Life Extension Low-Dose Vitamin K2 is able to consistently provide vitamin K to the body to aid in bone and heart support. This is possible by using the form of vitamin K2 called menaquinone-7 (MK-7), which takes longer for the liver to metabolize. Because it takes longer to metabolize, the K2 remains accessible to the body for a full 24 hours and leads to greater levels for the body to absorb when compared to vitamin K1.2

Vitamin K is essential in the body for blood to be able to clot. Without vitamin K even a small cut would never stop bleeding and lead to major health concerns.1 While vitamin K deficiency is uncommon it does occur in people who cannot properly absorb it from their foods. Bruising and bleeding is more common in people with low vitamin K levels.

While blood clotting is vitamin K’s main function, it supports health in other parts of the body as well. It facilitates the transport of calcium from the bloodstream to the bones, maintaining bone health and strength all while decreasing the risk of calcium buildup in the arteries. Without vitamin K to help calcium in the blood reach the bones it becomes stuck in the bloodstream and bind to the walls of the arteries.3 Over time this buildup hardens the arteries and leaves less room for the blood to flow, leading to health risks.

A large-scale study known as the Rotterdam Heart Study, showed that people who consumed the highest amounts of K2 experienced a healthier cardiovascular system compared to those who consumed the least4 Greater consumption of K2 was also linked to reduced calcium buildup in the aorta, and those who consumed less K2 showed more buildup, and even severe calcification.5,6

In those at risk of osteoporosis, heart, and circulatory problems even a slight decrease in vitamin K levels can have a serious effect on their health.7 So supplementation of vitamin K is important for helping the body get enough of this vitamin when food isn’t enough. And Low-Dose Vitamin K2 provides the most vitamin K the body can use throughout each day.
