Vitamin K plays an important role in blood clotting and prevents that we bleed to death. Read more here about what other effects it has on our bodies.

What are vitamins?

Vitamins are organic compounds which the body in only small amounts or not at all capable of forming itself. Therefore, vitamins are absorbed from the diet to maintain physiological functions upright.

They are divided into two major groups:

o Fat-soluble vitamins (A, D, E, K)
o Water-soluble vitamins (B group, C)


Vitamin K

With vitamin K, a distinction is the vitamin K1 (phylloquinone), which is included in green plants, and vitamin K2 (menaquinone), which is produced by intestinal bacteria in the body and found in animal foods. The letter “K” is the abbreviation for the Latin word “coagulation” (clotting).
Vitamin K is absorbed from the diet, then it is absorbed in the small intestine and transported to the liver. This is about half the dietary vitamin K1 and the menaquinones produced by intestinal bacteria themselves saved.

Effect on the body

The procoagulant effect of the vitamin is important for the Blutungsstoppung injuries, so there is no hemorrhage. In this physiological process activates the clotting vitamin K substance “prothrombin” in liver cells. Previously it was thought that vitamin K is important for blood clotting factor. Today we do know that the vitamin also contains a previously unknown amino acid in the liver cells from the protein substance produced glutamic acid.

Vitamin C also supports bone formation by activating a specific enzyme and thus prevents osteoporosis because it promotes the recovery and the incorporation of calcium. Furthermore, it prevents against cancer, heart protects against plaque buildup in the arteries, lowering LDL-cholesterol, wounds can heal quickly and is important for healthy teeth and liver function.

What amount does the body need?

The vitamin K needs are met in a healthy person by the self-production of intestinal bacteria, the food will be about 20% absorbed. The amount specified in women is 60-65 mg / day in males at 70-80 mg / day. Increased with increasing age, the amount. A similarly increased dose is administered to newborns, because otherwise it could cause bleeding, such as a brain hemorrhage that can lead to death.


With a mixed diet of vitamin K is supplied to the body abundantly, so take vitamin KM angel only in rare cases. This is for example a liver incidence, disease of the gastrointestinal tract or after prolonged use of antibiotics possible.

The lack of symptoms make themselves as bruising, nosebleeds, bleeding gums, poor wound healing and menstrual discomfort felt and the risk of bleeding in severe injuries increased significantly. The lack of vitamin K can be corrected by tablets or drops. In addition, should stand above all vitamin K-rich foods on the menu. The highest level has given the green leafy vegetables, kale, broccoli, Brussels sprouts, parsley, chard, but also dairy products, meat and marine fish contain vitamin K.
People who are taking anticoagulants (anticoagulant) should consume the above mentioned foods in smaller amounts.
