\r\n \r\n Hard to say. K2 is the miracle substance known as "activator x" for many years by the Weston Price Foundation, until it was finally identified as K2.
\n
\nAll things work together. I imagine we go into all kinds of subtle and well as major imbalances if all our nutritional needs are not met.
\n
\nK2 needs to be in everyones diet, and hearty amounts of it for all the reasons Weston Prices says.\r\n

\r\n \r\n Thanks Arrow and Liverock. I\'m a big fan of vitamin k2 for the arteries, but it\'s so expensive that I often go through stretches of time without it. I was starting to think that if I don\'t have k2, then I should also not take my D3, and D3 is one on my list that I will not do without, from everything I\'ve learned on this forum. \r\n

\r\n \r\n kind, have you priced K2 at Swanson Vitamins and Vitacost? It may not be as good as that sold by Dr. Mercola at such high prices, but probably better than nothing.\r\n

\r\n \r\n My Swanson catalog shows only NattoK7 (form of k2), 30 softgels @ 100mcg. for $14.99, so a months worth for me and my husband would be $30.
\n
\nThe one I like that I bought in the past on Amazon was Carlson k2, 5 MG. Vitacost has that one, 180 @ $43.47, $15. a month would be a better deal. Vitacost has other choices also. I like the larger dose, not sure what others are taking. My local vitamin store has limited selection, low dose and expensive.
\n
\nI\'m overdue to make a vitamin order, prices are definitely better online, and I\'ve used Swanson and Vitacost for years. \r\n

\r\n \r\n I\'m taking Doctor\'s Best Nattokinase. I\'m specifically taking it, because it has all vitamin K removed. I can\'t remember why that is important. I trust Doctor\'s Best. I know that vitamin K1 can concentrate in the liver, which is not good. K2 will not do that. Natto is supposed to have an abundance of K2. Maybe it also contains K1, and that\'s why this brand removed all K. Another reason might be that natto is an anti-coagulator and K is a coagulator.
\n
\nThe manufacturer says:
\nVitamin K2 is known to interact with and reduce the effectiveness of Warfarin and individuals taking this drug are usually told by their doctors to avoid foods that contain a large amount of Vitamin K (e.g., Natto, Green and Yellow Vegetables and Chlorella).
\nIn order to make it possible for people taking Warfarin to benefit from consuming our NSK-SD�, we developed and patented a new technology to remove Vitamin K2 from Nattokinase product.
\n
\nI think I will get my next nattokinase with the vitamin K intact.\r\n

\nDr Davies recommends D3 and K2 together because at the levels of D3 he recommends, you will absorb more calcium than at lower levels and K2 will ensure that it is laid down in the bones and not the arteries.\r\n

\r\n \r\n Let me ask this question, if I was going to just eat food that\'s high in vitamin D3, it doesn\'t appear to be the same foods that are high in vitamin K2. I guess I\'m just seeing if I eat fish every single day, my vitamin D level would be higher than most people, but my vitamin k2 wouldn\'t change.
\n
\nSo is it also suggested that people who eat fish also have to eat eggs to balance it? I just think about the countries that eat a lot of fish and are in the sun all the time and live to be 100 years old, how are they getting k2?\r\n

\r\n \r\n This info is from https://www.whfoods.com/genpage.php?t...rient&dbid=112
\n
\nExcellent sources of vitamin K include: spinach, Brussels sprouts, Swiss chard, green beans, asparagus, broccoli, kale and mustard greens. Very good sources include green peas and carrots.
\nFermentation of foods can be especially helpful for increasing their vitamin K content. Within this fermentation category, soy foods have a special place in the nutrition research on vitamin K since fermented soy foods play a unique role in supplying vitamin K in certain traditional cuisines (like that of Japan). You will sometimes find the word "natto" being used to refer to these fermented soy foods since Bacillus natto are bacteria that can convert K1 into K2 and are often used in the production of fermented soy products. Yet, fermented soy foods are not alone in the vitamin K-rich fermented foods category. Some cheeses are also fermented in a way that optimizes their vitamin K content. Proprioni bacteria, for example, make large amounts of one type of menaquinone called MK-9(H4) and cheeses fermented by these bacteria can be a rich source of vitamin K. Swiss Emmental cheese and Norwegian Jarlsberg cheeses are examples of cheeses fermented by proprioni bacteria.
\nIn the average U.S. diet, meats and eggs are the most common food sources of the menaquinone MK-4. Fermented soy foods are our most common source of MK-7. (Remember that all forms of vitamin K including menaquinones like MK-4 and MK-7 and also phylloquinones make great contributions to our health.)
\nMany forms of lettuce contain worthwhile amounts of vitamin K. It is worth noting here that on an ounce-per-ounce basis, romaine lettuce may be about four times higher in vitamin K than iceberg lettuce according to studies conducted at the U.S. Department of Agriculture.
\nSince vitamin K is a fat-soluble family of nutrients, foods tend to become higher in vitamin K as they become less concentrated with water. For example, on an ounce-for-ounce basis, tomato paste is higher in vitamin K than fresh tomatoes.
\nSometimes the outer leaves of a plant can be more concentrated in vitamin K than the inner leaves. We\'ve seen research documenting this difference for both cabbage and Brussels sprouts. For this reason, it may be worthwhile to very carefully and gently scrub these vegetables with a natural bristle brush while rinsing them under a flow of clean water as a way to clean the other leaves and keep them included in your meal rather than simply discarding these outside leaves due to presence of dirt or other particles.\r\n

