blood) and enables the fast healing of minor cuts.
There are 3 forms of vitamin K:
K1 aka phylloquinone
A fat-soluble vitamin that is stable to air and moisture but decomposes in sunlight, this form is found in plant foods.
K2 aka menaquinone
Required for the blood circulation, it is formed by a friendly bacteria in the intestines.
K3 aka menadione
This form is a fat-soluble vitamin thats converted into menaquinone in the liver, it is not considered a natural vitamin K, rather a synthetic analogue .
All 3 of these end up in the liver and are used to create the blood clotting substances.
Good natural sources for vitamin K are the green leafy vegetables.Supplements are not need due to the fact a form of it is created in the intestines and unless you have intestines problems you will not suffer from deficiency.
Another function of vitamin K is to retain the calcium in the bones and redistribute it to where it is needed, this makes it important for the bone building process.
As I said is rare a person to take vitamin K supplements, but there are certain cases that call for it:
Newborn babies need supplements due to the fact that the bacteria in their intestines is not yet created. Also people that have been on a extended course of antibiotics, because they kill this bacteria so if you take antibiotics for a long period you better think for supplements.
