Vitamin K2, K1 & K Supplements

Vitamin K refers to a group of fat-soluble vitamins that play a role in blood clotting, bone metabolism, and regulating blood calcium levels.

The body needs Vitamin K to produce prothrombin, a protein and clotting factor that is important in blood clotting and bone metabolism. Deficiency is rare, but, in severe cases, it can increase clotting time, leading to haemorrhage and excessive bleeding.

Vitamin K1 (phylloquinone) is obtained from leafy greens and some other vegetables and Vitamin K2 (menaquinone) is largely obtained from meats, cheeses, and eggs, fermented foods and synthesized by bacteria.

Benefits of taking a Vitamin K supplement:

Bone health

There appears to be a correlation between low intake of Vitamin K and osteoporosis. Several studies have suggested that Vitamin K supports the maintenance of strong bones, improves bone density and decreases the risk of fractures.

Memory

Increased blood levels of Vitamin K have been linked with improved memory in older adults. In one study, healthy individuals over the age of 70 years with the highest blood levels of Vitamin K1 had the highest verbal episodic memory performance.

Cardiovascular health

Vitamin K may help keep blood pressure lower by preventing the build-up of minerals in the arteries. This enables the heart to pump blood freely through the body. Adequate intake of Vitamin K has also been shown to lower the risk of stroke.

People who use blood-thinning medications, such as warfarin, or Coumadin, should not start consuming additional Vitamin K without first asking a doctor.
