The Connection Between Calcium and Vitamin K

Recently the news media has reported about the dangers of getting too much calcium from supplements:  increased risk of heart attack and stroke and calcium deposits in blood vessels. What you probably didn’t hear about is why.

Many of us are deficient in vitamin K. Vitamin K2 is required to activate a group of proteins that prevent minerals from depositing in soft tissue. Without these proteins, calcium isn’t directed to the bones, hardening blood vessels and making them less effective at transporting nutrients and oxygen throughout the body. The risk for heart attack increases when this occurs in the coronary arteries, the blood vessels that feed nutrients and oxygen to the heart.

Vitamin K2 is a fat soluble vitamin, which is used to make clotting proteins in the liver. Vitamin K2 is abundant in natto, a traditional Japanese fermented soybean dish, and in much smaller amounts in organic grass-fed animal products, brie, Gouda and goose liver pate. Like most exotic traditional foods, natto is an acquired taste – it has a slimy texture, a pungent taste and an even stronger smell. For the adventurous, it can be found in the refrigerated section of your local Asian supermarket.

For the less adventurous (or soy intolerant), CarePro Advance Health has three products that contain Vitamin K2 in its most potent form, K2 MK-7 (or menaquinone-7):

  • Vitamin K2 capsules 
  • Nutrient 950 with vitamin K, a multivitamin
  • K-Force, a combination product that contains Vitamin D3 and vitamin K2 

Unlike other fat soluble vitamins, Vitamin K2 has no set upper limit, and studies in rats fed large quantities of Vitamin K2 have shown no harmful effects. However, people on warfarin (also called Coumadin or Jantoven) should consult their primary care provider before starting Vitamin K2.
