A large amount of human clinical data shows that vitamin K supplements play a critical part in maintaining healthy bone density by facilitating the transport of calcium from the bloodstream into the bone. Vitamin K is also required by calcium-regulating proteins in the arteries. One of these proteins is Matrix Gla-protein (MGP), which depends on a sufficient supply of vitamin K for it to be carboxylated to function properly. If there are low levels of vitamin K, MGP remains uncarboxylated and accumulates at sites of arterial calcification. As MGP is a powerful inhibitor of arterial calcification, it plays a vital role in cardiovascular health. If there is a vitamin K deficiency, blood can stick to the walls of the arteries leading to calcification. With age, even a subclinical vitamin K deficiency can present a risk to the vascular system. Vitamin K deficiency leads to higher levels of circulating undercarboxylated osteocalcin, which has been shown to be linked to increased loss of bone density in postmenopausal women (osteoporosis).

Vitamin K1 and Vitamin K2

What foods contain vitamin K2? Well, vitamin K2 (menaquinones) can be found in meat, eggs, and dairy products and is also produced naturally by bacteria in the gut, which provides a certain amount of the body´s vitamin requirements. Vitamin K2 is up to ten times more bioavailable than vitamin K1 and remains biologically active in the body much longer than vitamin K1. Vitamin K1 is cleared by the liver within eight hours, whereas measurable levels of vitamin K2 (MK-7) have been detected 72 hours after ingestion. Thus, vitamin K2 is the more favourable vitamin K supplement form providing more health benefits in the body.

Vitamin K2 for healthy arteries and blood

The Rotterdam Heart study, a clinical trial that followed 4,800 participants for seven years, showed that those who consumed the greatest quantities of vitamin K2 in their diet had a more healthy cardiovascular system than those who consumed the least. High vitamin K2 intake also corresponded to a lower build-up of calcium on the aorta, whereas those who consumed less vitamin K2 were more likely to have moderate or severe calcification. Animal studies suggest that vitamin K supplements not only block further calcification, but also reduce existing arterial calcification by 37%. Low-Dose Vitamin K2 supplement contains the menaquinone-7 form of vitamin K2, which is metabolised only slowly by the liver, thus making it available longer to provide a more consistent supply of vitamin K.
