The Bone-Strengthening Power of Vitamin K

Vitamin K1 is well known for it’s important role in blood clotting, but there is also much scientific evidence that vitamin K plays a crucial role in both the reduction of bone fractures and in reducing abnormal calcifications in the body. This makes it an important nutrient for both bone and heart health.

Vitamin K not only helps preserve calcium in the bones, it aids the dissolution of calcium elsewhere, including in the arteries and kidneys. Studies found that those with a higher dietary intake of vitamin K2 had less heart disease and less calcification of the coronary artery. Also, it was shown that vitamin K1 supplementation slowed the progression of coronary artery calcification.

Remember, when there is an excess of calcium in the blood, there is usually a deficiency in the bones. (See Why I don’t Take Calcium).

Vitamin K1 was shown to increase bone mineral density in rats, and vitamin K2, was shown to improve the quality of bone and strengthen itagainst fracture. Calcium supplementation may increase bone density without improving its resistance to fracture, and at the same time increase calcifications throughout the body.

One study done on rats showed that vitamin K2 in the form of MK-4improved the strength of bones that had been weakened by a magnesium deficiency. (See The Role of Magnesium in Balancing Calcium).

According to Dr. Thomas Levy in his book, Death by Calcium, human studies indicate that supplementing with 45 mg daily of vitamin K2 (MK-4) will sustain bone mineral density and prevent fractures from osteoporosis. He further recommends taking a multi-K formula that includes K1, K2 (MK-4), and K2 (MK-7), as found in a product like Life Extension Super K with Advanced K2 Complex.

The good news is that there is no known toxicity or undesired side effects associated with vitamin K, even when given to newborns or pregnant women.

Even though vitamin K is a blood clotting agent, it does not cause abnormal clotting. You will still want to check with your doctor before taking vitamin K if you are taking a blood thinner like warfarin or have another medical condition.