\r\n \r\n If you swapped eating the traditional high inflammatory Western diet of high sugar, carbs. omega 6 oils for a high fish diet, the artery inflammation that causes the arteries to form plaque would be substantially reduced by the increase in omega 3 oils which means there would be less need for higher levels of K2. Fish does contain K2 as well, mostly in the organs.
\n
\nCountries on high fish diets also tend to not eat much dairy which means there is not much spare calcium absorped that needs redirecting to the bones
\n
\n
\nCountries that eat a lot of fish usually eat plenty of vegetables and some of the K1 will be converted to K2 besides the K2 in fish. Some countries such as Japan eat natto to get K2. The synthesis of vitamin D from sun exposure works in a feedback loop that prevents toxicity and darker skin lowers the absorption rate as well.\r\n

\r\n \r\n Vitamin K does not interfere with coumadin it justs works contrary to what you are looking coumadin to do and that is to thin the blood... but this is only for K1 not K2. It can help regulate clotting factors if too much coumadin has been taken.
\n
\nK2 is noted for keeping the blood fluid in a normal state as well as depositing calcium in bones instead of vessels.
\n
\nAntibiotics can decrease the vitamin K that should be produced by flora in the gut. Antibiotics are dangerous in so many ways.

\nI agree with everything you wrote. I\'m not saying vitamin k2 isn\'t needed or anything of that nature, but it appears that it\'s being indicated that if you take vitamin D you need k2, which doesn\'t make sense as far as diet.
\n
\nI mean if I had an eastern diet and say I over did vitamin D from food source and the sun, does that indicate I\'m gonig to have a heart attack?
\nIt seems that most vitamins you should take together normally come together from the same food source, but you can\'t get vitamin D and vitamin k2 from the same food source.
\n
\nSo why if I over dosed on vitamin D from food sources I would be alright.\r\n

\r\n \r\n Thanks liverock,
\nThat makes sense and I guess maybe people who take a lot of vitamin D should supplement with k2.
\nI take 1,000 in the morning of d and another 1,000 at night, so 2,000 in total, while I know a lot of people here take 4,000 or more a day.\r\n

\r\n \r\n This is the biggest problem with consuming your nutrition through synthetic isolated vitamins.
\n
\n3 oz. of salmon or mackerel provides you with about 100% of the RDI of vitamin D. Egg yokes are another good source. And of course the sun is free.
\n
\nIf you need to take a supplements, don\'t assume that more is necessarily better, as taking more can increase the chances of negative effects (such as imbalances). That\'s why it\'s best to supplement with the smallest amount necessary, while getting a bulk of your nutrition through food.\r\n

\r\n \r\n So I am revisiting this article today. This quote below addresses specifically the issue regarding Vitamin K2 and vitamin D
\n
\nVitamin K2 activates a protein hormone called osteocalcin, produced by osteoblasts, which is needed to bind calcium into the matrix of your bone. Osteocalcin also appears to help prevent calcium from depositing into your arteries. In other words, without the help of vitamin K2, the calcium that your vitamin D so effectively lets in might be working AGAINST you -' + '- by building up your coronary arteries rather than your bones.
\nThis is why if you take calcium and vitamin D but are deficient in vitamin K, you could be worse off than if you were not taking those supplements at all, as demonstrated by a recent meta-analysis linking calcium supplements to heart attacks.
\n
\nThis meta-analysis looked at studies involving people taking calcium in isolation, without complementary nutrients like magnesium, vitamin D and vitamin K, which help keep your body in balance. In the absence of those other important cofactors, calcium CAN have adverse effects, such as building up in coronary arteries and causing heart attacks, which is really what this analysis detected. So if you are going to take calcium, you need to be sure you have balanced it out with vitamin D and vitamin K.
\n
\nIt does not seem to support that taking D will cause an adverse effect if you don\'t take K. What it is saying to me is that taking calcium alone can cause an adverse effect. Although K2 may be important for better calcium placement other studies have confirmed multiple times that D3 alone will contribute to proper calcium placement.
\n
\nI am of the opinion that calcium should not be supplemented in people who are eating correctly in the first place and if supplementation should be required generally no more that 300mg a day should be taken along with equal amounts of magnesium. Almost everyone in the USA needs D3 supplementation.
\n
\nAn interesting study out of India supports the idea that D3 alone promotes calcium placement in the bone. In nursing homes patients are given 600,000 IU injections of D3 annually. Studys show that the patients who do this have far less femur fractures and stronger pelvic strength. No vitamin K2 is given... so that is a good case for D3 alone.
\n
\nIt is calcium that can cause havoc without D3, and as this study suggests K2 will have a positive effect also... I see no direct relationship between K2 or lack of it causing problems with D3 supplementation alone. In fact it addresses the supplementation of Calcium and D3, not D3 alone. So an excess of calcium may actually be the culpret in arterial calcification.\r\n

\r\n \r\n Both vitamin D3 and K2 are fat soluble vitamins and should be taken with food for best effect. It might be good to take them with your coconut oil
\n
\nmaybe the way the dosages keep increasing on vitamin D it wont be too long before were up at the 50,000 iu level... which is what I found to be actually visibly therapeutic... \r\n

\r\n \r\n Arrow, I have read somewhere about taking 50,000 of D3 but only for a short time, how long do you think is safe at that level? Can vitamin D3 build up in the body and be harmful? At the 50,000 dose for an extended period of time would you need to have blood tests?\r\n
