Vitamin K2 is a member of the fat-soluble vitamin K group – a family of vitamins essential for blood coagulation (clotting) and maintaining bone density. Vitamin K1, or phylloquinone, the most dominant of the vitamin K compounds, is readily available from leafy green vegetables; vitamin K2, also known as menaquinone, is found naturally in animal-based foods, such as meat, poultry, cheese, eggs and butter. Vitamin K2’s ability to protect blood vessels from calcification could prove useful in protecting against heart disease. Vitamin K might decrease the effectiveness of blood-thinning medication, such as Warfarin (Coumadin). Nutrition Expert sources the latest information and advice from a range of qualified doctors, nutritionists and coaches. While the importance of vitamin D has become more fully appreciated, another vitamin that is just as important as vitamin D, vitamin K2, needs wider recognition.
Vitamin K1 is the primary form of vitamin K responsible for blood clotting, whereas vitamin K2 is essential for bone strength, the health of arteries and blood vessels, and plays a role in other biological processes as well, including tissue renewal and cell growth. The difference between vitamins K1 and K2 was first established in the Rotterdam Study,2 published in 2004. Examples of foods high in vitamin K2 include raw dairy products such as certain cheeses, raw butter, and kefir, as well as natto (a fermented soy product) and fermented vegetables like sauerkraut.
However, not every strain of bacteria makes K2, so not all fermented foods will contain it. Most commercial yogurts are virtually devoid of vitamin K2, and while certain types of cheeses, such as Gouda, Brie, and Edam are high in K2, others are not.
One of the best sources I've found is to ferment your own vegetables using a special starter culture designed with bacterial strains that produce vitamin K2.
My research team found we could get 400 to 500 micrograms (mcg) of vitamin K2 in a two-ounce serving of fermented vegetables using such a starter culture, which is a clinically therapeutic dose. MK-4 (menaquinone-4), a short-chain form of vitamin K2 found in butter, egg yolks, and animal-based foods. This is the one you'll want to look for in supplements, as this form is extracted from real food, specifically natto, a fermented soy product. Research3 has shown MK-7 helps prevent inflammation by inhibiting pro-inflammatory markers produced by white blood cells called monocytes.
Vitamin K2 is an important adjunct to vitamin D, without which vitamin D cannot work properly. This means that if you take high doses of oral vitamin D you need to remember to also increase your vitamin K2 intake from either food or a MK-7 supplement. If you get your vitamin D primarily from sun exposure then this issue is largely circumvented, as your body is then able to regulate its vitamin D production. Vitamins D and K2 also work synergistically with magnesium and calcium, so this quartet should ideally be taken in combination. At least 50 percent of the general population is at risk of vitamin D deficiency and insufficiency, and as many as 97 percent may be lacking in vitamin K2.4 This could very well be due to the fact that we stopped eating fermented foods with the advent of refrigeration and other food processing techniques.
In the 1980s, it was discovered that vitamin K is needed to activate the protein osteocalcin, which is found in your bone.
Without vitamin K, these and other vitamin K-dependent proteins remain inactivated, and cannot perform their biological functions. Vitamin K2 also helps prevent arterial calcification by shuttling calcium away from areas where it shouldn't be (in the lining of your blood vessels) to where it's really needed (such as in your bone).
People who consumed 45 mcg of K2 daily lived seven years longer than people getting 12 mcg per day. More recently, a study12 published in the journal Thrombosis and Haemostasis found that MK-7 supplementation improved arterial stiffness in otherwise healthy postmenopausal women.


