Though largely unknown, vitamin K is essential to good health. It is needed for the normal clotting of blood and for the formation and maintenance of healthy bones. Although our bodies produce some vitamin K2, we store it in very limited amounts. A lack of this vitamin-which can be caused by a poor diet and the regular use of certain drugs such as antibiotics-is not uncommon. Fortunately, a new supplemental form of vitamin K2, menaquinone-7 (MK-7), is becoming more widely available. Vitamin K2, specifically MK-7, is showing great promise as a natural treatment for heart disease and bone loss. Available in soy products and as a nutritional supplement, MK-7 is clinically proven to be safe and effective. It may also be helpful for lowering cholesterol, preventing Alzheimer's disease, and treating some forms of cancer.
