Some Important Facts About “Vitamin K” That You Need to Know

Have you ever read about vitamin K? It is a vitamin that is essential for the bones and blood. As produced by intestinal bacteria, it rarely lacks our body. Yet it is found in foods such as spinach and other green leafy vegetables. Symptom of its deficiency is the calcification of the cartilage and poor wound healing.

There are three common types of this vitamin, namely vitamin K1 (phylloquinone) – is obtained from plants, vitamin K2 (menaquinone) – produced by intestinal bacteria, and vitamin K3 (menadione, fitomenadion), which is produced synthetically and is not found in nature. The presence of vitamin K1 and K2 is found in the tissues of animals and humans.

Vitamin K activates proteins involved in blood clotting and prevents calcification of the arteries and tissues, strengthens the bones and is responsible for cellular processes.

Eat spinach in combination with oil

K-vitamin is fat soluble (lipophilic), which means that it is very much bound to the fat. A good source of vitamin K is cooked spinach. If we eat it along with oil, the body will absorb 20 percent of the K-vitamin. However, vitamin K is not absorbed from raw spinach.
