The Power of Vitamin K2 for Bones

Since the day you were born, you've come into contact with Vitamin K. Traditionally, since it was discovered in 1929, vitamin K's main function in human health was thought to be blood clotting (1). This is the main function of vitamin K1. But more recently, experts have found another form of vitamin K, vitamin K2. Amazingly, there are many benefits of vitamin K2 for bones and overall health.

Unfortunately, Vitamin K2 is often deficient in adults. Here's what it does, and how you can get more.

Vitamin K2 for Bones, Teeth, and Heart Health

Benefits of Vitamin K2 for Bones

Vitamin K2 plays a key role in the metabolism of calcium, which is crucial for bone health. In fact, post-menopausal women benefit specifically K2, since it lowers the risk of osteoporosis and helps bones heal.

Vitamin K2 works together with 2 proteins; matrix GLA protein and osteocalcin. Vitamin K2 activates them, which aids in bone building and continuous bone maintenance (2, 3).

Study after study supports the benefits of vitamin K2 for bones.

Japan has conducted many long-term studies on vitamin K2. Twelve of thirteen of their studies showed significant bone improvements with high doses of Vitamin K2. In fact, K2 reduced spinal fractures by 60%, hip fractures by 77% and all other fractures by 81% (4).

Another 3-year study of almost 250 postmenopausal women revealed that vitamin K2 supplements were linked to less age-related bone mineral density (5).

Vitamin K2 for Teeth

In much of the same way Vitamin K2 is good for bones, it is also good for teeth.
Teeth require the same type of calcium metabolism and nutrients as bones. In fact, since vitamin K2 activates osteocalcin, and osteocalcin stimulates the growth of new dentin, vitamin K2 can have a great impact on teeth

Vitamin K2 for Heart Health

While calcium is great bones and teeth, when calcium remains in the arteries, hardens, and builds up, it is a huge risk factor for heart disease (678).

Vitamin K2 reduces calcium accumulation in the arteries and makes it useful for bones (9).

One study of more than 16,000 women found the highest intake of vitamin K2 resulted in a much lower risk of heart disease (10).

Another study found that a higher intake of vitamin K2 was linked to a greater-than-50% decrease in the risk of artery calcification and the risk of dying from heart disease (11).

While these studies do not provide a cause and effect relationship, they show a strong link between vitamin K2 and reduced risk of heart disease. Interestingly, the studies found that vitamin K1 had no impact on heart disease.

Natural Sources of Vitamin K2

Vitamin K2 is not abundant in the modern diet. In fact, traditional diets, full of high-fat meats, contained more vitamin K2 than current diets.

The best food sources for vitamin K2 are high-fat meats and fermented foods. The low-fat modern diet has not helped us get vitamin K2.

Animal sources include high-fat dairy, egg yolks, liver and organ meats (12).

Interestingly, our bodies can convert some vitamin K1 to vitamin K2, but not enough. For most older adults, it must be supplemented.

Our but bacteria also produces vitamin K2. Antibiotic use has likely also increased the vitamin K2 deficiency of modern times  (13, 14).

Vitamin K2 is also produced by gut bacteria in your large intestine. Some evidence suggests that broad-spectrum antibiotics contribute to K2 deficiency (15, 16).

Still, the average intake of this important nutrient is incredibly low in the modern diet.

Vitamin K2 in the Silica System

Fortunately, the Silical System provides vitamin K2 for bones along with silicon. Together, these nutrients promote bone health, bone healing, and increased protection from fractures.

Bottom Line

Vitamin K2 is incredibly beneficial for bone, teeth and heart health. Especially if you're concerned about fractures, vitamin K2 with the Silical System will promote better bone health for you.