As mentioned, vitamin K2 also plays a crucial role in bone health,13 and may be critical for the prevention of osteoporosis. A recent Chinese meta-analysis16 of 19 randomized controlled trials found that vitamin K2 supplementation significantly improved vertebral bone density in postmenopausal women, and reduced the risk of bone fractures.
Another three-year long placebo-controlled study17 done in the Netherlands found that postmenopausal women taking 180 mcg of MK-7 per day increased their bone strength and saw a decrease in the rate of age-related bone mineral decline and reduced loss of bone density, compared to those taking a placebo. Vitamin K2 also plays an important role throughout pregnancy and during breastfeeding for the healthy growth of the child. Since there are no reported cases of overdose of vitamin K2, and appears to have no toxicity issues, it may be prudent to double or even triple your intake while pregnant. Clearly, you want both vitamin K1 and K2, but you're virtually guaranteed to not get enough K2 from your diet unless you eat the proper fermented foods.
As for a clinically useful dosage of vitamin K2, some studies — including the Rotterdam study25 — have shown as little as 45 micrograms (mcg) per day is sufficient. A 2006 research review published in Current Drug Safety(i) concluded that combining vitamin K2 with a class of drug which prevents bone mass loss (known as bisphosphonate) could help prevent fractures in postmenopausal women who are deficient in vitamin K and suffer from osteoporosis. A study published in the Journal of Nutrition(ii) which examined the vitamin K dietary intake of 4,807 people suggested an adequate intake of vitamin K2 could be important for coronary heart disease prevention. Patients receiving dialysis treatment for kidney disease and people with blood clotting problems should seek medical advice before taking vitamin K2.
If you have a health problem consult your GP and check compatibility of new supplements with your GP or Pharmacist if you are taking any prescription medication.
We always endeavour to have the most up to date information possible and publish new content weekly. Michael Holick and co-authors review the history of vitamin K and its many benefits, including its significance for skeletal and cardiovascular health. A variety of foods were measured for vitamin K content, and vitamin K1 was found to be present in high amounts in green leafy vegetables, such as spinach, kale, broccoli, and cabbage. For example, pasteurized dairy and products from confined animal feeding operations (CAFOs) are NOT high in K2 and should be avoided. MK-4 also has a very short biological half-life — about one hour— making it a poor candidate as a dietary supplement. You could actually get loads of MK-7 from consuming natto, which is relatively inexpensive and available in most Asian food markets.
It stays in your body longer, and has a longer half-life, which means you can just take it once a day in very convenient dosing. K2's biological action is also impaired by a lack of vitamin D, so you really need to consider these two nutrients together. Failing to do so could cause harm, as without K2, your body will not be able to complete the transport of calcium into the proper areas, and arterial calcification could set in.
Unfortunately, most people are deficient in both vitamins D and K, and magnesium insufficiency is also common.
Research8 published in the Journal of the American College of Cardiology suggests statin drugs may increase calcification in the arteries, and other research9 shows that statins deplete vitamin K2. A decade or so later, another vitamin K-dependent protein was discovered: matrix Gla protein (MGP), found in your vascular system.
In the Rotterdam Study,10 which ran for 10 years, those who consumed the greatest amounts of K2 had the lowest risk of cardiovascular disease, cardiovascular calcification, and the lowest chance of dying from cardiovascular disease. This study has been lauded as significant because while previous studies have only been able to show an association, this is the first to confirm that long-term use of vitamin K2 in the form of MK-7 does result in improved cardiovascular health. Osteocalcin is a protein produced by your osteoblasts (cells responsible for bone formation), and is utilized within the bone as an integral part of the bone-forming process.


Not only does it affect the development of both primary and adult teeth; it also helps develop proper facial form and strong bones. Mayo Clinic researchers discovered that people with the highest intake of vitamin K2 had a 45 percent lower risk for this type of cancer, compared to those with the lowest vitamin K2 intake.21 They attribute this effect to vitamin K2's ability to inhibit inflammatory cytokines, which are related to this type of lymphoma, and its role the life cycle of your cells. Holick's paper,24 vitamin K2 has anti-inflammatory, anti-oxidative, and anticarcinogenic properties, and in addition to cancer and diabetes, MK-7 in particular may also offer benefits for age-related macular degeneration.
When this process occurs in the blood vessels, plaque can build up in the arteries, resulting in coronary artery disease. However with the constant research in this field sometimes some of our older articles can become out of date.
Interestingly, while the K1 in vegetables is poorly absorbed, virtually all of the K2 in fermented foods is readily available to your body.
When MGP remains inactivated, you end up with serious arterial calcifications, and this is why vitamin K is so crucial for cardiovascular health.
In a subsequent trial called the Prospect Study,11 16,000 people were followed for 10 years.
Holick's 2014 vitamin K2 paper,18 illustrates the effect of vitamin K on bone and vascular health.
Fortunately, you don't need to worry about overdosing on K2, as it appears to be completely non-toxic. Individual articles are based upon the opinions of the respective author, who retains copyright as marked. Evidence suggests vitamin K can even reverse arterial calcification induced by vitamin K deficiency.
Here, they found that each additional 10 mcg of K2 in the diet resulted in nine percent fewer cardiac events. Vitamin K functions as a cofactor for the enzyme that catalyzes the carboxylation of osteocalcin. You can obtain healthy amounts (about 200 mcg) of K2 by eating 15 grams (half an ounce) of natto each day, or fermented vegetables. Compliance can therefore be a problem, as people are more likely to take something that has a noticeable effect.

If you fermented them using a starter culture designed with vitamin K2-producing bacteria, one ounce will give you about 200 to 250 mcgs. This may not happen with vitamin K2, but that certainly does not mean it's not doing anything.
