Vitamin K is one of the essential vitamins for a human body. According to Healthline, Vitamin K is responsible for making you from bleeding when you got injured or cut. However, this vitamin can also make another body systems work like a clock. However, the necessity of taking Vitamin K supplement or foods rich in this vitamin expands beyond blood clotting.

The common types of Vitamin K

What is Vitamin K? It belongs to the group of fat-soluble vitamins and sometimes called as Vit K or K-vitamin. It was discovered in 1935 by the Danish biochemist Henrik Dam, who received the Nobel Prize for this discovery. Since those times, a few substances that can be classified as vitamin K were discovered. In the green parts of plants and vegetables, the natural type called K1 is formed. The bacteria living in the human intestines synthesize Vitamin K2. Both natural K-vitamin types are used for ceasing bleeding and certain diseases of the digestive and pulmonary system. Most patients going through the treatment of hepatitis or other liver diseases need to take Vitamin K capsules daily. Natural forms of Vitamin K are resistant to heat and do not break down when you are cooking foods rich in this vitamin.

Additionally, there are synthetic analogs of K-vitamin. The water-soluble K3 vitamin (also known as Vicasol) can be rarely found in nature. There are also purely synthetic K4, K5, K6 and K7 forms that are derived only chemically in laboratories for medical needs. All synthetic forms of K3 vitamin are mostly used in medicine for manufacturing pills (coagulants).
