Vitamin K2 is an essential vitamin that many people never hear of until they have their first child and the nurse administers a Vitamin K injection. Vitamin K is a fat soluble vitamin that is important for blood clotting and that contributes to a healthy heart, bones and immune system.Vitamin K2 is found in fermented raw grass fed dairy and certain other fermented foods (like natto). This is because K2 is a product of the fermentation and is created by certain bacteria. In general, these foods contain a proportionately lower amount of K2 (compared to the K1 in greens), though much more is absorbed. Human research is still in the early stages, but we know that Vitamin K is needed for the production of MGP (matrix GLA protein), which helps avoid calcification in the arteries.
