Naphtoquinones or Vitamin K is the label for this group of fat-soluble compounds.  It is comprised of plant-derived Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinones) produced from animal and human intestinal bacteria.  Only Vitamin K1 and K2 are approved as a natural supplements because the synthetic form Vitamin K3 (menadione) is still under further research.

â?¢Vitamin K1 is given credit for the regulation of blood clotting.  The enzymes it releases in an intricate system tagged as the clotting cascade, functions to make blood clot as well as slow it down.

â?¢Vitamin K2 serves as a shield against osteoporosis when it releases osteocalcin and pads it into the bone to form more mass (bone mineralization),

â?¢In going through the Vitamin K cycle, it functions as an antioxidant that helps to fight free radicals to keep it from damaging the fats stored.  

Recommended dosage is 90-120 mcg for adults 19 years old and older.  Vitamin K1 and K2 (natural forms of Vitamin K) have not exhibited toxicity, such as excessive blood clotting, in cases where the individuals have taken the vitamin more than the dosage indicated above.
