This means that we have to get in from foods " for it be created in the gut" , and many people don't eat enough vegetables to obtain vitamin K.

We may also be unwittingly reducing our supply. For example, hydrogenated oils in margarine and baked goods may stop the proper utilization of vitamin K in the body.

Cholesterol lowering drugs , some laxatives and drugs that interfere with how  fat is absorbed also reduce vitamin K. Even low fat diets and very high protein diets (that don't include greens) can reduce our vitamin K.

Of the two forms of Vitamin K, we particularly need K2. Natural vitamin K2, is the effective form of vitamin K because it activates matrix gla, a special protein that is necessary for the vascular tissues to make use of and then remove excess calcium.

According to Dr. Michael Colgan in his book Strong Bones, health authorities and many physicians  do not know that strong bone is impossible without sufficient vitamin K and require re-education. They were taught that vitamin K is primarily required for blood clotting, and as a result, it has been wrongly blamed for too much blood clotting in our bodies. But excess vitamin K is not responsible. Dr. Colgan states that scientists have known for 50 years that blood clotting is not controlled by the amount of vitamin K we ingest and that blood coagulation is only one of its functions. "The major role of vitamin K is to make bone matrix proteins and their conversion into a form which binds calcium into crystal to create bone structure."

Individuals on blood thinners such as Warfarin should not take vitamin K2 supplements. Always consult first with your doctor or natural health practitioner before starting a supplement program. Natural food sources are typically the safest way to provide the body with the needed vitamins and nutrients.
