Vitamin K

What is Vitamin K?

Vitamin K is a group of fat-soluble vitamins that can be found in many leafy green vegetables such as kale, spinach and broccoli. This vital vitamin can provide various powerful health benefits due to its involvement in a wide range of processes in the body.

Health Benefits:

Supports Normal Blood Clotting

It is well-established that vitamin K supports normal blood clotting and is essential for the synthesis of several blood clotting factors such as prothrombin, a protein produced by the liver. Deficiency in vitamin K can lead to reduced levels of clotting factors, causing an increased risk of bleeding and bruising, and inhibiting healthy recovery from injury.

Promotes Bone Strength

Research shows that vitamin K can be highly beneficial for bone strength and health. For example, vitamin K has been found to both increase bone mineral density and reduce fracture rates in osteoporotic people.

One argued mechanism for vitamin K's beneficial effects for bone health is the activation of osteocalcin through carboxylation, which allows osteocalcin to bind calcium and incorporate it into the bone matrix. This process is crucial to building strong bones and maintaining healthy bone density.

Supports Cardiovascular Health

Vitamin K is vital to supporting cardiovascular health and deficiency in this vital vitamin has been repeatedly linked to the development of vascular calcification and the occurrence of cardiovascular disease. By activating the Matrix Gla protein, vitamin K prevents the calcification of blood vessel walls, supporting arterial flexibility and promoting healthy blood circulation. Studies show that the inactive form of the Matrix Gla protein is associated with increased vascular calcification, insulin resistance and greater heart failure indices, leading to increased risk of cardiovascular mortality.

Typical Use:

Vitamin K can be consumed through dietary choices such as through leafy greens and some fermented foods, however many people choose to take vitamin K supplements to ensure that they are obtaining the correct levels. Many supplements containing vitamin K are specifically aimed at supporting bone and cardiovascular health.
