Vitamin K

Also known as Natural Vitamin K2. The role of vitamin K has for the past decade been linked to two of the most important health issues, osteoporosis and cardiovascular disease. This link specifically centers on calcium utilization, whereby inadequate metabolism of calcium can result in concurrent arterial calcification and osteoporosis.

Natural Vitamin K2:
  • Promotes the synthesis of proteins involved with calcium utilization
  • Vitamin K2 is much more effective in helping inhibit bone loss
  • Vitamin K2 consumption may help inhibit arterial calcification


  • Research conducted in laboratories, in vivo studies and human clinical research have demonstrated vitamin K2's superior benefits to vitamin K in helping prevent bone loss, and have clearly shown that only vitamin K2 plays a role in cardiovascular health.

    Vitamin K is used in the body to control blood clotting and is essential for synthesizing the liver protein that controls the clotting. It is involved in creating the important prothrombin, which is the precursor to thrombin - a very important factor in blood clotting. It is also involved in bone formation and repair. In the intestines it also assists in converting glucose to glycogen, this can then be stored in the liver.

    A deficiency of this vitamin in newborn babies results in hemorrhagic disease, as well as postoperative bleeding and hematuria while muscle hematomas and inter-cranial hemorrhages have been reported.

    A shortage of this vitamin may manifest itself in nosebleeds, internal hemorrhaging.

    Toxicity does not easily occur with normal dietary intake of this vitamin, but can happen if synthetic compound vitamin K 3 is taken. High to toxic uptake in the synthetic form can cause flushing and sweating. Jaundice and anemia may also develop.

    If you are taking anti-coagulant (to prevent blood clotting) medication, consult your medical practitioner before taking a Vitamin K supplement.

    When you are prone to bruising easily, or when pregnant you might be in need of more Vitamin K. But be careful not to take too much Vitamin K in the last stages of pregnancy, since it could be toxic for the baby.
