Just like vitamins A, D, and E, vitamin K is a fat soluble vitamin, meaning that it is absorbed along with fats in the diet and is stored in the body's fatty tissues for future use. Vitamin K2 is primarily responsible for directing the proper utilization of calcium in the body, guiding it to support bone health and preventing unwanted calcification in arteries and soft tissues (1). An astounding 99% of the body's calcium is concentrated within the bones and teeth, leaving a mere 1% for various physiological functions elsewhere.  Vitamin D promotes calcium absorption and then to join forces with Vitamin K2, who guides calcium to the bones, and teeth.

When talking about bone health Vitamin K2 centers around the activation of key proteins called osteocalcin, which are produced by osteoblasts. When vitamin K2 activates osteocalcin, it transforms the protein, enabling it to bind effectively with calcium ions. This binding is pivotal, as it transforms calcium into an indispensable building block within the bone matrix (1).

Its also responsible for preventing calcium accumulation in the wrong places, like arteries and soft tissues. When the build up of fat and cholesterol forms in our arteries we develop something called coronary artery calcification which blocks the flow of blood to the heart. As these calcified plaques obstruct the arteries, the heart may receive insufficient oxygen and nutrients. Researchers found in a recent study, that for every 10 mcg Vitamin K2 (MK-7) consumed the risk of coronary heart disease was reduced by 9 percent.
