Vitamin K2

What is vitamin K2? Vitamin K2, also known as menaquinone, is one of the two main types of K vitamins. Vitamin K2 is different from vitamin K1 in its molecular structure as well as some sources. Vitamin K2 is not the version most easily obtained by food sources, however there are some sources that provide vast quantities of vitamin K2. Instead, vitamin K2 is actually produced within the intestines by existing bacteria. This means that a vitamin K2 deficiency is extremely uncommon unless the intestines are not working properly or if there is a medical condition affecting the body’s ability to synthesize the vitamin.

Among the few types of food sources of vitamin K2 are egg yolk, butter, some cheeses and chicken. If there ever is a vitamin K2 deficiency, it is likely caused by a medical condition that prevents the synthesis of vitamin K2 within the intestines. If, however, vitamin K2 is lacking within the body, the effects can be severe, resulting in potential intestinal bleeding. In the past, vitamin K was given as an injection to newborn babies in many countries to prevent disease, but this is not commonly practiced anymore.

Although deficiencies of vitamin K2 are not very common, it is still a vitamin that is often taken as a supplement to achieve health benefits. Carlson Labs is one of the major companies that has completed studies on vitamin K2 and its health benefits, and Carlson vitamin K2 offerings include Carlson vitamin K2 capsules in different dosage amounts. These are purported to have cardiovascular benefits as well as bone and cartilage health. Although these products are offered, it is best to keep in mind that there is no recommended daily intake level of vitamin K2 because it is made within the body. By eating the foods that offer a source of vitamin K2 synthesis, you will likely receive the necessary amount to maintain health.

It is important to remember that vitamin K2 is a blood coagulator. This is something that is essential to achieve proper blood clotting within the body to prevent internal bleeding and other problems. However, if too much clotting is achieved, these can be potentially harmful or fatal clots if they travel to the heart or brain. Ironically, it is possible for acute vitamin K2 deficiency to have the opposite effect and lead to unwanted blood clotting. Being aware of the necessary amount of vitamin K, achieving this amount, but not getting excessive, is key to proper health.
