Who Should Buy Vitamin K2
Vitamin K2 is one form of vitamin K, a relatively recently discovered vitamin that contributes to bone strength, blood clotting, and cardiovascular health. While the majority of people get enough vitamin K2 in their diet, about one-third of people eat a diet thats deficient in vitamin K2.
The best way to ensure you hit adequate K2 intake is to make sure you eat foods like kale, broccoli, soybeans, and collard greens. However, that may not be realistic for everyone: if its not, a K2 supplement is the next best thing.
People who are specifically concerned about their bone health may also want to take a vitamin K2 supplement since several clinical trials have found that vitamin K supplementation can increase bone density in the lumbar spine .
Vitamin K2 could also be useful for improving cardiovascular health, as many of the proteins that rely on vitamin K are associated with reducing the buildup of plaque inside your arteries. Beyond bone health and heart health, there are a few special groups who are particularly prone to a vitamin K2 deficiency.
These groups include people with celiac disease and people who have had gastric bypass surgery or other weight-loss surgeries. These conditions affect your ability to absorb vitamin K, which puts you at risk for deficiency in the long run.
Interaction Of Vitamin K2 And Vitamin D3
Vitamin K2 should always be taken in conjunction with vitamin D3, as the two substances work together and promote bone formation. There are scientifically substantiated indications that calcium, without a sufficiently high level of vitamin K2, can only to a limited extent help to preserve healthy bones.Vitamin K2 should always be taken in conjunction with vitamin D3, as the two substances work together and promote bone formation.

Similar to Vitamin K1, Vitamin K2, MK-4 has been shown to be beneficial in the blood coagulation process. Vitamin K2, MK-4 is a synthetic form of Vitamin K2. It differs from MK-7 which is the natural form of Vitamin K2.

Although many people in Eastern cultures consume fermented soybeans, the slimy and smelly taste and texture of them often make it too harsh and unpleasant to consume. As a result, getting an adequate amount of MK-7 is easier and more convenient with supplementation of Innerzymes Vitamin K2, MK-7.

What Is Vitamin K
Vitamins are nutrients that help to support proper body functions, and every different vitamin plays a special role in the body.
Vitamin K, a vitamin found in certain foods and synthesized by gut bacteria, plays a special role in the process of blood clotting and bone formation.
Discovered in 1929, major breakthroughs in vitamin K research are still happening.
For example, important amino acids and vitamin K-dependent proteins that linked the vitamin to bone health were not discovered until the 1970s, and more dependent proteins continue to be discovered with the latest discovery occurring in 2008 according to the published history of Vitamin K research.
Vitamin K is a group of compounds, with the most common known as vitamin K1 and K2 according to Oregon State University. Vitamin K1 is found in some vegetables and leafy greens, while vitamin K2 is mostly found in meats, eggs, cheeses and is synthesized by intestinal bacteria. Some of the best vitamin K foods include asparagus, broccoli, spinach, beans, soybeans, eggs, strawberries, and meat.
